Warren Fox

In May 2006, it was announced that Lomas would arrive in Hollyoaks as "bad boy" Warren Fox.^[1] In regards to Lomas and Whittle's casting, a Hollyoaks spokesperson stated: "We're delighted to welcome Ricky and Jamie to the Hollyoaks cast. Their characters are set to bring lots of drama to the show!"^[1]

In 2009, Lomas decided to quit the soap opera after three years. He said: "I've had a fantastic three years at Hollyoaks but having fully explored the character, I felt the time was right for me to move on. I'm delighted to be going out as part of such a dramatic storyline and my final scenes are some of the most dramatic I've ever filmed. I'm sure viewers will be hooked!"^[2]

Following the announcement of Warren's return in October 2010, Lomas was asked if he thought the character changed since his last appearance. He replied, "I don't think you can really change a character like Warren. I think it would be a little boring if he came back as some sort of softie but, like I say, there are new people around now for him to bounce off."^[3]

During an interview with Digital Spy, Lomas admitted he initially wanted to stay on the show for only two years: "Well I wanted to go after two years. I sat down with Bryan Kirkwood who told me what he had in store and it was too good to refuse! The storyline was so fantastic."^[4] He later revealed how he felt about his final appearance, admitting: "To be honest with you, when I knew I was filming my final scene – obviously I've spent three years of my life there and I've got lots of good friends there – I got really emotional. I had to take myself off and have a word with myself and say 'Come on – you need to pull it together!' It was great because all the producers came down and clapped me and bought me a bottle of champagne. It was very emotional."^[5]

Lomas was announced to return to Hollyoaks in October 2010 after the character was revealed to have survived the fire.^[6] Series producer Paul Marquess commented on Warren's return, saying: "We were hopeful that Jamie's return would be the best-kept secret in soap history, but when Jamie arrived on set it proved impossible. When Warren Fox died in the Loft fire, we all thought that was the end of the dangerous gangster that terrorized the residents of Hollyoaks village. But when our writers made the shocking suggestion to bring back Warren in a juicy plot, it was just too irresistible to ignore as they not only made it feasible that Warren could have escaped the fire and fled the village, they created an explosive and very clever plot with lots of twists and turns that is guaranteed to have the audience hooked. When the idea was pitched to Jamie, he knew it was too good an opportunity to miss. Warren Fox was one of the soap's most memorable villains and we're very excited about his return."^[6] He returned on 29 October 2010.^[7] Lomas later expressed his feelings about returning, saying: "I'm really excited. I got the call and I got told about the storyline and it was great – full of twists and turns. I kind of thought that my character had run his course with the other characters that were around before, but there's a new breed in now, so that means plenty of potential for Warren to come back in and cause some more mayhem."^[3] On-screen, flashback sequences were filmed to show how Warren survived the fire.^[8] Hollyoaks announced a special episode centered around Warren and how he survived the fire to be broadcast on 1 December 2010, shown to viewers in various flashbacks.^[9]

In August 2011, it was announced that Lomas had decided to leave the serial once again,^[10] and he filmed his final scenes in October 2011.^[10] His departure was broadcast on 23 December 2011.

In March 2016, it was confirmed that Lomas had agreed to reprise his role as Warren.^[11] The character returned in reasonable fashion where Warren was seen in a "sexy shower stunt".^[11] He returned on 26 May.^[11]

On 3 November 2017, Lomas announced that he had left Hollyoaks once again and Warren would depart on-screen the following week. Lomas made the announcement during a live televised interview on This Morning.^[12] His departure storyline saw him leave with his new-born daughter, Sophie. Lomas decided to leave because he wanted to participate in the seventeenth series of the reality television series, I'm a Celebrity...Get Me Out of Here!^[13] Warren departed during the episode broadcast on 7 November 2017.^[14]

On 30 March 2018, it was reported that Lomas was in talks with producers about a potential return.^[15] Lomas agreed to return for one episode which aired on 21 May 2018. Warren's return storyline featured him taking his son Sebastian from Sienna and absconding.^[16] On 23 July 2019, it was announced that Lomas had agreed to re-join the show's regular cast. Lomas initially filmed scenes for a story to air in late 2019, with his full-time return scheduled for 2020.^[17] Warren's reintroduction occurs following Sienna tracking down the location of her children that Warren abducted.^[17] Lomas' indefinite return began from the episode broadcast on 9 January 2020.^[18]

On 12 March 2024, it was announced that Lomas had quit the show for the fourth time and Warren departed on 11 September 2024.^[19]

Warren arrives in Hollyoaks in June 2006 to demand money from Sean Kennedy (Matthew Jay Lewis) as compensation for having him jailed, but is willing to write off Sean's debts in exchange for a night with his wife, Louise Kennedy (Roxanne McKee), who refuses. Warren enters into an affair with Clare Cunningham (Gemma Bissix), whilst she is still married to Max Cunningham (Matt Littler). They are taped by Mel Burton (Cassie Powney), who later shows the footage to Sam "OB" O'Brien (Darren Jeffries) and Sophie Burton (Connie Powney). Mel and Sophie are killed afterwards, and OB is severely injured, in the explosion at The Dog in the Pond. OB tells Max about the affair and he fires Warren from The Loft, who later hires thugs to trash the building. Max reluctantly signs his half of The Loft over to Warren. When Clare returns, she and Warren become partners in owning the business, though they get into a dispute afterwards.

Mercedes McQueen (Jennifer Metcalfe) sleeps with Warren after being accused of infidelity by her boyfriend, Russ Owen (Stuart Manning). When Warren learns of Sean's return and demand of £10,000 from Louise, he agrees to help Louise amass the money. Warren later kidnaps Sean and kills him. He supports Louise after she ends her relationship with Calvin Valentine (Ricky Whittle). After sleeping together, Louise guiltily reunites with Calvin. Justin Burton (Chris Fountain) later lives with Warren, who is arrested for Sean's murder after Clare alerts the police. He is released after Sean's body could not be found. Warren is arrested for the attempt on Clare's life, but is pronounced innocent when Mercedes admits she was with him. Warren visits Justin in the hospital, revealing he was the assailant who almost killed him with a car and later.

Warren grows fonder of Justin, who begins working for him, as Louise and Warren's relationship becomes more serious. Clare continues to try and drive Louise and Warren apart. Warrens threatens to push her from the balcony if she does not sign over The Loft to him and leave Hollyoaks, to which she agrees. Days later, Warren returns home to his flat to find it trashed and no sign of Katy. Warren, Justin, and Max begin looking for her, and are later called by Clare, who tells them she has Katy. Clare tells Warren that she wants revenge on Justin for pushing her over the balcony. Warren pretends to kill Justin. Clare is not fooled and drives off with Katy tied up in the car. She crashes over a cliff and falls into the water below. Warren, Justin and Max jump in and rescue Katy. Katy attempts to try to tell Louise that Warren killed Sean, but he ends up proposing to her, and she accepts. During their engagement party, Louise becomes suspicious of Warren's dealings, and is later attacked in Evissa by Ste Hay (Kieron Richardson), who leaves Louise for dead. Calvin saves Louise, and Warren beats up Ste the next day.

After a poker game with Tony Hutchinson (Nick Pickard), Mike Barnes (Tony Hirst) and Darren Osborne (Ashley Taylor Dawson), Warren ends up winning Darren's half of The Dog. Warren's old friends appear at The Dog and hold everyone hostage, which ends with Darren getting shot. Louise feels she cannot trust Warren anymore, but forgives him when he signs back his half of The Dog to the Osbornes. Newt (Nico Mirallegro) and Lauren Valentine (Dominique Jackson) find Sean's body, and Warren confesses to Louise that he killed him. Louise is furious, but becomes angrier when she finds out Katy knew. Louise then exposes Katy and Zak Ramsey's (Kent Riley) affair to Warren. Katy is angry when Louise agrees to become an alibi for Warren on the night of Sean's death as she does not want him to go to prison. Katy tells Warren to admit to the murder but he refuses. She decides to leave, but is dragged from a taxi by Louise and Warren. After Warren attempts to convince Katy to stay, she leaves. Louise is later arrested for Sean's murder. Warren and Darren persuade mentally unstable Jake Dean (Kevin Sacre) to confess to Sean's murder, and Louise is released.

Mandy Richardson (Sarah Jayne Dunn) helps Warren plan his wedding to Louise, who becomes very suspicious of Warren and Mandy, believing they are sleeping together. Cindy Cunningham (Stephanie Waring) pushes Louise further into believing this. Louise turns to alcohol, which drives Warren to confide in Mandy and begin an affair. Ravi Roy (Stephen Uppal) finds Mandy and Warren sleeping together on one occasion, but agrees to keep quiet. Nige Foster (Sam Townend) is revealed to be alive, and Warren pays Nige money to stay hidden so that it keeps Calvin on his side. Calvin agrees to take part in a raid on The Loft after he is approached by DI Mark Gascoyne (Craig Russell). Not having time to warn Warren about the raid, Calvin goes along with Mark and two other officers, whom he later discovers are not police officers and that the raid is unofficial. Mark gets Calvin to beat Warren up as revenge. Calvin agrees, but he phones an ambulance afterwards.

Mandy tells Louise about the affair and the pair plan revenge on Warren after Louise tells Mandy that Warren killed Sean. They come up with a plan to steal Warren's money and go to the police about the murder. Louise sees CCTV footage of Warren and Mandy sleeping together in The Loft and decides to murder Warren and frame Mandy. On the wedding day, Warren, Ravi and Spencer arrive at the hotel where the wedding is being held. Warren goes up to Louise's room where he hides a necklace for her, but finds the gun which she plans to use to kill him. Warren takes the gun and removes the bullets as Louise returns to the room. He gives her the necklace and asks if the gun was his present. Louise reveals she hates Warren because he had ruined her life, killed her husband, and cheated on her. Warren begins crying and apologizes to Louise, telling her that he wants to start a family with her. Louise picks up the gun and tells him she could never bring his child into the world. However, Louise discovers the gun is empty and Warren reveals he has the bullets. Warren attacks Louise and kills her. The wedding party believe Louise left Warren due to his affair, unaware of her death, and Warren watches as Mandy leaves the village with Tony. Calvin and his wife, Carmel (Gemma Merna) approach him in an attempt to comfort him, and she mentions that Louise was pregnant, leaving Warren devastated.

Warren captures the affections of Sasha Valentine (Nathalie Emmanuel), who Warren asks to help look after Spencer Gray (Darren John Langford). He upsets her by having a one-night stand with Sarah Barnes (Loui Batley), but Warren and Sasha eventually begin a relationship with her moving in. Calvin makes numerous attempts to stop his sister from seeing Warren, however it only pushes her away. Calvin then records a confession from Warren that he murdered Sean and Louise. Mark arrests Warren, but later tells Calvin that the recorder has not worked and that Warren will be released. Calvin goes to see Warren at The Loft and a fight breaks out. Warren is knocked over The Loft balcony. Sasha breaks them up as onlookers watch. After Calvin announces Warren as a murderer in front of the villagers, Sasha takes Warren's side.

Warren becomes the victim of a hate campaign with posters spread around the village declaring him to be a murderer, and he receives anonymous phone calls and poison pen letters. In an attempt to leave the village with some money, Warren makes a deal with Justin to burn down The Loft for £5,000 so that he can claim the insurance money and Justin can get money to start a new life with Hannah Ashworth (Emma Rigby). Justin agrees and goes to meet Warren at The Loft, but is stopped by Calvin who tells him not to get involved with another of Warren's schemes. Justin changes his mind and leaves, only to be seen by Sasha. While waiting for Justin in the club, Warren is knocked out by Clare using a baseball bat. She tells him that both he and Justin have ruined her life and makes Warren call Justin to meet at The Loft. Calvin then arrives to speak to Warren and finds Warren tied up, Clare with a match and The Loft covered in petrol. He is about to call the police, but after Warren taunts Clare by saying that he always wins, Calvin backs off and leaves his fate in Clare's hands. Hannah arrives at The Loft to find Justin and Clare accidentally knocks her out. She wakes up and attacks Clare, who drops a match onto the bar, and the pair fall through the banister to the floor below unconscious. Justin enters The Loft through the upstairs door, where he finds Warren tied up. Justin asks him where Hannah is and Warren tells him that she is not there. Justin starts to untie him but he hears Hannah's calls for help and realizes that Warren lied. He leaves him in the fire and escapes with Hannah. Clare is nowhere to be seen and has escaped. Warren unties himself and realizes he cannot get out of the balcony door so jumps down the cellar door, he lands on his ankle on the stairs and breaks it. Warren looks up at the ceiling mirror, which collapses onto him.

Over a year after his supposed death, Warren returns to Hollyoaks in October 2010. He breaks into Chez Chez and leaves a dead fox for club owner Cheryl Brady (Bronagh Waugh). The next day, Warren follows Mandy in the village and is seen by Tom Cunningham (Ellis Hollins), who claims to have seen Warren's ghost. Warren is later seen by Tony walking past the village walls. Mandy and Warren meet, revealing they are in a relationship and have had contact since their last encounter. Warren tells Mandy that they are going to destroy Tony as revenge for him leaving her abroad. The following day, Warren and Mandy argue and she threatens him. He later enters the McQueens' home and asks Theresa McQueen (Jorgie Porter) who she has told and mentions that someone else knows. It is later revealed that Theresa witnessed Warren escaping The Loft and that he has been blackmailed since then. On another occasion, Warren threatens to push Theresa from a roof in the village if she does not tell him who has been blackmailing him. Warren reveals how he escaped the fire: days before the fire Warren meets a suicidal man named Dale Greer (Chris Geere). Dale and Warren bond and he begins working for him. When Clare starts the fire and Warren is apparently killed by the mirror, the floors collapsed and Warren is found by Dale in the cellar. After being rescued by Dale, Warren realizes everyone believes he is still in the club, and he kills Dale before putting his body in the cellar. Warren then threatens to kill Theresa, who witnesses him escaping if she tells anyone and then leaves the village. With Warren still threatening to push her, she admits she killed Calvin and they start a platonic relationship, in which they both protect the other's secret.

Warren breaks into Chez Chez and tries to break the floor with a sledgehammer, but he is interrupted by Brendan Brady (Emmett J. Scanlan). Brendan asks who Warren is, and he lies, saying that he is Cheryl's boyfriend before phoning Mandy for information about him. Warren enters The Dog to the surprise of local residents. Claiming to have suffered from amnesia, Warren pretends to regain some of his memory of several people. Warren later confronts Tony and the pair have a stand off, with Tony threatening to attack Warren for telling Dom to burn down his restaurant which resulted in Steph and Malachy's deaths. Warren leaves and Brendan tells Tony to call the police and inform them that Warren is still alive. He is later arrested and taken into custody to be interviewed by DC Ethan Scott (Craig Vye). Warren tells Ethan to speak to his commanding officers and later Warren is released. After returning to the village Warren meets with Cheryl in time for Christmas. A few days later Warren returns to the club where he starts to dig up the floor. Danny Houston watches Warren on the club's CCTV and calls Brendan, telling him to find out what Warren is up to, believing him to be in league with the police. Brendan locks Warren in the cellar and demands to be told everything. Brendan then leaves Warren locked in the cellar until he admits to what he is up to. Warren and Brendan plan to get Danny's half of the club from him, but Brendan kills Danny. Warren helps Brendan get rid of Danny's body in the pond by the Dog.

Warren learns that Mandy had been sending him the texts in order for him to come back to Hollyoaks with her, and he scares her out the village. In order to stop Theresa from being sent to prison, Warren arranges for Kyle to be beaten up meaning the court case has to be postponed. Brendan helps Warren by getting Kyle to escape from the hospital, leaving him to go on the run. Brendan jumps to the wrong conclusions believing that Warren really killed Calvin and that Theresa is taking the blame for him. Brendan pretends to be Warren and encourages Kyle to seek revenge on Theresa.

Although Warren is supposed to be with Cheryl, he cheats on her with Mitzeee (Rachel Shenton). Warren does not understand why she is interested in Brendan, not knowing their relationship is fake. Warren and Mitzeee almost sleep together but are stopped before they have chance when Cheryl walks in. Warren reassures Theresa when she hears that Kyle is still around, thinking that Brendan has ensured that Kyle took the money and ran. Warren becomes suspicious when Kyle comes to Chez Chez asking for Warren, and he later sees him talking to Brendan. Warren desperately persuades Theresa not to leave with her baby in fear of Kyle, but she leaves anyway. When Warren phones Theresa and Kyle answers, telling him that he is doing what they had arranged, Warren realizes that Brendan has been pretending to be him. At first Brendan refuses to tell Warren where Kyle has taken Theresa, but tells him when he realizes that Theresa and her baby, Kathleen-Angel, might die. Warren turns up and Kyle knocks him out. Warren regains consciousness afterwards and shoots Kyle in the back, not knowing that he is holding Kathleen-Angel, and Kyle falls down the lift shaft with her. Theresa is horrified and believes that Warren had been plotting with Kyle all along after what Kyle had said on the phone. Ethan, who had been pushed down the lift shaft by Kyle previously, helps Warren get Kathleen-Angel out but cannot get out himself. Warren urges Theresa to leave with Carmel and the baby but she goes back to save Ethan. She falls into the lift shaft while trying and forces Warren to save Ethan before she lets him save herself. He saves Ethan and then suddenly the lift plummets with Theresa still on top of it.

As Theresa fights for her life in the hospital, Carmel accuses Warren of being in love with Theresa. Warren makes sure Ethan stays quiet and Theresa thanks him. He then sleeps with Mitzeee before fighting with Brendan. They call a truce until Ste attacks Brendan with a baseball bat, which hospitalises him. Warren steals drugs from Brendan later that month and starts a relationship with Mitzeee. When Mitzeee's mother, Trish (Paula Wolfenden), is imprisoned, Ethan agrees to let her go if she gets a confession from Warren admitting to Louise's murder. She tries to tape record him, but Warren finds out. Warren confesses to Mitzeee about Louise's murder. On Hollyoaks Later, Warren is told by Mitzeee to get the truth from him about Mercedes. Warren then hires a prostitute called Honey for Seth Costello (Miles Higson). He later finds Seth over Honey's corpse and buries her dead body in the forest. Warren later tells Mitzeee that he tricked Seth into believing he had killed Honey. Seth's older brother, Riley (Rob Norbury), learns about the trickery and locks Warren down a mine. After escaping, Warren then reveals to Mitzeee he about Mercedes having an affair with Riley's father, Carl Costello (Paul Opacic). When he returns, he visits Brendan in prison.

Mitzeee spends one night at Riley's. Nothing happens, but Riley's brother Jason Costello (Victoria Atkin) takes a picture of them together and sends it to Warren. Carl and Mitzeee stop Warren from attacking Riley, but after the Costellos harass Mitzeee, she and Warren decide to destroy the Costellos on the wedding day. Warren fires Gilly and rehires Rhys within the day. Warren threatens Doug to keep quiet, and blackmails £50,000 from Mercedes and Carl. Carl gives him half, with the other half on condition of the truth not coming out at the wedding. Doug tells Warren he is going to tell the truth, and Warren throws Doug to the ground, forceing him to put copies of Mitzeee's book underneath each chair. Warren attacks Doug after seeing him tell Seth to expose the truth. In the end, Mercedes tells Riley about the affair at the wedding, and Warren attacks Doug after the wedding. Warren visits Brendan in prison to get his share of Chez Chez, but Warren organises an assault on him after being refused. When Ethan accidentally runs over Rob Edwards (David Atkins), Warren helps Ethan repair his vehicle and exploits the situation for Ethan's help. Mitzeee leaves Warren, and he throws Mitzeee's clothes into the river in retaliation before threatening Ste and Cheryl. When he threatens new DJ Joel Dexter (Andrew Still), Joel claims Warren is his father. Warren goes into denial, believing the claim to be either one of Brendan's games or a lie told to Joel by his mother, but Theresa convinces him to take a DNA test which confirms the claim. After this happens Brendan returns and he and Warren declare a truce but Warren tells Ethan he is going to kill Brendan and he wants an alibi from him.

Mitzeee and Brendan hatch a plan to get Warren out of the way by uncovering Louise's murder and getting him sent to prison. Warren tells Mitzeee he wants to marry her, but agrees to show her Louise's grave beforehand. Warren forces her to dig Louise's grave and orders Joel to shoot Brendan whilst they are in the car to find Warren and Mitzeee. Warren starts to strangle Mitzeee when she refuses to keep digging. Brendan arrives just in time to save her, and holds Warren at gunpoint, telling him that he shot Joel. Warren disarms Brendan before picking up a brick to kill him. Joel arrives and hits Warren with the shove and reveals he and Brendan came to an agreement. The police that Brendan called arrive and arrest Warren for Louise's murder. Warren tells Mitzeee he wished he had killed her and tells Joel he is no son of his. Brendan taunts Warren before he is taken away in a police car.

James Nightingale (Gregory Finnegan) gets Warren released early on legal technicalities. He poses as Mike Jones to trick Mitzeee's sister, Maxine Minniver (Nikki Sanderson), and starts a relationship with her. He tries to steal a key from her flat storing hidden money in order to pay legal fees, but Sienna Blake (Anna Passey) steals the key and blackmails him into helping her secure a murder confession from Maxine in exchange for it. Warren reveals that his real reason for being back in the village is to get vengeance for the death of his sister, Katy. Warren prepares to leave again, but Sienna gives him the key and they sleep together. Warren is then able to get Maxine to confess that she buried Sienna's father, Patrick Blake's (Jeremy Sheffield) corpse. Warren initially hides the fact from Sienna after discovering how vulnerable Maxine is, but Sienna pushes him and he reveals the truth. They call the police who investigate the part of the city wall where Patrick is buried. When Maxine returns from the police station, Warren and Sienna announce that they were together to make Maxine confess, and Maxine leaves.

Warren continues his feud with other residents. He rescues Sienna's daughter Nico Blake (Persephone Swales-Dawson) and her friend Peri Lomax (Ruby O'Donnell) whilst they are lost in the woods. The same day, Warren and Sienna begin a relationship after she separates from her husband Ben Bradley. Warren visits several places in the village relevant to his past, and discovers there is a hate campaign against him started by the Osbornes who have prohibited detailing his murderous past. Warren tries to bond with Peri's father Cameron Campbell (Cameron Moore), but he tells Warren he knows of his criminal past, leaving Warren angry. He breaks into the Osbournes' house and sends Jack an anonymous photograph of a police award on Jack's mantelpiece, and threatens Jack to end the hate campaign, or Warren will expose Jack's dark secrets regarding Warren's former cellmate Billy to the rest village.

Warren becomes friends with Freddie Roscoe (Charlie Clapham) after learning that he needs an engine for his van, and steals Dirk Savage's (David Kennedy) engine unknown to Freddie. Although Freddie threatens to pull the plug on the sale for lack of interest, Warren sells the renovated camper van to Mac Nightingale (David Easter) for £18,000. Aware of the financial difficulty the garage is in, Warren buys the Roscoe's garage from the bank. Darren turns to Clare's sister, Grace Black (Tamara Wall), for help to get rid of Warren. After learning that Sienna is still seeing Warren, Grace recruits Darren, Maxine and Tony to go burn down the garage, but she tips Warren off about the impending arson attack in a bid to win his trust. Grace invites Warren to the club for a business proposition and slides a gun over the table to Warren for protection, but he refuses. She takes his keys and phone and texts Sienna to go to the garage, and takes the gun with her to shoot her half-brother Liam Donovan (Maxim Baldry). Grace and Liam's brother Adam Donovan (Jimmy Essex) thinks Warren did it and attacks him in the restaurant. He retaliates then realises that he is being set up. Liam later gives the police his statement telling them it was Warren who shot him and Warren is arrested.

Warren is released as there is no evidence to prove that he shot Liam. He visits Grace in The Loft and tells her he knows she shot Liam and set him up, Warren physically threatens her and she complies. Warren takes full control of the Roscoe garage, renaming it "Warren Wheels". Warren tries to form a truce with Darren and Maxine, but Maxine is reluctant. When Darren and Nancy go into the woods to search for Patrick's body, they enter a bunker where Warren locks them inside. Nancy begs Warren to let Darren out due to an angina attack, but he refuses until he confesses to being part of Patrick's death. Sienna disregards Warren's threat and calls the ambulance, though they decide to take Darren and Nancy to the hospital. Warren refuses to let them out of the car unless they confess to Patrick's murder, but Nancy manages to get Darren out. Warren finds out that Maxine is pregnant and believes he is the father. He visits Maxine to find out the truth and is interrupted by Adam. The two of them fight until Maxine intervenes. Maxine lies to Warren and tells him the baby is Adam's, Warren doesn't believe her and warns her not to lie to him.

Warren enters the garage where DI Ryan Knight (Duncan James) waits. Ryan offers information of the whereabouts of Warren's son Joel (Rory Douglas-Speed), in return for information on Sienna and Maxine's involvement regarding the Patrick's murder. Warren loses his temper and demands to know where Joel is; Ryan refuses to tell him but leaves his contact card. Later that day he sees Sienna being harassed by DS Gavin Armstrong (Andrew Hayden-Smith) in the street, and confronts him. When Warren realises the police suspect Sienna of Patrick's murder, he organises false two passports for them both to leave the country, and tells her to flee later that evening. Warren later encounters Joel, and Warren asks him if he is working with Ryan, which Joel denies.

Joel leaves and Warren goes to meet his contact to collect the passports, Sienna calls him in a panic, advising him they need to leave immediately, but Warren has a change of heart and tells Sienna he needs to be a father and stay in Hollyoaks.

Warren learns from the hospital that the baby is his. He is determined to be a father again, but Maxine is accidentally locked in the hospital lift by Nico and Peri. Maxine later loses the baby and Warren overhears Nico on the phone to Peri so he angrily confronts her, and she tells him it was Cameron who did it so Warren locks him and Cameron in the lift, telling Cameron he hurt Leela.

As she goes into labour, Kim Butterfield (Daisy Wood-Davis) and Farrah Maalik (Krupa Pattani) locate Sienna and arrive to save her, but Warren catches them. They argue but soon come to an agreement to take Sienna to the hospital after Warren learns that she still has cancer where she gave birth to two healthy babies. After the babies are born, Sienna tells Warren to leave and never come back or she will tell the police everything he has done, including her kidnapping and Bart's murder. He packs his bags and says goodbye to his son Joel. Moments later Myra McQueen (Nicole Barber-Lane) walks into Esther's Magic Bean and shows Warren the video of Joel giving his sister the drugs that killed her. Warren knocks Joel out and ties him up in the garage. As he is about to kill him, Tony Hutchinson runs in and talks some sense into him. He relents and Joel is let go.

Warren returns to the village in 2020, after Sebestian falls ill. He kidnaps Brody to blackmail Sienna into donating her bone marrow to save him. Although Warren agrees to move back to the village so he and Sienna can co-parent the twins, he plans to leave as soon as Sebestian is cured. However it turns out that because Sienna had chemotherapy due to her cervical cancer, she can no longer donate bone marrow. Warren goes on a search party with Brody and Joel to track down Sienna but when he ends up at his childhood home town he is reminded and opens up to his past that he was bullied by someone called Felix Westwood (Richard Blackwood). Warren calls a truce with Brody and returns to Hollyoaks where he stays at The Dog and starts a casual relationship with Mercedes, leading Warren to then have a feud with Liam Donovan (Jude Monk McGowan), resulting in Warren being hospitalised. Warren awakens and tracks Liam down.

Sienna returns and Warren gives her a taped confession of the murders he has committed. After seeing Felix for the first time in years, Warren is told that the man Warren looked up to as a child, Cormac Ranger (James Gaddass) had abused Felix in the children home because of his race. Warren vows to help Felix get closure, and with Brody, they arrange a meeting with Cormac. This confrontation turns violent and Warren grievously injures Cromac.

Warren grabs a car and runs over Brody after he and Sienna escape Summer's plan, and covers his involvement in Brody's murder. Warren's murderous secret is exposed by Fergus after he intercepts an incriminating voicemail, but agrees to keep his secret.

Fergus is angry with Warren, who refuses to help him with his illegal jobs. Warren reminds Fergus that he is top dog and no one orders him around, which prompts Fergus to prove he is just as dangerous as Warren by killing Timmy Simmons (Sam Tutty) with Warren's gun. Warren is forced to help him dispose of the body and they bury him in the woods. Felix learns about Warren and Fergus' crimes, and tries to make Warren see that Fergus is using him.

Ruth Deller of entertainment website Lowculture has often criticized Warren; in one feature she slammed his final storylines stating: "Apparently he's still around and there's some tedious and unlikely 'romance' between him and Sasha. Oh, and he's bedded Swimbint (Sarah Barnes) for good measure. Really, didn't this character's point expire about two years ago now?"^[28]

Gareth McLean of Radio Times has been critical of Warren stating: "There are many bad apples in Hollyoaks, but only one that's rotten to the core. Warren Fox has caused so much misery to so many people – Russ, Mercedes, Ste, Cindy, the Barneses, the Deans and don't forget Justin – it's a wonder the villagers haven't ganged up, Murder on the Orient Express-style, and offed him."^[29]
