Much like the Berlin story arc, everything came together in these episodes; all the Blacklisters appointed during this season functioned as an irreplacable cog in a machine that is the master plan to exonerate Elizabeth. The result is a wonderful two-parter which was not only exciting, but also very fun to watch.
Many of this can be credited to the outstanding interaction between Spader and Strathairn; their outstanding performances, up to the tiniest nuances (such as Peter's face when Hitchin mentioned his name in her statement) make this episode one of the best in the series. The Director was a great character and antagonist, and I will miss hating him (the character, not the actor, who is amazing).
As a Dutchman I cannot help but comment on the language and portrayal of the country at the end of the episode; that TV is probably older than I am, and some of the clothing is from over a century ago. The odd thing is that the TV, despite its very poor Google Translate headline, actually has fairly accurate spoken Dutch, whereas the actors themselves sound nothing like us. It's weird they know how to do it (especially considering there is at least one Dutch actress on their payroll), but decide to do it like this.
It did not really bother me as I primarily remember the scene for being hilarious, and it definitely did not hinder my enjoying of this episode (hence the 10 star rating regardless), but just wanted to mention it.
