Supergirl

[once The Flash is revealed to be in National City]

Cat Grant: There's a new superhero in National City. This is huge; direct competition for Supergirl.

Kara Danvers: He doesn't have to be... competition.

Cat Grant: Would you prefer... a sidekick?

Barry Allen: No, not a sidekick. More like an equal, or an ally...

[Winn pats Barry's shoulder]

Barry Allen: ... a new partner, maybe?

[Cat stares stoically; Barry nods]

Barry Allen: Speaking was the wrong choice. I see that now.
