Cat and Kara in “Unfinished Business”

Cat

Tell Mr. Allen to have a good time zipping around in his red outfit.

Kara

Wait, you knew he was the Flash?

Cat

Oh, please. Barry shows up, the Flash shows up, his insistence on that silly name, and he was so unfailingly charming and nice that he had to be either a superhero or a Mormon. Kira, I can spot the extraordinary pretending to be a nobody in my midst just like that! [snaps her fingers right in front of Kara's face.]
