Alex and Brainy in “Unfinished Business”

Alex

So you used your brain compartmentalizing thing with Kara?

Brainy

What does Kara have to do with anything?

Alex

Is this permanent or are you going to remember that she's Supergirl soon?

Brainy

Kara? Your sister with the glasses? [starts chuckling] Good one, director. They don't even look anything - Oh! Yes, my compartmentalization was on a timer.
