Supergirl, Season 5

Kara:
I can't believe even William is drinking the Lex Kool-Aid.

Alex:
Well, you gotta give him a little break, okay? The only people that know the truth are the ones whose memories have been restored. So it's Brainy, Nia, Kelly...

Kara:
All the heroes who helped at the Crisis, including you know who, which just makes my blood boil.

Alex:
Well, the Luthors are a breed of their own.

Kara:
Yeah. Speaking of which, I have to talk to Lena.

Alex:
Look, on this Earth, Lena and Supergirl are partners. And as far as I'm concerned, she's not trying to mind-control the planet. Plus, she doesn't hate you, so... so maybe Lena not having her memories is a good thing.

Kara:
No, no. As much... as I would love to have a clean slate with Lena, I owe it to her to tell the truth. I made that mistake once; I'm not gonna do it again.
