Supergirl Season 4 Episode 15 Quotes

Lex and Lena Luthor, teaming up to save Superman's best pal. What would mother think?

Lex Luthor

I'm not the one who accidentally poisoned myself with Kryptonite in a quixotic attempt to kill an invincible man. And while I do find the irony that you now need the Black Kryptonite to cure yourself just delicious, you are my brother, Kex. I do want to save you. Besides, how can you pay your debt to society if you're already dead?
