Supergirl, Season 4

Lillian:
Why don't we have a cup of tea while Lex tells us why he summoned us here?

Lena:
He summoned us here to gloat.

Lex:
You think so little of me, Lena. It hurts. I'm a sentimental guy. I didn't do all of this for me, I did it for us. I mean, look, we all know if I wanted you two dead, you wouldn't be treading on the presidential seal having a tea party. Everything I've done has been strategic to lead up to this very moment. The Luthor name cleared. Our family poised to take its rightful place in history.

Lillian:
And what exactly are we poised to do?

Lex:
Revolutionize energy worldwide. I'm rounding up aliens and harnessing their power to be used and sold; sort of like supercharged disposable batteries.

Lena:
That's vile!

Lex:
Vile and viable. As another world leader once said, "I don't see why men shouldn't be as cruel as nature."

Lillian:
Try not to quote Hitler in public, dear. It'll hurt the brand.
