Supergirl, Season 5

Lena:
You're dead.

Lex:
So, you remember everything?

Lena:
Of course I remember everything! I killed you!

Lex:
Yes, that's right, you killed me. But that is in the past. Because I'm back now, and I forgive you.

Lena:
What are you talking about? What is happening?

Lex:
Well, it was, uh... sort of a Crisis.

Lena:
It was an... antimatter wave.

Lex:
Ah, yes.

Lena:
Alex and I worked together.

Lex:
Mmm-hmm.

Lena:
We built a portal... The wave still came.

Lex:
Yes, and billions were lost and the multi-verse collapsed, and it was all every interesting. What matters now is that a very powerful person brought me back to life to help. But I refused to do so, unless he promised that you would make through okay, and you have, with your noggin intact.

Lena:
You gambled the fate of the entire multi-verse to get your own way?

Lex:
It gets better. In this new world, we work side by side as Luthor Corp and the DEO to make the world a better place.

Lena:
So I'm in hell.

Lex:
No, no, you're in a new reality. To the outside world, we're billionaire philanthropists. It's the perfect cover.

Lena:
I want nothing to do with you.
