Supergirl, Season 5

Lena:
Of course, you assumed the worst. I'm not the bad guy.

Kara:
I know. You spent years trying to be open and trusting, even when everyone expected you to be like your family. Even when everyone in your life let you down. [crying] Even when I was weak and lied to you, knowing that all you ever asked for was the truth, you were always better. Lex took advantage of my weakness and he used it to manipulate you. He wanted my mistakes to change you. He wanted you to become him. But you are nothing like him. Nothing. Don't let my mistakes turn you into something you're not.

Lena:
I am good. And I always was. Lex didn't change me, and you didn't change me, either. You just exposed me to the ugliness of humanity. You did me a favor, Kara. I learned what kind of deceitful person you are, and that's what inspired me to do this.

Kara:
Lena...

Lena:
Your words mean nothing to me anymore. Spare us both the drama. Leave me alone.
