Alex: Scan me. My mind.
Alex: Something is wrong with me, J'onn. I don't know how to describe it, I just feel disconnected. I feel vulnerable. What if something went wrong when I underwent the truth seeker? Look, I know there's not supposed to be side-effects or anything, but that's when this began. I just need to know that I'm okay. And if I'm not okay, I just need to know that I'm not crazy. Please, J'onn.
Brainy: I have discovered the species we apprehended last night.
Alex: They're human?
Brainy: Oh, no. Not just human. Frat boys.
Kara: But who am I without you? The whole reason I became Supergirl... it was to save you.
Alex: And I'm still going to be the reason. I'm still going to be me. And you're still going to be Kara, my sister. I just won't know that you're Supergirl.
I had to.Alex Danvers (punches Colonel Haley)
You had me fooled, Danvers. I thought you were a soldier. But then I find this out. All the lies you must have told. You have undermined everything that we stand for, all to protect your own sister. Supergirl.Colonel Haley

Just because I don't work at the DEO anymore doesn't mean I'm going to stop being a hero. No matter what you say.
The world doesn't need a Superman when it has Supergirl.Clark Kent

Kara: You're a monster.
Deegan as Dark Superman: No, I'm Superman.
Barry Allen: You can't just write yourself as a hero. It doesn't work that way.
Deegan as Dark Superman: Doesn't it, though? You were struck by lightning, I was given the book by a higher power. Both random acts of chance. This is my destiny so much more than becoming The Flash was ever yours.
Barry Allen: People don't become heroes because of circumstance. They become heroes in spite of circumstance.
Oliver Queen: You're just a cheap knockoff.
President Baker: The United States does not want a war with Supergirl.
Supergirl: Then I trust you won't start one.
