Winn: Uh guys, I just picked up on some sort of live transmission from Air Force One.
Kara: Air Force One?
Alex: Wait, don't tell me the President is heading towards the conflict and not away.
Kara: Every time I think I can't get happier I voted for that woman...

Kara: James, I'm so glad you're okay.
James: Yeah, me too. It's a war zone out there. Daxamite troops are beaming down from everywhere, setting up checkpoints, arresting resisters. It's almost like they're instituting their own Martial Law.
Winn: Not to mention the full on Independence Day going out there with the mothership hovering over the city.

Whatever happens next, I want you to remember never to doubt yourself again. You are a marvel, Lena. Any mother should be proud to call you daughter.

Rhea

Rhea: Still isn't working?
Lena: Was it me throwing it down in disgust or the sparks that gave it away?

Maybe she should give him like some action figures, right? Like if someone had given me action figures when they interrogated me about my dad when I was 10, I would have sung like a canary. I'm just saying.

Winn

James: Guardian is not...He's not this beacon of hope that I thought he would be. I mean, basically all I'm doing is beating people up.
Winn: Whoa, dude, we are doing a lot of good here. We're making a difference.
James: I mean, Supergirl, Superman, they're making a difference. They're changing hearts and minds. They inspire people. Guardian inspires fear.

Alex: What are you going to do to him?
J'onn: My job. Protect the identity of Supergirl and the DEO.
Alex: You gonna mind wipe him?
J'onn: Do you object?
Alex: No, just before you do that [punches Rick in the face]. Just make sure he remembers that.
J'onn: Will do.

Maggie: I told you not to rush in. Now you've made things worse.
Kara: I did what I thought was right.
Maggie: I should have been heard. I should have been listened to. I'm her girlfriend.
Kara: I'm her sister!
Maggie: And you think that trumps me? That you know what's right for her? I got her to be herself, Kara. I have just as much to lose as you do. You should have listened to me.

No. Kara. No. You do not give that terrorist what he wants. You cannot let yourself be blackmailed. You cannot open yourself up to that, ever. Do you understand me? Supergirl is bigger than me.

Alex

Maggie: I want to get her as badly as you do, but we can't punch our way out of this. We gotta get it right.
Kara: If the shoe were on the other foot Alex would already be out the door. I'm not waiting.
Maggie: You're not the only one who cares about her.
Kara: I'm going!

Rhea: I wish I had a daughter like you. Your mother must be proud.
Lena: Well that's not how I'd describe her.
Rhea: Mothers and daughters, not always the easiest relationship.
Lena: More like apocalyptic, but you know...

Mon-El: Alex, don't be embarrassed, ok? The first time I tried to microwave macaroni and cheese, they had to evacuate three city blocks.
Kara: That's an exaggeration, but I have seen less terrifying nuclear explosions.

Supergirl Season 2 Quotes

Kara: It's only been twelve hours since you asked me to choose a new position, and most of those hours I was asleep.
Cat: Really? I offer you the keys to the kingdom and you just go to sleep?
Kara: It was night time.

Kara: Wait, wait, wait, wait...this has always been here, with the glass and the views, and you made me fly to that cave everyday?
J'onn: The DEO has several facilities, Kara.
Kara: A bat bit me in the last one.
