Winn: I've been searching for my calling. This is it. I must save the future. What about you?
James: I can't keep waiting on the world to change. My future's now.

People like you and me, we do what it takes to get what we want. And when we defeat Reign, I have no doubt you'll figure it out.

Lena

J'onn: I'm not ready.
M'yrnn: You are. You looked into the flames and you had no fear.
J'onn: That's because you were with me.
M'yrnn: That will never change, J'onn. Never.

Kara: You're all clear kid. Now let's blow this thing and go home.
Brainy: I assume that's some sort of film reference.
Kara: We never showed you Star Wars? Not a single Star War?

Sam: Then it's settled. I'm going back to the Dark Valley.
Alex: Sam, you're took weak.
Mon-El: We don't have Brainy to get you there.
Sam: Lena was able to do it.
Lena: That was using electric shock, and in your current condition, Alex is right. I don't know if you'd survive.
Sam: That's a risk I'm willing to take if it means ending Reign and saving the world. And I have to do it for my daughter. I promise you, I am not dying today.

Mon-El: I lost her once, Winn. I'm not sure I can do it again.
Winn: Wow, really? Dude. Dude, forget Reign, you need to get back here fast so we can get a drink.

M'yrnn: By the end of this, you will not feel loss, J'onn. You will feel complete. I promise.
J'onn: How do you know?
M'yrnn: Because I know the hole that comes with not doing this, the way I felt when your mother was taken from me, when you were taken from me. Be patient, my son. Let the memories fill you up, as they have filled me up.

Home is not a place, it is living among those who love and honor you. I can depart this world with peace, because I know my son is home.

M'yrnn

You think that gun gives you respect? It has no power. It's just a tool for spreading fear, and fear is not respect.

J'onn

James: I've never really understood that argument. That someone's right to own an assault weapon is more important than someone's right to go to school safely.
Lena: I have a gun for self-defense. I have used it for self-defense.
James: You're not telling me that you're one of these people that thinks that having a gun makes everyone safer, right?
Lena: We disagree, but I can see your side, and hopefully you can see my side, too.
James: I'm open to listening.

Kara: Do you think I'm being paranoid?
Mon-El: If I have learned anything, it's that your instincts are usually spot-on.

Kara: When you went away to college, we figured that out, we did that.
Alex: Yeah, I mean we called and emailed every day. What's Wi-Fi like in space?

Supergirl Season 3 Quotes

Reporter: Does President Marsden believe climate change is real?
Cat: Yes, Carl, as a matter of fact she does. She also believes that two plus two equals four, and that the Earth is round, because the President is not a moron.

Winn: I thought it was bad when she skipped pizza night, but skipping free apps? I mean, come on. These are like the beginning of the dark days.
J'onn: Hey, come on, grief doesn't have a deadline.
Winn: Look, I know, but I mean, she goes from being little miss sunshine to, well, Alex basically.
Alex: What? I'm not like that.
J'onn: Oh come on Alex, your unrelenting seriousness is one of your best qualities.
