Supergirl Quotes

Kara: I recognize I made a mistake in hiding my identity from you for so long, but the past is the past and I can't change it. Forgive me or not, that's your choice. Just like it's your choice to work with Lex. I'm done blaming myself for your bad decisions.
Lena: Then why are you here?
Kara: To tell you that from now on, you're accountable for your own actions. If you decide to forgive me, I will be there for you. But if you continue to work with Lex, if you go through with whatever it is the two of you are planning, I will do everything in my power to stop you. Just like I would any other villain.

Lena: It's you. Kara Danvers is Supergirl.
Kara: Yeah.
Lena: Can't believe I was fooled by a pair of glasses.
Kara: Don't worry, a lot of people are.
Lena: Oh god, I'll have to recall all those alien detection devices because they clearly don't work.
Kara: You're not angry?
Lena: No, it's incredible! I mean, you're incredible! But why are you trusting me with such a big secret? You barely know me.
Kara: Because I know that what you want more than anything is to do good. And I know it's hard for you to trust people, but I need you to know now, without a doubt, I trust you. My cousin, your brother, they got it wrong. Imagine what we could do together, a Luthor and a super working together as a team!
Lena: If we were partners, we could change the world.
