Supergirl, Season 4

Nia:
Maeve was always my biggest supporter. I can't believe she'd say something like that.

Kara:
Nia, I'm so sorry.

Nia:
I knew she was gonna be crushed about the powers, but... Kara, she was so angry.

Kara:
I know it's not the same thing, but if it makes you feel any better, I've been through a lot with my sister.

Nia:
I appreciate your support, but this isn't something that you can understand. I have alien powers, my sister doesn't. And now she hates me. [Kara pulls over] Why are you pulling over? [they climb out of the car] Kara, what are you doing?

Kara:
I do understand. Probably better than anyone. [removing her glasses, she takes off into the sky, then lands again] I am Supergirl. Very few people know my true identity because it's not safe for them to. But I'm telling you because I think it can help you. And I don't think it will harm you. You, too, are a hero. I was the sister with powers. And I watched Alex pay the price for it in so many ways. Most of the time, she handled it with grace, but I'll tell you, there were times that it got ugly. When we were younger... and even now. But I have faith that the love between two sisters will prevail in the end. I have to believe that. I just need you to know now that you are not alone. You have a family. You have me.
