I'm Supergirl. I've always been Supergirl. I should've told you so long ago, I know that. I just kept making excuses because you've been hurt so many times. And, I convinced myself that I was protecting you and then one day you were so angry with me, with Supergirl, but you still loved Kara. And I just kept thinking, if I could be Kara, just Kara, then I could keep you as a friend. I was selfish and scared and I didn't want to lose you. So, I kept pretending and I never stopped. And every time I kept my secret from you I wasn't protecting you, I was hurting you just like everyone else and I am so so sorry. I am so sorry.
Kid: Thanks Supergirl! When I grow up, I want to be just like you. Kara: Well that's easy, you just have to fight for what’s right and always tell the truth. Lena: Always tell the truth, that’s rich. Kara: Miss Luthor, is everything alright? Lena: Why so formal? I thought we were best friends, Kara.
