Possible Scene in Episode 1
Kara uses her powers to help people for the first time and is met with a disapointing response from her foster sister:
ALEX: Why can't you just text me whatever your big thing is? I've got a meeting with Henshaw in five...
KARA: Can't see your face over the phone.
ALEX: OK, you have three seconds.
KARA: I did it, Alex. I did what you always wanted me to do.
ALEX: Your hair looks exactly the same.
KARA: No, I saved them. I did it, I stopped them from going over the bridge, those people are alive because of something I did.
ALEX: You could've been killed.
KARA: How? I could bend this steel desk into a little ball if I wanted to, you've seen what I can do.
ALEX: Then they could've been killed, it's not like you've had a lot of practice stopping trains.
KARA: You always said that if you had my powers, you'd use them to change the world. I came here to say you were right, I'm going to.
ALEX: How?
KARA: By finally being the person I was sent here to be.
ALEX: You have not thought this through. You expose your powers. Outside, in daylight, to the general public. Do you have any idea what the odds are someone has taken a photo, maybe a video, of you stopping that train with your hands? I'm going with 100%. You're probably already trending.
KARA: They would've died without me. I don't get it, I thought you'd be proud.
ALEX: Our whole childhood, you hid your abilities like they were disabilities. You made me, our family, your co-conspirators. And now you walk in here, announcing a career change? What's next, law school?
KARA: Today felt like the first day of my life. I felt like I was back home.
ALEX: In Midvale?
KARA: Krypton. I mean...I had to do something spectacular just to feel normal.
ALEX: Whatever you're going through, it'll pass. Just don't do something you're gonna regret.
KARA: I just told you about the best moment of my life, and you can't even be happy for me.
ALEX: Kara... You may have his abilities, but you're not him.
KARA: No. You're right, I'm not. I am Kara Zor-El. Daughter of Alura. And I'm gonna start living like it.
