Supergirl, Season 3

[Young Kara sneaks into her bedroom after her time with Kenny, only to find Alex awake in the other bed.]

Young Alex:
Where were you?

Young Kara:
None of your business.

Young Alex:
It is if I'm the one who would get in trouble for whatever dumb thing you were doing.

Young Kara:
I am so sick and tired of you blaming me for every bad thing that's happened to you.

Young Alex:
Really? Because my mom wasn't constantly on my ass before you came along. I didn't have to act like some Earthly ambassador to the teenage underworld before you came along, and I'm pretty sure my dad wasn't gone before you came along.

Young Kara:
How is that my fault?

Young Alex:
Before you crashed in that pod, I had a great life. With two great parents. Now all I have is you. And you are not worth it.
