Damn, this show really hates sisters right now.
I know Nia's sister was upset but she was beyond cruel.
Alex was cruel as well. And even without her memories she seemed OOC when it comes to aliens. She remembers that J'onn is an alien and I know her mind is fucked right now but she should have more compassion to aliens than she had. I really don't like this new Alex. I want normal Alex back.
But this is why I like Legends though, conflict like this gets solved in one episode, it doesn't get dragged out.
I did however like Kara revealing her identity to Nia. Of all the people on the show who should know who Supergirl is, Nia is one of them. Especially since she's going to be a superhero herself.
And I'm really excited to see Nia as a superhero.
