We should all have a sister like Alex. She snapped Kara out of her depression. 5 episodes later Kara does the same for her. This show made a mistake by putting this relationship on the sideline.
Kara is right Alex needs to stop comparing her to herself or others about being human part like just let her grieve in her own way and give her own space it never ends well if she doesn’t
Alex thinks she’s better then Kara or something like seriously leave Kara alone cuse Alex keeps complaining about a bar party or something and she wants Lara to show up there like forcing her
I think you guys are missing the point of what Alex was doing in this scene. It's basically the same thing Kara does for Alex 5 episodes later. She wasn't telling her not to grieve, she was telling her it's okay to be sad but that Kara needs to let herself be sad and not close herself off.
