I’m still pissed Mon-el suggested that Superman fights Rhea instead because he just simply does not believe in Kara, and has never believed in her.
You can give me the whole bullshit talk about how he loves her and doesn’t want to lose her or wants her to die but you do realize that Alex, Kara’s sister, loves her like no other could possibly love her and doesn’t doubt her, or tell her someone else should go fight?? Alex believes in Kara. Alex worries like hell, but she still believes, and doesn’t doubt her.
Heck, even Superman doesn’t doubt her. Superman didn’t go all macho and started crying about being beat by Supergirl. He praised her for it. He build her character up even more because of it. He believed in her too. He believed that she was worthy of being Earths champion. He was proud of her even.
Lena fucking Luthor believes in Supergirl. This isn’t because I’m biased because I ship Supercorp, because trust me, I know they won’t ever touch that and go there. But Lena Luthor builds the device to save humanity, and she believes in Supergirl so much, that she gives her the remote to activate it. She hands that choice over to Supergirl because she’s giving her the benefit of the doubt and giving her a chance to beat Rhea, because she believes Supergirl has the chance and could do it, and win Earth’s safety. But Rhea being Rhea, she doesn’t follow rules, and started attacking National City.
