And people keep saying he’s the bad guy….so, if that’s true why is he telling his brother about that?
I completely agree. Yes, he’s the bad guy and he doesn’t want the bifrost destroyed until it’s completely erased Jotunheimr, but I think by that point it had probably killed most of the frost giants so I feel that this really, truly is Loki sorta looking out for Thor in a weird way. He’s jealous of Jane but he’s happy that his brother has found love. He’s such a complicated chap.
