Heck, the Green Lantern Corps might come to Earth in full force demanding Kara to be turned over since we know at least one of them fell by her and Brainiac's hand.I feel like season 3 is going to be focused on Lex solo trying to destroy Superman but I think defeating Brainaic will definitely put a target on Earth's back, whether it be from Darkseid...or people who have a beef with Kara.
