We already know from the first trailer that Thor will come to Loki for help in defeating a common enemy, and it seems that the two will work together -- but will there actually be any true brotherly love there? While speaking to Screenrant about it Chris Hemsworth is careful not to give too much away as it pertains to the plot of the movie, but it definitely sounds like it might not JUST be a case of the enemy of my enemy is my friend; Thor may still have some "empathy" for his trickster brother after all.
“I can’t say too much, but I think in the comic books you kind of roll your eyes sometimes at the amount of times they’re back to being best friends. And so we wanted to keep in mind, Loki did just try to kill you for the seventh time – and Earth. It’s a big war, and what have you… Maybe there’s something we can maybe, [CHUCKLE] … We have a common need or something which, you know, that would, well… [laughs] You know the scene in Avengers when Thor says ‘careful how you speak. He be crazy but it’s my brother,’ kind of sums it up. Yeah, he’s a screw up but he is my brother. I don’t think they’re back to being best friends, but Thor’s at a loss about how they got to this point, ’cause for him, I think [treachery] stuff came out of nowhere and I think that in this film [Thor] certainly can acknowledge now with a maturity that he should have been more aware of Loki over the years and where he was positioned and all of this, and why maybe that led him down a certain path. I think there’s maybe an empathetic view for Loki that no one else can have because they’re not bound by blood, you know.”
