Tom Hiddleston said that Thor and Loki are “brothers and friends and allies” and “two halves of the same whole” and “born to be together“ and I think I might have actually died a little listening to him speak those words.
“Loki, I thought the world of you. I thought we were going to fight
side-by-side forever, but at the end of the day you’re you and I’m me
and… oh, maybe there’s still good in you but… let’s be honest, our
paths diverged a long time ago.”
