"YOU-" He stops short when he sees.. himself coming hurrying down the hallway to grab him. He- his body, rather- isn't exactly weak, but Loki has always been strong and that body has no problem slamming the bigger one against the wall. Out of habit, he expects pain, but is surprised to find that a mountain of rock hard muscles provides a decent cushion. It doesn't really hurt, but it's not important. Bigger issues are at hand.

"Who did you anger?!" he snarls. This wasn't his work and the only other possibility he can jump at is that Thor, in his luggish, dumb ways, insulted someone at the feast.
