Loki :( punching me in the face would have hurt much less than this <--- I KNOOOOWWWW, RIGHT?<<<Guys, he's just being manipulative so Thor doesn't destroy the Bifrost. Loki wants to use it to destroy Jotunheim.
I think he thinks it's funny how NOT original Volstagg is (and that it's darkly funny that things haven't really changed). Because his reaction to Sif vs Volstagg is actually very different. -- I feel bad for Loki.
