Deleted Scene 5
Two things I love about this:
a) that Loki has absolutely no doubt that even handcuffed he can get that dagger through the guard’s back at twenty yards, and
b) the totally whiny ten-year-old “But I WANT to! You suck!” expression when Thor says he’s not allowed to kill anyone.
Not to mention c) the look on Thor’s face when he’s plucking the dagger from Loki’s recalcitrant hands, no, Loki, we said no killing, don’t go murdering the staff again, I swear if Mother were still alive I would so tell her. He’s not even mad. Loki is so predictable, you wonder how he got that reputation of being a mastermind, he’s basically a two-year-old in a permanent temper tantrum, probably because someone tried to give him a haircut.
Also, he totally pouted as a child.
