Push off a cliff - ODIN at least in my head this was supposed to be Avengers, not the whole MCU... Nick Fury (the manipulative asshole)

Frick frack - Natasha (for obvious hot redhead reasons uhm...)

Marry - Clint (my underestimated bb)

Set on fire - Tony (honestly only to see Dum-E going all firefighter on him, that's so funny XD)

Wrap a blanket around - Loki (yes, that was kinda... yeah. Sry not sry tho. ;D)

Be roommates with - Darcy (has the advantage of getting to know Thor and Jane a bit better, but Darcy is my fav, hands down)
