Pretty sure Loki instantly iced the room for protection and blocked other from getting in? Laufey i believe catches up to Winter Solider and ices him in place, and Loki appears once he sees Tony is ok? Maybe he didnt see Tony was fine, i dont remmeber He wants to take revenge but Cap comes up and begs him not to because its Bucky. I think Bucky gets taken to Asgard after that but they wouldnt let Steve come?
Any help would be much appreciated!
