Robb will be dragging Grey Wind and the rest of his family plus any other stragglers along to the palace. He'll be that one dumbass who makes sure all of them are safe first before rushing back in there to bring in more people, gdi. He's going to be helping with relief efforts and at some point will be finding a place to stay during all this, so hey, bright spot in all the suckage. And then after that, he's going be seeking out his loved ones to cuddle with. Stark cuddlepiles yes.

Bucky will also be a stupid dumbass who drags as many people as he can to the palace and then comes back for more. He'll be joining the relief efforts afterwards, helping rebuild damaged structures, and then he'll come along to the Mirror Lake thing. And probably die for the destructive visions he's going to get because he's had it easy for long enough. Once he gets back to the city he'll also be joining the cuddle parade, woo.
