All right I think this is my shortlist for dead pool

Mormont
Shae
Talisa
Theon
Brienne

It appears to me that Rast is being situated to contrast Snow. So when Snow returns to the Wall, it could be that Rast is the head of the Night's Watch because Mormont is dead

If Shae's purpose is to further the Tyrion story, she's deader than a doornail. It's just a matter of when

I have no idea how Talisa dies, but she's not important at all and if she died it would just fuel a plot

Theon is sort of a long shot, but he has no home and he's the victim of everything. The Greyjoys have a role in something, but how is not yet determined. It could be that he dies and they get really upset at his killers

Outside of the potential foreshadowing that Brienne fights against Stannis, she is highly expendable. She appeared out of nowhere and can die out of nowhere. The Boltons are taking her and Jaime, and she's not aligned with their desires at all


Also I would adore the Tyrell women turning on Sansa and telling Teh Joff that she called him a monster. Would teach her some valuable lessons to have her pampered ass in a dungeon for a while
