Jack and/or Will has to die as a result of their stubborn pursuit of Hannibal. If it's one of them, gotta be Jack right? Will would have so much to recover from besides the mortal wound to the gut. But he is a survivor.

My first impression was that Alana is the only survivor. But judging from early reactions, others didn't see Will's last scene as the close to the character's arc like I did.
