So 4 months till the final season of Breaking Bad, anyone think this final season will be as explosive as the last? Also will Walter survive?
No, Walter won't survive (unless they decide to make another season after the "final" season...) The way I see it, there are four possible endings:
1) Walter dies of cancer (this is the closest that the show would be able to get to a "Walt gets away with it" ending)
2) Mike comes back from Mexico and kills Walter (he has all the reason in the world, after all...)
3) Jesse kills Walt (perhaps after finding out about how Jane died, or about what happened at the end of season 4)
4) Hank arrests or kills Walt (Hank has been treated pretty badly throughout the show. This would throw him a bone at the end of the show, sort of, in that he finally catches Heisenberg).
Then again, I could be, and likely am, entirely wrong. I have no knowledge of the future.
