What are the things you expect the most from next week's season finale and the show's Season 4?
I think that either this season is going to end with Jesse's death or a twist that postpones that from happening for at least a while like Gus getting killed or something. At some point, Walt will give into Skylar's involvement in the business but if Walt decides not to let her have any part of it after the events of last episode, then I think Skylar will scheme her way in.
In Season 4, I see a storyline for Walt Jr. in which he breaks bad like his parents. Either he becomes a drug addict or a drug dealer or does something that pushes him over to the dark side. Hank will continue his pursuit of Heisenberg and find out that it's Walt. Then he faces a dilemma about whether to turn Walt in especially after finding out some of Walt's drug money was used to pay his hospital bills. Marie will confront Skylar about her knowledge of Walt's criminal dealings and a rift will develop between the two sisters. If Season 4 is the final season, Jesse will learn the truth about Jane, Jessewill die at some point possibly by Walt's hand, andI see this show ending inone of two ways: either Walt dies or he lives but finds himself in a bad situation. Either way, I don't see Walt having a happy ending. Maybe anambiguousending like the Sopranos.
