Man, this sh*t can go either way. What if at the end Skylar k!lls Walt? Maybe she convinces Jesse or some sh*t since Walt told her about how he wanted to k!ll him at one point and put a gun to his head? So she'll feel that maybe Jesse still has an urge to k!ll him but he's afraid like she is? Nobody knows Walt more than she does, so she can set it up for him to get k!lled. Jesse might want to get out and go on with his life with his new girl and her kid, you can tell he's a simp for females.
Walt will most likely k!ll her with the ricin ("nothing is going to stop this train"), there is a reason they made him save it and showed him taping it to the back of the cover. It's going to come into play again. They've always went out of the way to show emphasis on that plant in the backyard. So maybe that's going to be the end all of everything, is that ricin. When Jesse was convincing Mike to not k!ll the other chick, Walt looked to be in deep thought, probably comparing this chick and her being a threat, to his wife being a threat and maybe needing to k!ll her. I'm sure he knows she's thought about k!lling him or wished death on him cause of the "waiting for the cancer to come back" comment, that sh*t was a pretty fu*ked up thing to say.
All I know is this sh*t is getting really good. Cant wait to see how they finish this show off.
Jesse broke up with that girl earlier this season, the episode where they make the first batch of meth in the bug home. He was telling Walt because he thought Walt cared since he was talking about her when they were waiting for the Meth to cook. Said something like, "I ended it, I just had to you know what I mean?" but Walt was asking him how he felt about getting less money, then left some cryptic message about how Gus k!lled one of his henchmen because he "flew too close to the fire."
I still think Skylar k!lls herself, Walt accidentally k!lls her, or Mike k!lls her. Either way I'm almost positive she's going to die (according to the very first scene of this season.) Walt uses her maiden name on his fake identity. When he orders eggs and bacon he does exactly what Skylar used to do and makes his age "52" (a year later from this past episode) out of the bacon. It could be that she leaves, but that would be entirely less dramatic and I don't think the writers go that way, I think it's safe to say she's going to die.
It's setting up like an all out war between Walt and Mike/Jesse. Jesse is going to find out about Walt poisoning the kid from Saul (the only other person who knows.) Then it's really on. Mike is waiting for the opportunity to murk Walt, but he's waiting so he can make his money back and kept his men from snitching on him.
