SPOILER THOUGHTS ON LAST EPISODE.......
Walter is a complete faggot now. He alienated Jesse, and killed Mike. He is also training crazy Todd. Everything Mike told Walt before he died was the truth. I'm still trying to tie in the season opener of why walt had the chopper. At first thought was Mike didn't die, because Walt didn't finish him off, but that would be unbelievable. Really even those people in prison don't have much connection to Walt now Mike is dead, so I'm not sure why he needs to off them all.
The show fore shadowed when Walt said no one else will die, and Jesse said thats not true. I liked Mikes character, he was the voice of reason in many ways. I think Jesse and Walt some how go to war. I think Jesse is more loyal to Mike then Walt. This is going to turn into a giant cluster fuck. Todd is a complete tool, and is going to be Walts muscle.
