Definitely a great episode last night. Plenty of things that need to be tied up, but Walt did get the bug out of Hank's office...........which I thought Hank would eventually find.
My theory is that Jesse and Skylar will team up against Walt at some point. They threw each other a look at the carwash that made me think that. I think Jesse recognizes how unhappy Skylar is with everything, and now that he and Walt had a falling out he has more motivation to get back at him.
In that case, I might actually root for Skylar to win (previously unthinkable) so long as it means Jesse and Walts' kids end up with the money.
I don't think so. His ID had his real birthday, and his fake last name was Skylar's maiden name. I think he custom-made those for himself, likely using the guy that Saul told him about who can make people disappear... remember the business card that Saul gave Walt, when Walt wanted to make his family disappear before Gus came to kill them? It had something to do with vacuum cleaner repair, I think. I bet Walt still has it and uses it in desperation.
Forgot all about that.
