The end really was savage and heartbreaking for Walt. I wonder what he's going to do; flip out, maybe go after Ted or just go into a reclusive catatonic depression.
Jesse had that look in his eye that he is now educated enough and determined to produce the same quality of product. The thing is that he doesn't have the Gustavo connection; Walt does. Even if he produces he won't be able to move large volumes unless he gets hooked up.
I don't know what to think about the whole Gustavo/Salamanca bartering for Walt's life deal. Maybe to keep Walt alive Gustavo is going to have to let them in on the operation or something. That warehouse looks like it's going to come back into play as well. Gustavo seems determined that Walt is going to continue doing business with him, whether he wants to or not. Perhaps with the recent Skyler thing Walt decides to just say "fuck it" it and go back to doing business.
While Gustavo is professional he is starting to have a calm, but ruthless undertone; saying things like "once our business is done he is of no concern to me". Walt is getting in ssooo deep but he doesn't realize it yet.
Hank is really losing it too. You just know at some point he's going to get twisted into all of Walt's business too. They're both working at the top levels of the two opposing forces (DEA vs. cartels).
I am so full of suspense as to what the next episode will bring. It's complete torture to have to wait a whole week.
One thing is for sure; Skyler is a ruthless, evil, heartbreaking bitch. I hope she gets her comeuppance.
