Good finale. Not at all what I expected or predicted. Walt really did poison the kid. I still don't see how he managed that, but it all fits into place now. The gun spinning towards the plant; Walt being AWOL for most of the day; Jesse getting his cigarettes lifted off him and Walt being prepared for a confrontation with Jesse.
It's almost too neat, but Hector really was the chink in Gus's armor so I give the writes props for being consistent with that.
Damn, though if anyone remembers Walt being at the rest home he's right back in fire.
Also, Walt's got no money now, so it won't be long before he gets entangled in that shit again. Does Jesse still have money?
Walt still has paper.. he just didnt have enough to "dissapear" his whole family.
