I am.
I'd like to know how the kid got a hold of Jesse's ricin-laden cigarette. I'd have to rewatch the last episode to be sure, but I had the impression Jesse had the poison with him when he went to work, ruling out the possibility that the boy swiped it from him. (Besides, that kid seems awfully young to be interested in smoking. Plus, his mom smokes, so why not steal from her if he were so inclined?) I tend to believe that black guy that works for Gus and who hovers over anyone in the lab is responsible.
Also, Gus is smart. No doubt about that. But him avoiding his car borders on fucking clairvoyance.
I also can't help but to wonder if Hank, who's a bit of a Gary Stu, will figure out that his associates' sweep of the laundry place was incomplete. After all, what use would Gale's awesome air filtration system be ABOVE GROUND?
Saul split town, so he's probably a non-factor for the remainder of the season. But what about Mike? Gus' doctors did patch him up, but only after they went to work on El Jefe. Plus, after seeing Victor get his throat cut, even someone as loyal as Mike would have to realize his number could come up at any time. And call me crazy, but Mike seems to obey a code of honor Gustavo doesn't; e.g., hogtying, gagging and blindfolding some tweeker at Jesse's place but not killing the guy because he was no liability. Gus threatened to kill Walt's *infant daughter*, who is as far removed from a liability as one can get.
One other thing: is it me, or is Walt's wife the sweetest thing you ever saw? No, she ain't Jessica Alba or Kate Beckinsale, but she oozes estrogen and is tirelessly supportive of her gimp hubbie, in spite of how mean he can be to her. I'd take her as a wife over some gorgeous ice princess every day of the week.
