Ugh... I'm kinda yanked that Mike used a plastic tie wrap to restrain Walt. Mike's been around Walt long enough to know that Walt is as slippery as they come, very intelligent and resourceful and a clearly desperate man "at the end of his rope" that is going to do whatever it takes to keep his part of the methlymine.
Didn't Mike also have Lydia in metal handcuffs the very last episode? (when they forced her to call the DEA and read the script) He just left those at home this time?
To have to leave him alone and restrain him with just one plastic zip-tie... Because of the half and full measures talk, how he's never going to do that mistake again (oh really?), because he's seen what Walt can pull off in order to survive. Not going to buy that he didn't have any cuffs on him, the whole thing was planned, Mike should've just gotten a couple of cuffs (that he has used before), and make sure Walts both hands were tied. Not just wrap his wrist into a radiator with a fuckin' PLASTIC ZIP-TIE!
Ohwell... The dinner scene was hilarious. Jesse's face when Skylar mentions her affair...
