"There were times," Walt continues, "where I was sure I was done for." Self-mythologizing has never been too difficult for Walt. "But then someone or something would come through for me." He turns around towards Skyler, purposefully oblivious to her strange behavior, and reminisces about her taking care of him after his first chemo treatment. She never turns to look at him though, instead staring into the glowing blue of the lit pool water, until she finally starts to wade in. Marie is the first to call out to her, but Skylar's not stopping. Hank and Marie panic that she's not emerging from the deep end and by the time we cut to a POV from the pool, Skyler is almost touching the bottom. Her blue skirt is flowing in the blue water and soon enough Walt dives in to rescue her, a devil descending from above.
After the break, Nervous Lydia is jittering around the warehouse, trying in vain to find the switch that opens one of the loading-dock doors. Once she does, she finds Jesse on the other side and even though he insists he's "the guy" Mike sent, Lydia stammers and demands that he tell her Mike's last name. I really feel like "Ehrmantraut" is having its moment in the sun this season. Anyway, Lydia's like, "Sorry, not sorry. For all I knew you were one of those undercover cops they send into high schools." HA! I'm really coming around on Lydia, you guys. She leads Jesse to the rack where the methylamine barrel sits on the top shelf. As Jesse operates the forklift to bring it down, however, Lydia spots something on the bottom of the barrel and freaks. Looks like something has been stuck with putty to the barrel.
