Complete story — includes the ending
Lydia offers up her own employee to the DEA and Mike offers her a replacement: Jesse. Together, she and Jesse spot a tracking device on a barrel of methylamine. Mike is skeptical that the tracker was planted by the DEA because of its crude placement, and believes that Lydia placed the device herself to get out of their deal. Hank receives a promotion to ASAC. Skyler's depression and frustration begins to grow more severe. During a meager celebration for Walt's 51st birthday, a fully-clothed Skyler steps into the pool and slowly submerges herself before Walt pulls her out. Walt then learns that Skyler has asked Marie and Hank to look after the kids until her issues with Walt are resolved. Skyler threatens to further harm herself if Walt brings the kids back home, but he belittles her plans and threatens to have her institutionalized. Realizing there is no way out of her situation without hurting her family, Skyler tells Walt that her only option is to hope that Walt's cancer will come back and kill him.
