Walt and Jesse return to dispose of two bodies in the RV, but discover Krazy-8 has disappeared. Walt finds a barely-conscious Krazy-8 wandering Jesse's neighborhood and brings him back to Jesse's house, restraining him with a bicycle lock in the basement. Walt procrastinates killing Krazy-8, instead providing food, water, and basic care. Skyler grows suspicious of Walt's recent secretive behavior and questions him during an ultrasound appointment about a mysterious phone call with Jesse. Walt lies that Jesse sells him marijuana for his cancer symptoms. Skyler visits Jesse directly and threatens to call Hank if Jesse contacts Walt about drugs again. Jesse attempts to dispose of Emilio's body using hydrofluoric acid as Walt instructed, but ignores Walt's advice to use a plastic container and instead uses his bathtub. The acid eats through the bathtub and floor, creating a gruesome mess of dissolved remains throughout Jesse's house. Two children playing in the desert discover a gas mask that Walt and Jesse accidentally left behind at their cooking site.
