Plot summary
General Zavala, the new chief guard, tortures Scofield to talk. Mahone is returned to Sona and he continues struggling with symptoms. Bagwell and Whistler agree to get Sammy killed. The former offers Mahone drugs in exchange for killing Sammy, which he refuses. Meanwhile, Sucre has an apparent argument with Lincoln, prompting Anthony to have the former spy on Lincoln; but the argument is revealed to be a ruse to get Sucre inside. Scofield tells the truth to Zavala, who forces Whistler to reveal Anthony's true name, Gretchen Morgan, and her whereabouts.
Zavala arrests Morgan and starts torturing her, with Scofield promising her revenge for Tancredi. One of Sammy's men challenges Bellick to the ring, which the latter wins by soaking his hand wraps in acetone to intoxicate his opponent. Bagwell finds out about his trick. Morgan agrees to take Zavala and his soldiers to L.J.'s location, where she manages to free herself and kill them. Scofield and Whistler are returned inside by the new chief. Augusto tells Sammy to move on Lechero and open the last package, which contains a gun.
