This week on Prison Break, members of Agent Self’s handpicked group went to Las Vegas in pursuit of the fifth Scylla card. Sucre, Sara, Roland and Lincoln all went to Vegas while Michael, Bellick and Mahone went searching for T-Bag. T-Bag, who was threatened and tortured by Gretchen, is also trying to get Scylla. He managed to trick Bellick and took Michael, Mahone and Bellick hostage before Mahone escaped. Michael had to help him decode Whistler’s Bird Book. Mahone immediately found Self and told him what happened, and they rescued the group while trapping T-Bag underground. But Michael later found out that T-Bag was working for Gretchen, the woman who held Sara hostage, and he was threatened to get T-Bag out of the place he was trapped.

On the brink of retrieving the information of yet another one of the six cards that hold "Scylla," former Federal Agent Alex Mahone's temper got the best of him when he punched an officer and got himself arrested trying to retrieve Roland's WI-FI device. He went to jail and Agent Self's handpicked group of people chosen to take down The Company became shorthanded. There were mixed feelings as to whether or not it was worth it to try to break Mahone out of jail, but they ended up making the attempt anyway. Speaking of Mahone, he and Wyatt, the man who killed his son, had a heated phone conversation which might be William Fichtner's best scene on “Prison Break” this season.
