Back in Los Angeles, T-Bag tries to use his prosthetic hand as an extension tool for opening the gate, only to have it hilariously backfire. His fake hand ends up on the ground, out of his reach. He ends up screaming in frustration. Upstairs, Self marvels, "For a little guy, he has some set of lungs." We find out that Bellick and Trisha are "all taken care of." Self continues, "I'm going to keep T-Bag in protective custody until we get Scylla, then I'm going to make someone at Illinois's [Department of Corrections] very, very happy. But more importantly, what the hell is that room downstairs?" Michael explains that the underground complex leads to the building where they can decode Scylla. (And hey! It happens to be General Von Baldy's office building. Small world, huh?) Michael's found a way to get into the unprotected substructure in what he promises is a 24-hour operation. Everything's coming up Scofield! He and Mahone want 24-hour access to the GATE building, and Mahone seizes on the idea that they can dress up as IRS auditors. Presumably, people will be too busy wetting their pants in terror to question that ruse too closely.
So, yeah, things are going wonderfully until a stray mobile phone just happens to ring near the guys, and Don Self picks it up. Gretchen says, "We have a lot in common ... open the envelope." We see that she's included more pages from that infernal bird book. Gretchen threatens, "I don't know what you've done with Bagwell, but unless I see him, you're not getting the rest of the pages." Michael grabs the phone at that point and demands to know who he's talking to. Gretchen says, "Hello, Michael." Aaaaand -- that's it! We have to wait a few weeks to find out if Michael's capable of leaping into a cellphone and coming out the other end to kill someone.
