Why am I returning to this one? I just browsed through a recap of the episode in TV.COM, and it was pretty funny. I didn't read everything, but here is the closing statement. You can read the rest in the link above.
Some old guy, obviously of a higher rank than the Colonel, so I'll dub him General, or Genny for short, enters the Yard. He marches straight to Michael and says that there have been two escape attempts since Michael arrived. Perhaps SONA isn't the best place for Michael so he's led through the front gates. Bellick, T-Bag, MBBM and Whistler are all, "Wuh? Does this mean I'm no longer part of the supporting cast? I gotta call my agent!"
