So the episode starts with Michael and Dr. Sara merrily burning off an entire Triassic age's worth of fossils in their SUV as they sigh over how happy they are. Michael promises, "Some day, weeks will go by -- maybe even years -- when it won't even cross our minds." Dr. Sara adds, "We'll come home and talk about work. And what we want for dinner. Movies --" "Nursery schools," Michael interjects. Dr. Sara is like, That's right -- I AM pregnant! and she gets a look of bug-eyed panic for a moment before remembering that assembling the crib will be no problem thanks to Michael's supergenius spatial skills. The upshot of this scene is they're both really looking forward to family life.
Then Mahone calls, all panicky, and Michael tells him he'll just have to trigger the detonator manually. Mahone swallows his panic and manages Christina's temper tantrum while also managing to launch the bomb. He really is cool under pressure when he's focused. Christina eventually concludes that Mahone's lying about Scylla and orders Slick to "kill the junkie." Unfortunately, she doesn't know that Mahone's had the same One World Conspiracy combat training Slick has. Within seconds, Mahone has armed the bomb, kicked both evildoers to the ground and taken shelter with Linc. And the bomb goes boom.
As does General Von Baldy's temper when he comes back to the loft, and discovers Dr. Sara gone. He's revived T-Bag for the express purpose of berating him, then prepares to kill him. But first, an employee evaluation: "Men in my employ anticipate. They cover their bases. They refuse to fail, which you seem to be with unyielding consistency --" And we are all saved by the bell. It's Dr. Sara's phone. T-Bag answers and Sucre confusedly asks, "Who the hell is this?" Where are his phone manners?
Well, they're not in Miami, which is where C-Note and Sucre happen to be now. T-Bag spins a yarn about how Michael, Dr. Sara and Linc are all being held hostage by evil mastermind Christina Scofield, and if C-Note and Sucre meet him in a certain park at a certain time, he will give them the whole sad story: "We should get together and pool our resources." T-Bag manages to bargain for his life by pointing out, "I do have a sit-down with Scofield's friends in an hour. You got no better hand, General."
Michael and Dr. Sara have just swung by Christina's office to behold the carnage. They also pick up Linc -- who, even with his collapsed lung, manages to insist, "No hospitals! Hospitals mean jail!" -- and Mahone. The latter is pretty sure that bomb took out Christina and Slick. However, Christina had pulled Slick on top of her in the face of the blast, so we see now that her fingers are twitching. OF COURSE.
