One commercial break later, the hostages are still being transferred to the basement. Robber #2 tells Prescott they're running late. "Should I call the boat?" he asks carelessly, right in front of Michael. This isn't a conversation Prescott wants to have in public, so he tells Michael to join the stream of hostages heading downstairs. Michael complies and grabs his kit, falling into step with Bly. Since the escape as originally planned isn't happening, he's working on a plan B. "I need your help. Do you trust me?" he whispers. By now, Bly does. "I need you to collapse in that doorway. Sell it. Buy me time." Bly goes for it, and Michael crouches over him, saying he needs a couple of minutes to keep Bly from going into shock. "You have one," Prescott says, and goes on ahead with the others. Which leaves Michael to get back to his hidden Ethernet phone.
In the alley outside, Sam takes the call from Michael while Fi's taping a big cross on the outside wall. Lucky for both of them it never occurred to Prescott to wonder what the hostages planned to do once they got to the next room. "Forget the escape plan," Michael tells Sam. "Prescott's moving everybody downstairs." He tells Sam that the robbers have a getaway boat waiting, and he wants Sam to find the robbers' walkie-talkie frequency. It's not clear what Michael plans to do with that information when he has it, but he probably figures you never know what might come in useful. In the doorway, Bly hisses that the robbers are coming back for them, so Michael hangs up and helps Bly to his feet, grabbing a rubber doorstop as he does so. As they walk past the elevator, Michael VOs, "Elevators have so many safety devices that they're easy to sabotage. Disable any part and the entire system shuts down." And apparently all it takes is shoving a doorstop between the sliding door and the frame, which Michael secretly does. A broken elevator isn't going to blow the whole robbery, but considering Michael's scattershot approach to his secret sabotage, he's going to end up running a pretty decent average.
Back in Fi's Saab, she complains about how they're going to locate one getaway boat in Miami. "I still think we should set off the charges, blow a hole in the wall, rush in. Beats waiting out here." Fiddling with a walkie-talkie of his own, Sam says, "Yeah, that's great. Let's get Mike and the hostages killed because you have the attention span of a three-year-old." It's the delivery that makes it work.
