Back at Massive Dynamic, a very nervous Dr. Carson is wondering why Broyles and all the other agents are just standing around in his office rather than out looking for his kid. Broyles says he needs to be there for the call. Which conveniently comes right then. Olivia and Peter are back, and Nina's also in the room, when Carson picks up the phone and all the computers set up to trace the call start doing their thing. Tyler's on the other end, begging his dad to "give them what they want." Then Squinty gets on the line, demanding $2 million in unmarked bills, to be delivered near the Newark airport, at 5:00 PM. "If you're even a minute late, your son dies." Squinty hangs up before the trace can be completed. Olivia's confused: "All they want is money?" Carson says he can sell his house and cash in his stock options. By five this afternoon? Who's his realtor? "Massive Dynamic will cover any ransom," Nina cuts in. Broyles is agreeing with Olivia that it doesn't make sense. "Money's a distraction," she says with certainty. "They want something else." She tells Carson their next move: "We set a trap." Oh, a trap is being set, all right.

Walter rummages through a cabinet at the lab, even bouncing something off the camera lens at one point while he sings "Baa Baa Black Sheep" to himself. Peter and Astrid watch helplessly from a safe distance, wondering what he's looking for. "He just muttered something about my childhood," Peter says, as though that's unusual. Finally, Walter finds what he's looking for: an old teddy bear. Only it's kind of special, as Walter explains: "It generates white noise, which simulates the sound of being in utero." He turns it on, and it starts emitting a noise like an ultrasound. "A teddy bear versus mind-control spies," Peter says. "Bad guys don't stand a chance." Which would not have been as funny without Walter's wounded look. Although what I think that bad guys really need to be worrying about is how quickly the good guys seem able to shuttle between Boston and New York this week.

As we now see, as they have already returned to the greater New York area. Olivia is briefing a small army of tactical FBI agents who have assembled in a warehouse somewhere. Off to the side, the Bishops are watching. "This is exciting," Walter murmurs to Peter. "You think they'll ever give me a gun?" Peter just gives him a look like, "They better not before I get one." Olivia yields the floor to Walter to continue the briefing. He starts to explain about the headphones they've all been given, but he's taking too long, so Peter rudely cuts in, "The headphones will make it so the kidnappers can't control you with sound. Now put 'em on, we're going to do a sound check." They all do, and Peter turns the knob on the bear. Walter announces, "My son Peter's teddy bear emits--" Peter looks embarrassed, but the agents can't hear a word Walter is saying. Because of, you know, the noise-cancelling headphones. Peter gives Walter a wireless microphone, which is apparently also connected to the headphones. Through it, they can all clearly hear Walter tell them that their team leaders will each have a similar mic. "You will not be able to communicate with each other directly. All commands will come through the headphones." He warns them not to remove the headphones after the order has been given to put them on. "If you do, you may die a gruesome and horrible death. Thank you for your attention and have a nice day." Heh.
