Jesse returns to Fi, telling her what he learned from "Ichabod Bolt." But before they can follow that up, she gets a call from Sam and Michael, who are busy with Walt wrapping up that TV-bomb in duct tape and plastic trash bags next to the pool. They need her help triangulating Dennis's position using the signal from the bomb's remote detonator. As Sam and Walt lower the TV into the pool, Michael suggests they can maybe use his mom, too. "Jesse will do it, I'll call you," Fi says and hangs up. Jesse refuses to get involved, until Fi says that while they lied to Jesse about what they did to him, they didn't lie about who they are. Hence this operation to catch the South Beach Bomber. "Ah, son of a bitch," Jesse sighs wearily.
Inside Walt's house, Michael's got the laptop and cell phone set up, and it's five o'clock. Right on time, Dennis calls to tell Walt he's the guy who killed his boss, and he wants Walt to turn on the news. Walt lies that he did, and the pool explodes, thanks to the flat-screen depth charge they sank into it. Sam, Jesse and Fi, positioned all over town, are able to triangulate Dennis's position: right outside Fi's house. She goes out the back window jus before Dennis stomps in.
Michael and Sam meet up with Jesse and Fi on the street outside Fi's house. Sam tells Jesse it's good to see him. "You really want to have a reunion right here? Seriously?" Sam lets it drop. They assess the situation: there are still four more Dennis-bombs all over town wired to hair-trigger radio detonators. Michael volunteers to go in alone and let his friends shoot at them so Michael can bond with Dennis under fire, but the cops are showing up, so that's not going to happen. Even so, Michael's messiah complex gets an assist from Sam, pointing out that if the cops get Dennis he'll never give up the location of the remaining bombs. Michael gently tells Fi it's okay and heads off.
In character as Gordon, Michael enters Fi's place and tells Dennis -- who's holding a fresh bomb -- that the cops are coming and they have to leave. He claims that he followed Dennis, and "ended" the jogger who saw Dennis break in and called the police. "I'm like you now," he says proudly. Dennis is pissed off at how much heat Michael's brought down. Meanwhile, outside, Jesse's worried about all the cops showing up with their radios. "One burst of static on the wrong channel," he frets. The team spreads out and starts telling the cops to shut off their radios. Inside, Dennis is watching the unfolding scene while Michael VOs about how zealots think they have something to teach the world. "Dealing with a fanatic, then, is often just a matter of being a very good student." Dennis sits down and arms the bomb he's been holding and starts ranting about how this is only the beginning, and others will follow in his crazy footsteps. Michael pretends to know what Dennis is saying: "I can walk out of here like your hostage, the cops won't even bother me. I can detonate the devices!" Dennis acts like that was his idea all along. Michael keeps selling it, getting Dennis to agree to tell him the addresses.
