Yeah, this is why Peter's not helping out: he's stalking Tess and Michael again. Michael comes down the steps out to his car, and Peter walks up behind him, and spins him around into a sucker punch. Michael gets an elbow in, but then Peter makes with the kung-fu and kicks the crap out of the guy, all Sonny Corleone on the sidewalk. Peter picks up the guy's gun, which got knocked loose, and points it in the guy's bloodied face. "If you touch her again, I'll kill you," he says. He walks away, taking the magazine out of the gun and throwing the pistol into the nearby trash.

Over at Boston Federal Building, agents are trying to find the mystery man by using facial recognition software and passing the composite around Young's apartment building and his office. Olivia's working the phone herself when Broyles stomps up and delivers a stack of files. "From Nina Sharp. Mark Young's projects," he says. They share a moment of surprised victory, and I'd like to point out that it's kind of funny that they just take it as a given that Nina hasn't held anything back.

She starts going through the files, but something twigs when she looks at Young's business card, with the phone number 1-877-8-MSSDYN. Even though we've been told she has this amazing memory, she has to dig for Young's day planner to find the word MONARCH again, and makes a phone number out of it, and calls. Here's hoping it's a local call, otherwise she's going to have to figure out the area code, too.

A man answers. Somewhat startled, Olivia says she's calling on behalf of his long-distance carrier. "I'm not interested. I don't want you calling again. So take me off your list, OK? Hasta luego." Closed captioning, instead of "hasta luego," says, "'cause I don't mess around." Olivia flashes back to the memory where the guy said exactly that, and excitedly hangs up the phone. "I need this phone traced. This is our guy," she says. Charlie asks how she knows, and she says she recognizes his voice. "You recognize his voice?" but that's another one of those "long stories" that Olivia doesn't like to tell her fellow agents. They trace the phone to a land line that's been forwarded to a cell, which is currently in transit on Route 3, heading to the Lincoln Tunnel.

So, based on, "I recognize his voice," Olivia and Charlie are part of this tactical team that's going to take down George Morales, 43, who bought a plane ticket this morning to Sao Paolo, out of JFK. "According to NCIC, he's a black market trafficker, high end," says Charlie.
