Peck says Walter's asking him to just leave Arlette there, and Walter sadly nods. And FINALLY the tac team arrives, like maybe they stopped for a CIGARETTE they took so long, and Walter rushes to let them know that he's OK and to try to protect Peck, who takes advantage of the distraction to jump back in time again. Walter's yelling at the agents, "No, please! Gentlemen, please! Don't you see? We won't remember this! Don't you see? We won't remember anything!" So ... they should do what, exactly, Walter?

A cop gets out of his car to look at several dead bodies scattered around the sidewalk, and radios that he needs backup. The dispatch asks for his 20, and he's at 412 Inman St. Inside, Peck feverishly works on an equation on his blackboard.

And the Fringers are already trying to track down Peck, so this jump took him back only a couple of hours, since the Fringe team is just now discovering that Arlette Turling's cellphone signal is being handled by a tower near MIT. Broyles calls to tell them that Peck's back at his residence, which you can find easily if you look for the six corpses that are outside. "We have to take him down before he jumps again," says Broyles.

The rest of the Fringe team arrives as the tactical team sets up, not particularly worried about tipping Peck off this time. He's watching from a second-storey window in his apartment.

Then he sits down at his desk and takes out a piece of paper. He's very calm about putting on his glasses -- not in a hurry, despite the SWAT team trying to bust into his place. It's slow going for them, because he's piled all kinds of furniture behind the door. At least the tac team set up RIGHT OUTSIDE this time instead of three miles away. He scribbles something down on the paper, and puts it in an envelope that he marks "Carol Bryce -- MIT."

Meanwhile, snipers are getting into position on a nearby roof. I'm no SWAT team coordinator or anything, but I probably would have had those guys in place before I started battering the door down.

We can see Peck -- still writing his damn pen pal at MIT -- in the sight of one of the sharpshooters, who radios to Broyles that they've got the shot. "Take it," says Broyles. Walter looks a little distressed -- although in this version of the Choose Your Own Adventure, he didn't wind up having his heart-to-heart with Peck.
