A helicopter flies through the night sky. In a car, Digger and John discuss the case. Digger thinks Pesco is "cold-filtered," and John wonders how many people Pesco has killed. The helicopter closes in on a vehicle. John asks Digger if it's possible to block out memories entirely, and Digger says it is if you drink enough, which is why he owns a bar. Well, that's healthy. Some cop cars pull over a van. Ruiz gets out of one of the cop cars and orders John to show his hands. Ruiz walks up to the driver's side and finds -- the lady that John bumped into during his escape earlier. He orders her out of the car. Ruiz throws her up against the hood and pats her down, and finds his cell phone. Oh, that John!

John and Digger enter the sewers (a.k.a. the set of Dark Angel). John spins some theories about why he and Pesco have the same brand. John says that there are a few things Digger doesn't know about him, starting with the fact that just before he came to the bar for the first time, he woke up naked on an island. Digger reveals that Karen already told him the whole story. That Karen has a big fat mouth. Although she hasn't been around much lately, so thank God for small favors. Or large ones. John wonders why Digger didn't mention that he knew, and Digger says it wasn't any of his business.

They continue in the sewers until they come to the place where John originally found Pesco hanging upside down with his head underwater. Digger says that when he conveniently used to work in the sewers, he knew not to open the drainage gates, because you can't close them once they're open. Digger wonders what Pesco would have done if John hadn't arrived in time, or figured out the clue at all. John says Pesco would have drowned, and Digger suggests that Pesco had a backup plan. Digger thinks that the cops searched the place "upside down," which makes John realize that they probably didn't look underwater. John recalls where Pesco was hanging and plunges his arm into the water. Or sewage. Ew. John pulls out a grate, and then a "closed-system rebreather." Which Digger immediately identifies. From his days when he conveniently worked as a scuba instructor, I'm guessing. John says that the oxygen tank could have kept Pesco alive for eight hours. John pulls a pink envelope out of the tank, opens it, and shows Digger the front, which is a picture of a ghost.
