John goes back to the institution and tells the nurse that Dr. Jansen is now the main suspect, because they think he's been exacting revenge on the twins' behalf. John tells her that there is a third potential victim, but that he's camping at Olympic National Forest. Police are searching for him in the northwest basin, but John thinks he's in the southeast basin. John asks Nurse Miller if there's anything she can tell him about Jansen's whereabouts. Nurse Miller doesn't know. John tells her that Bowen is being released today. Nurse Miller thanks him, and John notices her missing fingernail again.
Out in the woods, a shadowy figure approaches the campsite of Peter Druzinski. Thankfully, Peter has labeled his canteen with a big piece of masking tape and a marker so that we know that it's his site. The shadowy figure is revealed to be Nurse Miller, who busts out a large butcher knife. She approaches Peter's tent and then just starts hacking at it indiscriminately. That doesn't seem like a good way to chop someone in half. John pops out from behind a tree and surprises Nurse Miller, who throws the knife at John and runs. Either he's really slow, or she's really fast, because she manages to get into her car and peel out before he catches her. John runs over to his own car, but an RV blocks it in. John runs over to a field where there is a convenient hang glider and...I just can't finish that sentence. Why was there a hang glider? The helicopter in the first episode wasn't enough? Anyway, John hang-glides down the mountain and lands on top of Nurse Miller's car. Oh, this is so dumb. Nurse Miller swerves all over the road and then crashes into a ditch, and John is thrown onto the ground.
Lt. Bosslady walks into the police station and asks John why he didn't call the cops. Because thus far, the cops have proven themselves both stupid and useless? It's not so much that John's a genius as that the cops are really, really dumb. Frank asks John to recap how he solved the crime for the benefit of the slow people in the audience. John explains about the hereditary condition that Nurse Miller, Daniel, and Polly all had that meant they were missing fingernails. Frank -- a little slow on the uptake -- realizes that Nurse Miller is Daniel and Polly's mother. John says that she gave them up as a kid and figured they'd always have each other. Lt. Bosslady fills in that Nurse Miller tracked them down and realized that they were split up, and it made her crazy.
