A forensics team investigates the Unaspermer warehouse. Frank tells Lt. Bosslady that the Unaspermer got Wesley, and the janitor said that he took him off in a red Mazda with no plates. Lt. Bosslady calls in an amber alert. John shows Frank a newspaper clipping dated two days before the murders started, and Frank thinks that it sent the Unaspermer over the edge. John reads stuff from the Unaspermer's journal, which says that he will put Group Otto out of its misery starting at the source, which John realizes is Vitrochoice. John says that the Unaspermer was working his way through all of the donors, but then jumped ahead to Wesley. Frank says that the Unaspermer had to, because he couldn't get to the other donors. Frank then asks where this is going to end. Didn't John already answer that? Vitrochoice. Duh.

Frank and John blaze over to Vitrochoice. Inside, they find personnel scattered around on the floor. They hear a noise upstairs and head up to investigate. The Unaspermer has Wesley knocked out on a gurney as he smashes various trays and samples. Frank heads into the room with his gun drawn and orders the Unaspermer to freeze. The Unaspermer picks up a cranial drill and holds it to Wesley's head. He says that Group Otto wasn't a fantasy, and they used them to make Wesley. Yeah, tell us something we don't know, dude. Frank tells the Unaspermer to save himself. The Unaspermer doesn't care about saving himself. John uses a fire ax to take out an electrical box. The Unaspermer is distracted, and drops Wesley as Frank shoots.

Wesley is wheeled out by paramedics. Frank says that the killer was Chris Sherman, so the only one unaccounted for on John's list is William Sullivan. John asks if he looks like a William, and Frank says that he's more of a Bill. John already knows how many William Sullivans there are in the country (answer: a lot), and says that the only way to know for sure if that's his name is to account for every single one of them. Frank says that it's possible that the nurse who sold Wesley's mom the DNA profile was conning her, which would mean that John was never in Group Otto at all, under any name. Frank asks about Wesley. John says that he was given chloral hydrate, so he'll be fine, but won't remember anything. Frank says Wesley's mom is going to meet them at the hospital, and adds that he thinks Wesley has John's smile. Was Wesley smiling while unconscious? And wouldn't that be creepy? John says that there's still a chance that Wesley is his son. Frank asks if John is ready to be a dad. John says that he knows everything about facts, but nothing about being a dad. Frank thinks that's the smartest thing John's ever said. Ugh. What terrible dialogue.
