The geniuses walk back out into the station. John asks what the story is on Zeke Pepperfield. Dr. Elvis says that Pepperfield founded Group Otto. Frank pipes up that Pepperfield is "the Sy Sperling of sperm" because "he's not just the founder, he's also a client." Dante says that Pepperfield turned in his medical degree and bought a diamond mine in Prairie Creek, Arkansas. Dionne adds that everyone knows the purest forms of diamonds are found in South Africa. John contributes that 98 percent of diamonds found in Arkansas are industrial grade. The geniuses list off all of the uses for industrial grade diamonds, like, how annoying would it be to hang out with this crowd? Dr. Elvis supplies, "Surgical blades." John adds that they're used on "diamond-tipped cranial saws." Frank figures out that John just named the murder weapon, and rushes off to get an address for Pepperfield.
Frank walks into a house filled with caged raccoons. Just when I think I've typed the weirdest recap sentence ever, I find one to top it. John follows. Frank calls out for Zeke Pepperfield and gets no answer. He sighs and lowers his gun as he sees Pepperfield slumped over a table, brain missing. Suddenly, a guy in a black hoodie bursts out of a nearby room, yelling. Because the best way to sneak out of a house is to yell as loudly as possible so the cops don't miss you. Black Hoodie runs out of the house carrying a bag. Why didn't Frank just shoot him? John runs out the front door and follows. The music in this scene is so from an episode of Starsky & Hutch. Black Hoodie runs down an alley, past a chained, barking dog, and runs into a car. He gets back up and runs off. The dog somehow detains John, even though it's chained up. Black Hoodie runs out into the street, where he is hit by the only car around, but manages to get up and run off again. John comes around the corner and asks the car's driver where Black Hoodie went. The driver doesn't know. John and Frank look around, but Black Hoodie seems to have just disappeared. Man, that was some bad music.
Frank and John walk out of Zeke Pepperfield's house. Aw, R.I.P. Zeke Pepperfield. Frank comments that Group Otto is getting smaller and smaller. They see Wesley arriving on his bike, and Frank says that Wesley is "following [John] around like a lost puppy," and that John needs to get him out of there. John wonders why it's his responsibility. Frank points out that the way that Wesley looks at John, he's responsible for the kid whether he wants him or not. Frank takes off to see his own kids. John sighs and walks over to ask how Wesley knew where to find him. Wesley says that he listened to the police scanner over the web. Wesley compliments John's car and asks what color it is, and says that he can't tell because he's color-blind. This strikes John. Wesley babbles about a kid at school who was bragging about his dad's new Porsche, and asks John if they can drive by the kid's house in John's fancy car. John wants to take a trip to the Seattle Optometry College together to test their color-blindness, and he's all fired up about it. Wesley is still hot on the car idea, but John keeps pushing the color-blind test. Wesley backs down and rides off on his bike.
