A mystery figure on a motorcycle chases down a young skateboarder in the dark streets. BANG! BANG! The motorcyclist shoots the skateboarder. The victim is 21-year-old Logan Moore. He was a pro skateboarder who was in town for the New York Streets Sports Festival. Castle and Beckett discover that another pro, Manny Castro, had a beef with Logan. He was caught on tape threatening the victim after he caught him ransacking the festival office. Logan was looking for something that he swore was a matter of life and death. It looks as though he was right.
Tommy Fulton, the festival CEO, says the only thing missing from his office after a break-in is his gun. He also says that Logan had received a call from someone in his past that upset him. The victim also received calls from a club run by the Albanian mob. Logan had been staying at the loft of a trust fund kid named Ross De Koning. The two of them used to skate together. Ross says Logan's mom dated an Albanian named Enver Kotta. The kid helped send this bad man to prison. Enver swore he'd get even one day.
Enver admits he met with Logan only to make amends. He gave him $3,000 so Logan could take care of something before it was too late. Logan was seen carrying a heavy black duffle bag before he was killed. He put it in his gym locker. The bag contains rock climbing gear, a gun and tools for picking locks. Logan also bought an old high-8 camcorder. Video footage shows a motocross rider named Carter Wexland as the one who entered Logan's gym. The guy has a record and a motorcycle just like the one used by the killer.
Carter says Logan hired him to help break into an office. This was all about making things right for a friend who had died. The building Logan broke into belongs to a lawyer named Brett Zaretsky, who says a thief never broke in to his place even though all indications seem to indicate that's not the case. The attorney is covering up something.
Castle and Beckett meet with Logan's incarcerated mother. She says a scrawny boy from the neighborhood named Jay Dixon was killed in an accident six years ago. Logan may have been seeking justice for this young kid's murder. He bought the camcorder to view footage that was shot the day Jay was killed. The team finds a piece of the tape. It shows Tommy Fulton threatening to kill Logan if he ever told anyone what happened to Jay. Brett Zaretsky represents the guy. Tommy Fulton fires him. He wants to tell Becket and Castle exactly what happened.
Tommy reveals that he was making skateboarding videos with Logan, Jay and his friend, DK, six years ago. Things got out of hand during the shoot. DK snapped and killed Jay. He made a deal to give Tommy $5 million to keep quiet. It was in a trust fund he'd be able to access on his 21st birthday. The DK in question is Ross De Koning. Case closed.
Castle stayed up all night trying to beat Beckett at a game of Scrabble. He hates to lose. He challenges Beckett to another game where she spells out the word "quixotic" for the win. In other news, Lanie is going to be Beckett's Maid of Honor. Both Esposito and Ryan believe they would best man to be, well, Castle's best man. They start sucking up to the groom-to-be before deciding to be co-best men. Too bad Castle already asked Alexis to stand by his side. As for the Scrabble rematch, that's not happening. Castle and Beckett opt to play strip poker instead. Everybody wins!
