Castle and Beckett investigate the murder of a web celebrity.
Tropes that appear in this episode:
- Bait-and-Switch: When the team realizes that the posters of the "Spoiled Bratz" memes are in danger, they are seen trying to warn one of them, as she ignores their warnings. At first this seems to be setting her up to get killed but actually she (and the detectives) end up discovering the dead body of her co-star moments later.
- Book Ends: Adam Lane intends to finish his revenge spree on the same place that his life was ruined by bullying.
- Failure Montage: Instead of the planned webmercial, Castle's publishers use all the outtakes and turn it into an autotuned joke.
- Law of Conservation of Detail: When both website owners Owen and Kent Wilder and their IT guy all appear and provide information to the detectives in the same scene, a savvy viewer might suspect that one of them has to be the culprit. This is zig-zagged though as none of them are the killer, but all three prove important when Oren and Kent end up kidnapped by the culprit and their IT guy helps the detectives try to trace their location in time to save them.
- Never My Fault: Adam refuses to accept the idea that he's the villain, constantly stating that he's just the "victim" taking revenge on a system that failed him.
- "The Reason You Suck" Speech: Beckett breaks the culprit down that he was a loser back when he was the victim and still is now, making it clear to him that everyone who bullied him was right and they just sensed the monster he would become.
- Saying Too Much: Beckett provokes Adam into saying just enough that the detective who investigated his original case remembers how Adam described his initial bullying experience, allowing them to trace his final victims to his old school changing room.
- Too Dumb to Live: When one of the Spoiled Bratz learns she's being targeted by a serial killer her response is to go full brat and insist she's going to a widely publicized party.
