- Castle says, "Well there was that last episode of The Sopranos," in reference to all the cameras shutting off right before the victim, Jack Sinclair, dies. This is when Tony Soprano, on the TV show The Sopranos, has the camera suddenly shut off on his last moments as the series ended, possibly implying his death.
- Watch For: Kate's reaction when Pete Benton talks about what he was doing the night Melanie was killed. It's subtle, but it's there.
- Lanie and Esposito officially end their relationship until Till Death Do Us Part in this episode after Jenny's innocent question about marriage causes a point-of-no-return fight between them.
- Fredric Lehne, who played Detective Addison Smith, was known for playing the Yellow-Eyed Demon and Prince of Hell, Azazel on Supernatural. At the end of the episode, Beckett tells Castle that Smith claimed to be possessed by a demon.
