- Eddie (the Piano Man), upon seeing Castle, plays a few bars of a song. Castle smiles, tips him, and thanks him for remembering. The song is the same "action theme" that often plays when Castle gets physical with a criminal. It's first heard in Home Is Where the Heart Stops, when Castle sings it to himself while sitting in Beckett's car, and then later as they drive away after apprehending the criminal.
- This episode has Beckett, Castle, Ryan, Esposito, Captain Montgomery singing Billy Joel's song "Piano Man" near the end of the episode.
- Beckett reveals she had braces as a kid.
- First appearance of The Old Haunt, that apparently become a regular hangout for the team.
