- This was the last episode to air in 2011.
- Early in the story, Beckett accuses a decorated war veteran of being evil and denies that snipers had any capacity to do good. The story ends when Esposito, himself a marksman, saves Beckett using these very techniques.
- Beckett's final confession to her therapist essentially acknowledges Castle's critique of her in Knockout. Namely, that she let herself be defined by her mother's murder, was hiding from having real relationships because of it, and was afraid to find out who she'd be if she ever caught her mother's murderer.
- This episode also further shows the extent of Beckett's PTSD, which Castle first notices in the opening episode of this season when a suspect points a gun at Beckett.
