Tamara Tunie (Dr. Melinda Warner) is added to the main credits starting with this season, even though she does not appear in this episode.
This episode aired six years to the day after the very first episode of the series.
In a pretty obvious homage to Robert Patrick's T-1000, Stabler uses a fire extinguisher to subdue Patrick's character while fleeing from him in a warehouse. Almost exactly like T-1000 getting doused in Nitrogen in Terminator 2: Judgment Day (1991).
