At the beginning, Rossi tells Hotch, "Do me a favor. Get that ear checked." He motions towards Hotch's right ear, which is the same ear that was damaged by the SUV explosion in Lo-Fi (2008) and Mayhem (2008). Hotch had been about to enter the bank with Morgan, JJ, and Emily. Rossi was probably concerned that the shockwave may have reinjured Hotch's ear.
The closing song "As It Seems" was performed by Lily Kershaw, daughter of director Glenn Kershaw. Lily Kershaw also appeared in an acting role in the Season 4 finale "To Hell...and Back" and another of her songs "Ashes Like Snow" would be featured in the Season 8 finale "The Replicator."
