When Walker (Jared Padalecki) is talking to Captain James about having been put into the trunk of a car earlier in the episode, Captain James makes a comment comparing Walker to "a moose," which is a reference to his overall tall stature. Jared Padalecki also played Sam Winchester, a hunter in Supernatural, who was referred to as "moose" by Crowley, who was a crossroads demon and later the King of Hell.
