Continuity mistake: Just before Gus is awoken by noises in his apartment, there is a shot of his alarm clock. The time shows 6:07PM.

Chosen answer: "Psych: The Musical" was supposed to air during the regular season 7 schedule, before Chief Vick is suspended and Jules discovers Shawn's lie, but the network decided to push it back to air as a special episode, sort of as a tie in with the holiday season and a lead in to season 8, which was to begin only a couple of months later.
