Episode Title: Unusual Suspects
A play on the phrase "The Usual Suspects", which is also the title of a movie containing unreliable narratives: 1995's The Usual Suspects. The episode referenced the movie a few times, with a questionable character making up a story from objects he/she sees around the room, jail scenes, and the hard-to-explain opening that is revisited later when it is much more easily understood.
The title of the 1995 film is taken from the 1942 classic film Casablanca. Captain Renault's (Claude Rains') final line is "Major Strasser has been shot. Round up the usual suspects". The Marx Brothers 1946 comedy A Night in Casablanca appears to start with that rounding up.
