Madness visits Division Three.
Tropes:
- Alternate Timeline: The whole episode explores other ways David's (and Amy's) life might have gone.
- The Bad Guy Wins: Billionaire David sees Amahl Farouk in the mirror, implying that the former is under the latter's control, or at least corrupted by his influence.
- Breather Episode: Nothing actually happens in terms of the Season 2 storyline.
- Crazy Homeless People: The crazed elderly version of David that lives on the streets.
- Composite Character: Evil billionaire David boasting he can read the mind of every human on Earth sounds reminiscent of the Gamesmaster, a minor X-Men villain which was psychically linked to every mind on the planet.
- Dark Messiah: Evil billionaire David sees himself as god's chosen vessel.
- Depraved Bisexual: Evil billionaire David keeps a younger woman and a younger man in his mansion.
- Dragon Ascendant: One version of David becomes one to businesswoman Laura Mercer, not only taking over her position, but making her subservient to him and becoming the richest man in the world.
- Downer Ending: Almost all of them. Billionaire David arguably does the best, but he becomes the Shadow King.
- Driven to Suicide: One version of David dies after hanging himself. Amy brings a bouquet of flowers to his tombstone, and the epitaph reads, "Taken Too Soon."
- Evil Brit: Billionaire David speaks with a hint of a British accent.
- Evil Is Petty: Billionaire David keeps his old boss as his personal assistant because he knows she resents him.
- Evil Sounds Deep: : Billionaire David speaks with a deeper voice.
- Feeling Their Age: David ends up infirm and near catatonic in one timeline's future.
- I Just Want to Be Normal: In one version of events, David settles down and has kids.
- Katanas Are Just Better: The version of Kerry in crazy homeless old David's timeline is working with Division 3, and she uses one to kill David.
- Mythology Gag:
- The version of David that spends his entire life on meds and under the care of Amy ends up bald and in a wheelchair, reminiscent of the elderly Charles Xavier in Logan.
- The evil billionaire David has a hairdo similar to the elderly Magneto in the X-Men Film Series. Moreover, he speaks with an accent similar to Patrick Stewart's portrayal of Professor X.
- Psychic Nosebleed: David (or the Shadow King, or David corrupted by the influence of the Shadow King) psychically attacks his sister out of mild annoyance in one alternate future.
- Soul-Crushing Desk Job: The version of David working at the IRS.
- Shout-Out: The scene in which crazy homeless David is attacked by delinquents is a shot-by-shot recreation of a quite similar scene in A Clockwork Orange, one of the inspirations for the aesthetics and references in the show. The captions even refer to them as "droogs."
- Take Over the World: Evil billionaire David seeks to unite mankind under his rule.
