Part 1
—As noted in Time Flies, in the "Phillipverse" of my stories, Time Turner suffers from mild OCD.
—In poker, a straight flush is a hand that contains five cards, all of the same suit, in sequence (e.g. the 9, 10, Jack, Queen and King of Spades). It is the highest-ranking poker hand.

Part 2
—"Great whickering stallions!": reference to the episode Slice of Life.
—Time Turner finds the sound of a clock ticking soothing: it calms him down.
—Dinky loves her parents, but she is far, far too familiar with their relationship with disaster.
—"I just don't know what went wrong!": reference to The Last Roundup. This is going to be a frequent phrase heard around Derpy.
—Also in the Phillipverse, Dinky has inherited some of her father's OCD, which manifests as mild germaphobia.

Part 3
—Drury Lane: reference to the nursery rhyme "Do you know the muffin man?" which is a reference to Derpy's love of muffins.
—Ditzy's fighting style is similar to drunken boxing, which I thought would be a good fit for her.

Part 4
—Canter Nostra: play on Cosa Nostra, Italian for "our thing," the proper name for the Italian Mafia.
—"Allons-y!": French for "Let's go!" Reference to Slice of Life, which is itself a reference to Turner frequently being compared to the Tenth Doctor from Doctor Who.

Part 5
—The chapter title, "The Clock Tower," is also the title of a 1995 survival horror point-and-click video game.
—"Neither rain nor snow nor sleet nor vicious criminals!": play on the US Postal Service unofficial creed, "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds."
