* BaseBreaker: the Ray Wars.
* CreatorsPet: Ray Kowalski, who is praised by Welsh and Fraser for his wonderful service record in the Chicago PD, and is told by Fraser that he would be "proud to be his friend" not long after he and Fraser met. The actor was even ''hand-picked '' by Paul Gross to be Kowalski because he was Paul Gross's friend in Canada! And during Season 3, Ray Vecchio, by contrast, was believed to be corrupt and a murderer, probably to make Kowalski look even better.
** In fan fiction, Kowalski is frequently a MartyStu. Fanfiction writers tend to make Fraser and Ray Vecchio not perfect and dwell on their faults.
* FridgeLogic: Fraser doesn't carry bullets in his gun because he doesn't have a gun permit. [[YouFailLawForever Wouldn't that mean he can't carry a]] ''[[YouFailLawForever gun]]'' [[YouFailLawForever at all in Chicago?]]
** That is correct: an unloaded gun would still be seen as illegal under Chicago law. However, as a RCMP Officer, he would be permitted to carry a loaded firearm in the States. Fraser should have been well aware of this considering his familiarity with all the laws.
* HilariousInHindsight Paul Gross, who in this movie played the UpToEleven ideal version of a Royal Canadian Mounted Policeman, would later star in a MadeForTV movie called ''Murder Most Likely'', BasedOnATrueStory about a [[DirtyCop crooked Mountie]] who may or may not have murdered his wife.
* HoYay, which led to m/m fanfic with Fraser and both Rays.
* MagnificentBastard: you just have to stand in awe to [[spoiler: Victoria's]] plan: committing theft and murder while managing to leave no trace and frame Fraser and Ray for the whole thing
* RetroactiveRecognition: Also HilariousInHindsight: Fraser's partner is replaced by a [[Series/BattleStarGalacticaReimagined cylon]], and [[OnlySaneMan he's the only one to notice]].
** [[{{CSI NY}} NYPD Detective Stella Bonasera]] is a bank robber! (Or Dr.Hansen from 'Providence').
* YaoiFangirl: Almost all of the fanfiction written today is Fraser/Kowalski, or has Fraser/Kowalski in the background. Fraser/Vecchio, and het and pure gen stories used to be more popular.
** And F/K fanfic is often GayAesop, with Ray Vecchio and others being the disapproving homophobe(s) who need to learn a lesson
