History Fanfic / CrossCases

* OriginalFlavour: Somehow, this fic manages to feel like a perfect combination of installments of ''both'' parent works at the same time. The sections written from Harry's POV align perfectly with his narrative voice in canon, and the plot is paced well and twisty enough to feel like an actual ''Dresden'' novel, with even the length, number of chapters, and timescale falling within normal range for the series. And on top of that, the sections from the perspective of any of the ''Supernatural''-side characters hew closely to their canon characterizations and somehow manage to feel like an episode of ''Supernatural'' whose events slot in well with both the ending of Season 10 and the start of Season 11, without ever once feeling out-of-place with the sections mimicking a ''Dresden'' novel. There's only one OC of note- the main antagonist -and even they fit nicely into the canon of ''Dresden'', complete with their history with the protagonist being something that could totally be present in canon. It's quite remarkable to see.

* YouRemindMeOfX: Although it's never verbalized, Harry reminds Sam of Dean during happier times with his constant wisecracks and quiet concern for him, and it's the driving force of their friendship. On the road trip to Pennsylvania, Sam even narrates that he could pretend it was Dean in the seat next to him, and the way Harry stirs up [[spoiler:Lucifer]], between his sense of humor and his shit-eating grin, remind Sam so painfully of Dean he can't look. Even early on, Sam unconsciously slides himself into patterns and interactions with Harry that mirror ones he's made with Dean. Commenters on the fic also noticed parallels between Sam and Harry's vampire half-brother Thomas Raith- both have deep ties to demons with similar inner turmoil over it, are the more reserved and depressive one in their respective duos, and have easy, graceful movements and appearances that make them more approachable.

JustForFun/TheOneWith [[AnotherDimension the alternate reality]].

** After Sam hustles a pool shark out of his money, the pool shark's two buddies show up to back him up, and Harry narrates that if they were wearing goggles and overalls, they could have been the spitting image of [[WesternAnimation/DespicableMe Stuart and Dave]].

* BalefulPolymorph: [[spoiler:Doctor Patterson]] is a budding warlock with an unfortunate tendency to transform his enemies and sometimes allies into frogs or toads once they've seen something they shouldn't have, or simply outlived their usefulness. And that includes [[spoiler:Dean, Charlie, Castiel, and Crowley]].

* BigDamnVillains: [[spoiler:Lucifer]] intervenes when [[spoiler:the Denarians]] have Sam and Harry cornered, [[spoiler:taking over Sam and profoundly disturbing the Denarians - and Harry as a bonus]].

-->'''Sam:''' "So I checked the phone’s call logs. It had two incoming calls, both from the same number. It’s a 610 area code, which is a suburb of Philadelphia called Gladwyne-"
-->'''Harry:''' "How do you know that?"
-->'''Sam:''' (blank stare) "I Googled it. The phone has a data plan."
-->'''Harry:''' "...Oh."

* ActuallyPrettyFunny: This and RefugeInAudacity is pretty much the only reason that Harry survives snarking at [[spoiler: Lucifer]].

* BigDamnVillains: [[spoiler: Lucifer]] intervenes when the Denarians have Sam and Harry cornered, [[spoiler: taking over Sam and profoundly disturbing the Denarians - and Harry as a bonus.]]

* JerkassWoobie:
** [[spoiler: Lucifer]] is a textbook abuser towards Sam, but he has one hell of a FreudianExcuse. While [[FreudianExcuseIsNoExcuse this is never treated as a justification for what he does]], it does induce a fair degree of sympathy.
*** [[spoiler: Patterson]], with Harry lamenting how he could have been helped, directed to a teacher. Of course, as Sam points out, instead of trying to get help, he went into BlackMagic instead and turned to a demon.

* MagicAIsMagicA: Despite the various differences in the rules of magic between the two universes, the angel-banishing sigil works on the Denarians as effectively as it works on the angels of Sam's home universe.

* TakeAwayTheirName: Lucifer admits to Harry at one point that "Lucifer" isn't even his original name; God took away all knowledge of his original name before he was banished to the Cage, and not even Lucifer recalls what he was called at first.

* YouHaveOutlivedYourUsefulness: After Crowley [[spoiler:delivers Amoracchius to Doctor Patterson, having stolen it from Demonreach and nearly gotten locked up by Alfred]], Patterson transforms him into a toad and shoves him into a terrarium... alongside the dozens of other people Patterson's done this to.
