''[[http://www.fanfiction.net/s/3983128/1/Culture_Shock Culture Shock]]'' by Ruskbyte is an unfinished ''Literature/TheCulture[=/=]Literature/HarryPotter'' crossover fanfic.
Diziet Sma, Special Circumstances agent, and her drone Skaffen-Amtiskaw arrive on Earth in search of the human that somehow managed to access both layers of the Grid, a search that takes them to the doorstep of Number Four Privet Drive.
Fast forward ten years. It is time for Harry to return to Hogwarts, a journey he is not eager to go on...
!This fanfic contains examples of:
* BewareTheHonestOnes: [=McGonagall=]'s bluntness is described as harder for Sma to deflect than Dumbledore's playing of games.
* HeroicBSOD: Harry after the troll is destroyed with effectors, causing LudicrousGibs.
-> '''Sorting Hat:''' This is not some silly little game, Potter;
* OutsideContextVillain: Despite the Culture's desire to dismiss Wizarding Britain as primitives, the wizards do things with magic that even their incredible grasp of science has no explanation for.
-> '''Sorting Hat:''' I have been here for a thousand years and have Sorted every single student to ever attend this school. Every. Single. Student.
-> "Do not presume to laud your own moral superiority over me, Potter," the Hat warned.
