Remix: It Started With An HP Box Set (The Footnote-Happy Remix) [Crowley/Aziraphale, 100 Words, Rated PG] by benebu
Crowley lent Aziraphale his Harry Potter books so that the angel wouldn’t be under his feet while he was working on a project of his. 
 He sincerely thought the angel would enjoy reading them, if only for the heavy homosexual subtext of Quidditch. 
 He hadn’t counted on Aziraphale becoming so invested in the characters that he’d show up a few days later, all worked up about Sirius’ death. 
 Crowley then did the only sensible thing and introduced him to online fanfiction. 
 Ensuing internet downtimes in Soho may or may not be caused by a demon missing his favourite angel’s company.
