perfect aubrey went through a string of misguided flings after breaking up with her longterm girlfriend, so i'm thinking her and quinn could've met on tinder, had a well enough time, the next day they both just ghosted on one another and then aubrey shows up at cvs a few weeks later and makes some terrible "cleanup on aisle awkward" joke and now they're friends. and quinn can threaten her in various colorful ways when she tries to put a bag of m&ms on layaway
