they don't have the best cv history but idc this is an au i can do what i want and like i said, steph's my girl. how old is she going to be? i'm assuming she's around tim's age. if that's the case i'm thinking he was the world's most obnoxious RA at some point before he suckered some unsuspecting soul into being his roommate and moved out of the dorms but they could've interacted that way? dick getting all up into his undergrads' business, innocently looking through their shit during mandatory fire drills ('for alcohol and other prohibited items obvs') and trying/failing to create group bonding activities. but he also would've been a semi-messy but genuinely compassionate older brother figure any of them could've gone to with problems or issues and tried his best to offer advice or make things right in the fairest way possible
