21 Days of Disney!

Thanks anon! My headcanon: Stef has this totally functional selfishness. He is used to situations where you either exploit people or get exploited yourself and is angling for the former...until he meets Van. He's very afraid to give too much of himself; even Medren knows little about his past. But Van completely upends all his survival rules, and without even meaning to, he leads Stef beyond all his fears. (And then dies, leaving Stef with a bunch of new fears, not least ever getting close to anyone ever again. Isn't it great. :D )
