Headcanon: Stiles becomes a history teacher, Scott a veterinarian--like Deaton. They own an apartment in the complex adjacent to Derek's place. The pack always troops over to steal Scott's cookies that he made specifically for Stiles, since teaching is a 24-7 job. Scott doesn't dare use his alpha powers when the cookies run out, because Stiles tells him that the thought is enough--and there are a few things better than cookies anyways. ;)
In my head Stiles always ends up being a teacher, I’m not really sure why though because honestly Stiles doesn’t seem the type to have the focus to be a teacher like, he’d go off on some tangent about something that he’s really excited about and his students would be like…Yo Mr. Stilinski this is History why are you talking about circumcision and they would constantly invite Derek over for dinner because tall dark and broody obviously can’t take care of himself and he rolls his eyes and comes every once and a while if they promise to keep the PDA to a minimum. They never do.
