Sky High Headcanon:
Warren and Will become roommates.
Because Warren works in the food industry, he keeps his kitchen meticulously clean. He washes dishes after they are used, wipes down the outside of the oven, sanitizes the counter and sink.
Because Will grew up in an affluent suburb, had parents who worked odd hours and probably a housekeeper because of it, Will is more laid back and casual with his kitchen habits. He’ll put dishes in the sink to soak, but won’t wash them immediately. He never wipes down the appliances. And he doesn’t even know how to sanitize a counter or sink.
Needless to say, the kitchen is something that Will and Warren argue over a lot.
