You're absolutely right, Demo belongs in a diaper and should be padded up 24/7. Lord knows that rec room couch screams for mercy every time he plops down after work and starts drinking, knowing it's gonna get heavily soaked. Willing to bet he's got whiskey dick and constantly pisses himself during sex. And this being the case too when Medic's wife cheated on him with Demo. Needs literal magic to get it up but no magic in the world can take away his urinary incontinence. At least he doesn't shit himself (regularly, that is).
