One particularly hot summer day, Sam takes Dean to the park.

Prompt: Purgatory is for monsters. There's nothing set in place for a human and Dean is starving. What edible flora he can find is few, far between. When Sam punches through the world to get to him, Dean - though whip fast and dangerous from being hyper-alert - is rail thin, jutting hip bones, green eyes huge in his face. Sam slowly reintroduces Dean, not just to food and the comfort of a constant meal, but to warmth again, human interaction again, safety and caring again.

After eventually finding a ritual that worked, Sam has sprung Dean from Purgatory, but there are a couple of problems: one, Dean's re-appeared in an alleyway in London and two, he's so broken physically and mentally that he's been classed as a 'vulnerable adult' and has been placed under the guardianship of Social Services. When Sam arrives at the hospital he quickly realises that broken bones are the least of his worries...

Prompt: Dean's back from Purgatory, and things are finally settling down. Sam's not crazy, the Leviathans are gone, and life is actually...sorta peaceful.

Except for one thing. See, Purgatory's full of monsters - a few ghosts, yeah, but no humans. It's been months (years?) since Dean's seen a human being, let alone talked to one or touched one. Every time he has to interact with anyone besides Sam, it feels like his soul's being dragged out of his chest Alien-style until he's legit weak and shaky and feverish just from the human contact. But talking to people is part of the job, and he's Dean friggin' Winchester, so he deals with it. Basically, I could use some maladjusted Dean freaking out about ALL THE GODDAMN PEOPLE, and some understanding, caring!Sam, not pushing him for explanations, but just *being* there."
