In The Woods Somewhere (слэш)

Peter travels with various carnivals, showcasing a massive black wolf he parades as a man-eating beast. In his caravan he keeps Stiles, his most precious possession who is much more special than he may outwardly appear. Stiles feels a kinship with the creature through their mutual captivity, so when he makes his escape he frees the wolf as well. Like Stiles though, the wolf is also more than he appears.
