There's a new pony in Ponyville. His past is a mystery, and he doesn't get well with others, that much they know. The other thing they know is the two year old he takes care of by himself, and that he's not a full pony. The last thing they thought he needed was a relationship. But that's the exact thing he's going for, and the pony he's going for might be enough to push him past The Limits Of Sanity.
