Wasn't Ned, as the fake Hobgoblin, among the resurrected dead? Not sure if he survived the ending or not, but I recall reading that most of the returned characters escaped at the end. Is Ned out there somewhere?
If so, it would make for a good one-and-done story dealing with him and his new lease on life, where he goes from here (even if it's Limbo, if Ned's alive again I'd think it would at least be addressed somehow).
