I have this haunted hotel au where Esther finds a ancient ritual in her spellbook that promises to bring Abaddon his demon form but on earth and Abaddon is ecstatic to go through with it, why wouldn't he? It's his true form. And he doesn't need to deal with those assholes in hell.
Well the ritual goes terribly wrong for whatever reason and Esther freaked out thinking she might've hurt Abaddon but then it's revealed the original boy is in control of his vessel once again after centuries and Abaddon has been transformed into a human body of his own.
