Our Dean - Cain's warden - 'e used 'is deal to stop some of the things that went wrong in 'is future. This one that's 'ere now is the one that didn't 'appen for. 'E's the version of the story with the bad ending.

And no, you know that and I know that. But Dean's been in Hell; 'e knows 'ow they can lie and mess with your 'ead and there's not a shred of trust left in 'im. 'Cause 'e just assumes if this is Hell we'd obviously all say that anyway, wouldn't we?
