'Dean, tell me you remember how you ended up in the Dungeon.'

The three of them were now in the library of the bunker, with Castiel looking down on Sam and Dean with a concerned look on his face.

Dean searched his mind for any memory of the past few hours, but he found nothing – in fact, it felt like it wasn't just tonight that was empty... It was like a whole time period – a person – was just erased from his brain, all just a black hole now... And all that he could see in the hole were two red eyes. He looked at Cas and shrugged.

'I got nothing.' Cas turned to Sam.

'Can you?'

Sam shook his head as well.

'No, sorry.' Cas sighed and shook his head.

'This is bad. Very, very bad.'

'Why?' Dean stood up to become eye level with the angel. 'What's wrong? And who's Crowley?' Cas looked at him and took a breath.

'Crowley... is a Demon.' Dean slowly sat back down. 'More specifically, the King of Hell. And he was... Helping helping us with something. You recruited him yourselves.' Sam and Dean spoke up at the same time.

'Here?'

'No way.'

'Not in a million damn years would that happen.'

'King of Hell? Not a friend.'

'OKAY!' Cas overpowered the two intensely. He looked at them with force. 'He was of our acquaintance for a period of time, but of course no longer.'

'Why don't we remember this son of a bitch, then?' Dean asked, not missing a beat.

'From what I gather, Crowley used an old latin spell that makes you forget the past twenty-four hours...'

'Okay,' said Sam slowly, 'but that doesn't explain why we can't remember him.'

'He must have used another kind of spell or magic...' Cas pondered, 'he maybe mixed a spell to create an absence of himself in your minds, but...' He trailed off.

'But what?'

'But even with that, he couldn't erase himself completely.'

Suddenly the red eyes in the back of Dean's mind glowed prominently, and he and Sam simultaneously snapped up and yelled.

'Red eyes!'
