'Yeah, I figured that much. I mean, what are you?' Dean's voice is angry.

The angel turns to him, looking Dean in the eyes and hoping he is believed. 'I'm an angel of the lord.'

They stare at each other, unspeaking, until Dean stands up and tells Castiel to 'Get the hell out of here. There's no such thing.'

'This is your problem, Dean,' Castiel says, knowing he speaks the truth that he learned from the man's soul. 'You have no faith.'

Castiel wonders how he can make the man before him believe the truth, and then it hits him; his wings. He calls a flash of lightning, spreading his wings so that their shadows manifest on the walls with each strike of lightning. He's averse to letting people see his wings, but with Dean it feels natural.

'Some angel you are,' Dean says, and it hurts Castiel, deep inside, but he doesn't quite understand why. 'You burnt out that poor woman's eyes.'

Castiel looks down; he regrets what he did, but he was doing it for Dean, really he was. 'I warned her not to spy on my true form. It can be overwhelming to humans. So can my real voice, but you already knew that.'

'You mean the gas station and the motel,' the Winchester asks. 'That was you talking?'

The angel nods.

'Buddy, next time lower the volume.'

'It was my mistake,' Castiel replies. 'Certain people, special people, can perceive my true visage. I thought you would be one of them.' He's telling the truth, because the truth is important, especially for this man, the one he dragged from the depths of Hell. 'I was wrong.'

'And what visage are you in now, huh?' Dean asks, voice harsh. 'What, holy tax accountant?'

'This, this is…' Castiel pauses minutely, wondering how to explain. 'A vessel.'

'You're possessing some poor bastard?'

'He's a devout man, he actually prayed for this.' Castiel is trying to help Dean understand, but the man is so caught up in his own beliefs he fails to accept the metaphorical hand being extended to help him through this.

'Look pal, I'm not buying what you're selling. So who are you really?'

Castiel squints and tilts his head to the right, confused. 'I told you.'

'Right. And why would an angel rescue me from Hell?'

Castiel steps forwards. 'Good things do happen, Dean.'

'Not in my experience.'

'What's the matter?' Castiel asks, because he wants so badly to understand this man, his mission, he wants to know everything, to be able to share everything with the person in front of him despite them only having met. 'You don't think you deserve to be saved.' The angel has seen the Winchester's soul, knows that that's what Dean is questioning most; his own validity of being something worth saving.

Dean's lip quirks, face dark, and he's about to say something, Cas can see it in his eyes, but changes at the last second. 'Why'd you do it?'

'Because God commanded it.' Dean's jaw tightens, but Castiel continues. 'Because we have work for you.'

'What kind of work?' Dean asks, looking thoroughly confused.

'All in due time,' Castiel says, before flying back to Heaven. He wanted to stay, but they were not his orders. He was to save the Winchester, inform his of his duty and then return.

Nowhere ever in the rules did it say Cas was to fall in love with Dean. It wasn't part of anyone's plan, no one anticipated it. But he did anyway. And they both suffered the consequences.

A/N: Wow, it's finally done... I've been working on this fic for about 2 years and five months, and I have to say, I didn't expect it to take this long...

Thank you to everyone who's stayed with me through my sporadic updates and left comments and reviews, and favourited it. You have no idea how much it means to me.

(Sorry if I killed your hearts... I have to say this was the original ending all along..)
