It's the middle of the night. Sam is fast asleep in his room next door. Castiel is snoring away, as you'd expect at 2am. But not Dean. He is in bed, sat bolt upright. He has his head resting on his knees. Something is obviously bothering him.

He stares at the wall ahead. He doesn't really show any sign of movement or emotions. He is just sat still. Wide awake.

Castiel moans a little as he repositions himself in his sleep. He rolls onto his side, and stretches his arm out to pull Dean in close, as he so often does when he is asleep. But he stirs, when he realises Dean isn't lying next to him. Castiel lifts his head up, to see the back of Dean's head.

Cas smiles to himself in sympathy, and then sits himself up next to Dean.

Dean moves his head to the side, and lets himself smile a little, seeing Cas join him.

"are you okay?" Castiel sleepily asks.

"just having a bad day," Dean replies. He rubs his hands together, as he gets a little nervous – he knows Castiel is going to want to talk about what happened today.

"you seem to have a lot of them," Cas responds, settling into a similar position to Dean, at his side.

"yeah," Dean half laughs, at the element of truth in Castiel's words.

"you cant blame yourself, Dean," Cas sighs a little. He takes a hold of Dean's arm, and tenderly strokes it a little, as they both stare ahead into the pitch black room. "Sometimes we have to do bad things to get good results."

"except, when that happens," Dean replies with sincerity in his voice, "people often forget all the good you did."

"what people?" Castiel smiles, with a little sadness in his voice. Dean isn't to blame. Why cant he see that? "You know the truth. Sammy knows the truth. Who else is there that matters?"

"you, obviously" Dean turns to look at Cas. "You weren't there, you don't know the truth."

"Dean," Castiel brushes away the single tear that has just fallen down Dean's cheek. "I know you never meant to hurt that little girl. You'd never mean to hurt anyone."

Dean just shakes his head, holding his face and trying not to cry. Hearing his husband say out loud what he had done killed him inside.

"you're unbelievable," Castiel declares, shaking his head a little, too, as he recognises Dean's silence.

Dean looks up, facing ahead again, but taking a hold of Castiel's hand. "What's more unbelievable, is that you think I'm a good person."

"you are a good person, Dean," Castiel confirms.

Dean doesn't respond. He doesn't think so. So much bad has happened in his life. So much bad happens to anyone that's close to him. But somehow Castiel still loves him. How?

"come and get some sleep, Dean," Cas pleads with him.

Dean taps Castiel's hand, and forces a half smile out, just for Cas.

"in a minute."

"okay," Castiel nods. He kisses Dean lightly on the cheek, as Dean leans in a little, feeling Cas against him. Just feeling him there is comfort enough. He doesn't have to say a word.

Cas lies back down, still looking at Dean. He is sure to lie on his back, with his hands behind his head, so he can keep an eye on his husband, waiting for him to settle back into bed.

Dean looks up at the ceiling, using gravity to try and force his tears back in his body. He sniffs and wipes away the couple of tears that escaped. He exhales a little, and carefully falls backwards onto the bed.

Dean snuggles himself into Castiel's body, placing his head and palm onto his chest. Castiel wraps an arm around him, and kisses Dean on the head.

"I love you, Dean," Cas comforts him.

"I love you more, Cas," Dean replies, as he cuddles into Cas that little bit more.
