"Sam..." He wasn't wrong. It was his choice, he made it, and he probably should have known better. Still, she didn't want him to keep beating himself up over it. It was a mistake, and he was allowed to make them. "You're not the first person to trust someone you shouldn't have, and you won't be the last. And it's not different because it was a demon." She paused for a breath, to keep herself calm more than anything else. "You're not different, not as different as you think you are. That darkness inside of you? It's got nothing to do with demon blood, I don't care what anyone says! Everyone has a dark side, no matter who they are or where they come from. You're so aware of yours because you think something put it there...but it's normal. It would still be there without all this."

She felt like she'd given this speech a million times, only about meteor radiation instead of demon blood. They were all afraid of turning into criminals and murderers, and she always did her best to explain to them they really weren't as different as they thought they were. It was different this time, though. This was Sam Winchester, the man she loved, who she could see herself with for the rest of her life, and if it took her that long, she would convince him he wasn't the monster he thought he was.
