*****************************************************************************

Sam Winchester woke up with a pounding headache and a queasy stomach. Why had he let Dean talk him into drinking last night? He opened his eyes slowly, wincing as the sunlight streaming in from the window hit them. The first thing that he noticed was a girl’s arm wrapped around his chest. He turned slightly, trying not to disturb her as he took a look. She was young (Oh, god, was she even *legal*?) with long brown hair, and she was snuggled up against Sam, her arm wrapped tightly around him.

Sam didn’t remember bringing her back to the hotel with him. Hell, he didn’t even remember her *name*. He didn’t do things like this; Dean did things like this, but not Sam. He glanced over to the other double bed, but it hadn’t been slept in, although Sam was sure this was their room; he could see his bag on the floor. He was going to kill Dean. He knew Dean had to be behind this somehow; he was always trying to get Sam to hook up with women, but Sam had never been a one-night stand kind of guy. And even if he had been, it was still too soon after Jess.

Slowly and gently, he pried the girl’s arm off him and slid out of bed. He quickly got dressed, and was still contemplating whether or not to wake her up when the point became moot.

She opened her eyes, wincing against the sunlight. She blinked a few times, and then looked at Sam and screamed.

That could not possibly be a good sign.

“Who are you?” she said, looking directly at Sam. Oh, boy. Apparently she didn’t remember last night, either. Sam hoped he wasn’t going to wind up getting arrested over this.

“Sam Winchester. And you are?”

“Dawn Summers.” She looked under the sheet she was wrapped in and then quickly pulled it up over herself again. “Did we….”

She trailed off, but Sam knew what she was asking. “I think so.”

“You don’t remember either?” Dawn asked.

Sam shook his head, then regretted it as another wave of pain went through it.

“Where are my clothes?” Dawn asked.

Sam located them, then gathered them up and handed them to her.

“Could you give me some privacy, please?” she asked.

He blushed, realizing that he was staring at her. “I’ll be in the bathroom,” he said.

He gave her what he figured was enough time, then came back out. She was just finishing buttoning her blouse. For a moment they just stared at each other.

Then Dawn said, “I better go. My sister will be looking for me.”

“And I should be looking for my brother, since he obviously didn’t sleep here last night,” Sam agreed. He was glad that Dawn seemed calmer now. Maybe this was a salvageable situation, after all. “I could call you later?”

She frowned. “I don’t think that’s such a good idea. Listen, can’t we just forget this ever happened?”

“Uh, okay,” Sam said. “If that’s what you want.”

Dawn nodded, and then all but ran out of the room.

Sam started tidying up, and that’s when he found it. A piece of paper, innocuous enough looking, lying face down on the floor. He picked it up, turned it over, and read it.

It was a marriage certificate. His. And hers. Sam read it three times, not believing what he was seeing. Then he raced out of the room, trying to catch her, but she was already long gone.
