Sam was trapped and the water was slowly climbing. Why do I have to play hero all the time? He could see there was no way out of the car as it was slowly sinking into the river. The air pocket was the only thing keeping him alive. He was going to drown for nothing. The owner of the car took an overdose at the wheel; he'd already died when the car hit the water. If only Sam had known.

"Sammy!" Dean called out over the bridge.

Sam's car had been deserted there. The driver's door still open from where he had rushed out. His cell left abandoned on the passenger seat – Dean had tracked him all the way here but as soon as he'd arrived, Sam was nowhere to be seen.

"Dammit, Sammy. Where the hell are you?"

Dean spun around, squinting his eyes all around him. There was nothing around but empty road, a river and a field full of what looked like sheep. He knew they shouldn't have split up. He knew something was up when Sam stopped answering his phone.

"Sam!" Dean repeated, shouting so hard that it was beginning to strain his voice.

He was starting to panic now… until the skid marks on the bridge caught his attention. Tire tracks. A car had driven off the bridge at full speed. And the marks were fresh.

Dean's heart dropped into his stomach as he looked out over the now calm river.

"Sam" he whispered.

Then he jumped.
