They'd spent days, nights, practically weeks looking for a cure. Dean was getting worse. Sure, he wasn't shaking up with the King of Hell at bars and singing bad karaoke anymore, but he still wasn't quite right.

Dean was spiraling. He was locked in his room, reading over the same old books every day just to get a glimpse of something that meant anything related to the Mark.

One day, they did. Well, Sam did...

He had been watching tv, when all of a sudden, there was the answer. Right there in those satellite images screened into his television.

Dean wasn't around when Sam figured it out. He had gone to a convenient store not far from the Bunker. But Sam had a bad feeling. He knew Dean needed the cure, now.

Sam and Castiel drove quickly to the convenient store, bursting through the doors only to find Dean holding a man off the ground, eyes filled with black.

"Dean!" Castiel yelled, getting the man's attention, making him hold the guy in his grip tighter.

"Eat a Snickers!" Sam yelled. Fumbling around in his pocket, he tossed the delicious caramel chocolate peanut candy to Dean.

Dean only used one hand to hold the frightened and trembling man up as he caught the Snickers, opening it and taking a big bite. 

Suddenly, Dean's grip on the man loosened, causing him to fall to him feet and allowing him to flee. Dean blinked a few times as if stunned before the blackness faded out of his eyes, making him blink harder and look around in realization.

"The curse was a Snickers bar?" Dean asked in question, taking another bite.

"You're not you when you're hungry," Sam smirked, turning for a close up and winking.
