The Winchester brothers barely got a glimpse of the rotted corpse before it was taken to the morgue. Harlie Peterson, age 15, looked like she was in her late thousands. Most of her skin had rotted away, but what was left was more wrinkled than your grandma.

"So, what could have done this?" Dean asked.

"I don't know," Sam shrugged, "maybe a witch like the one you lost 50 years to in a poker game."

"I don't think she was playing poker, and I doubt she could gamble away more than 15 years, anyway. Isn't that against the rules?"

"Well, I don't know what else this could be."

"Then how about we head back to the bunker, and you can do your whole nerdy, research thing.

They headed back to the Impala and drove off. Dean turned the radio up obnoxiously loud when Carry on my Wayward Son came on. Dean sang along as usual. He pretended not to hear when Sam asked him to turn the volume down, and turned it up instead. However, he turned the radio off completely when he heard the first lines of Asia's Heat of the Moment, knowing how his brother felt about the song.

At last, they arrived at the bunker to find Cas waiting for them with a pie he had bought for Dean. The older brother's green eyes grew big as he saw the cherry dessert on the table.

"Should I leave you two alone?" Sam laughed.

"Yes. Just me and my pie," Dean mumbled through a mouth full of pie.

Sam blinked. That wasn't what he meant. He rolled his eyes at his brother and began researching creatures or spells that could cause such rapid and extreme aging. At long last, he came across a Greek mythology book.

"Hey, Dean. Come look at this. The Greek god of time, Cronus. He has the ability to slow down, speed up, and reverse the aging process. It could be him," Sam explained, closing the book.

"Okay, let's summon this son of a bitch and put an end to this... right after I finish my pie," Dean replied, grinning.

They set all the traps they needed and retrieved an arrow from Artemis, just like the one they used to kill Zeus a few years ago. They performed the summoning ritual, making sure to do everything right.

A small, bearded man appeared a few minutes later. He had a confident smile on his face.

"Ah, the Winchesters," he said in a gruff voice, "thought you'd be taller."

"Well we could say the same thing about you," Dean replied, looking down at the four-foot tall god in front of him.

"I assume you summoned me because of those poor dead people. Yes, I confess, I killed them. You may ask 'why? Why would he do such an awful thing?' The answer is simple. Because I wanted to!" He began giggling uncontrollably.

"Can I stab him now?" Castiel asked.

"Go ahead. We have all the information we need," Sam answered.

Cas began to walk towards the man, who was still grinning. He wasn't begging for his life. In fact, he looked as if he was even happier than before. Something was terribly wrong.

"Wait, no! Don't do it, Cas!" Dean yelled, running to try and stop his friend. But it was too late. Castiel had already driven the arrow into Cronus' chest. The god died with a grin on his face, but had one last trick up his sleeve. In his haste, Dean had accidentally broken the line of the trap, allowing Cronus to use magic.

A pale blue light surrounded Dean and Cas. They both looked around, confused, when suddenly, they began shrinking. Not only that, but they got younger. This continued until both men looked to be about five years old.

"Looks like I'm the older brother now," Sam chuckled.
