A/N: I had a plot bunny and this happened. Please read and review. Feedback helps me become a better writer. Also, I'm English so there may be weird spellings. All mistakes are my own as I have no beta.

Sam: 4

Dean:8

Dean lay on the motel bed, which had a curious yellow stain on the sheet, listening to Metallica on his Walkman. He resisted the urge to sigh as he felt a distinctively sticky hand tug his sleeve. "Yeah Sammy?"

"Deeeeean. Me bored." His annoying kid brother whinged.

"And?" As if it could be that easy.

"Play with me!"

With an internal groan, Dean rolled onto is front and gave his brother his full attention. "What do you want to do?" He really really hoped it wasn't pirates again. His nose still hurt from the last time.

Sammy frowned in thought. This probably felt like a life changing decision to a 4 year old. "Me want to play…" he paused dramatically. Just get on with it! Dean thought desperately. "Dress up!" Sammy announced.

Well, that wasn't too bad. "Fine, what are we dressing up as?"

Sammy frowned again. "Um. You choose." He stated with an enormous smile.

Dean scrambled for ideas and picked the first one that appeared. "Ok. We're dressing up as our favourite superheroes."

Sammy frowned again. "But Dean! Don't know who to dress up as."

Dean sighed. His little brother could be so infuriating sometimes. "Well I don't know who your favourite superhero is!"

Sammy pouted and used his puppy eyes. Dean felt his will power disintegrate into nothing. "Who's the most bad ass person you can think of?" Sammy thought a bit longer then an infectious grin spread across his face. Dean felt himself smile in response. If Sammy was happy it meant he was doing good and it didn't matter dad had been gone almost a week or that they'd had Mac 'n' Cheese three days in a row.

"Ok" Sammy was practically vibrating in excitement. Dean cast his eyes over the deteriorating room. His gaze fell on a ancient blanket which was a nondescript colour that could be interpreted as almost red. Fine, he could be superman. Dean tied the blanket best he could around his neck and pulled a clean pair of boxers of his jeans. It would have to do.

"Sammy? You ready?" He called without turning around. "1…2…3…" he spun around to the sight of Sammy in one of Dean's shirts. "Who am I?"

Sammy squealed as he worked out the answer. "Dean's superman! Who is Sammy?" He asked.

Dean frowned. Who could it be? It was batman, superman, the hulk or captain America. He sighed then gave up. "I don't know, Sammy."

Sammy smiled and gave Dean a hug. "I'm you because your the best superhero ever."
