Dean lay back in his motel bed, smiling. He had just seen the latest Batman movie and it was AWESOME. Batman was the best superhero of all time.

For once, he wasn't worrying over Dad and what and who he was doing tonight, he was thinking about Batman and the Joker and his latest plan.

He finally fell asleep as he replayed the epic fight scene between the Joker and Batman for the fourth time...

He was woken in the night by a snuffling sound. Instantly awake, his hand reached for the knife he kept under his pillow. His dad had given it to him, after he had came to him, terrified by the 'monster' in the closet.

He reached for Sammy, next to him with his other hand and found his little brother huddled up under the thin blanket, whimpering.

"Sammy! Sammy! Wake up!" he whispered gently nudging him.

Sammy turned around and wrapped his small arms around Dean. His little wet face pressed against his old T-shirt.

"What's the matter?" he said softly, hugging his brother back.

"I- I don't l-like the J-joker." he whimpered, wiping his snotty nose on Dean.

There was a thunderous banging on the wall, separating them and their father.

"Keep it down!" he roared. Dean could practically smell the beer on his breath.

Dean slowly lay down, still cradling Sammy.

"Its okay, Sammy," he whispered into his brother's soft, shaggy hair. "Because I'm Batman."

Years later, after Stanford, John going missing and Jess dying, Sam was tied to a chair, with two men crowded round him.

Sam was panicking slightly. He didn't show it but he was terrified. Where was dean? He had to be coming, he ahd never let him down.

Suddenly, his brother, in all his glory, was standing at the top of the steps.

"Get away from my brother." he said calmly.

The men spun, but Dean dispatched of them quickly.

Dean smiled and looked up at Sam, instantly banishing his worries.

"I'm Batman." and all those years, all those painful memories came rushing back, passing him by until that one night, with his father shouting drunkenly from the next room and the silver of a moon hardly lightening yet another motel room, and his fears of a white-faced man in purple, smiling with his stitched mouth.

And he knew, right then that his brother would never leave him.

And he would never leave him.
