Color.

Young Sasuke crawled onto his sleeping brother's bed, he tried to use stealth, but failed.

Itachi jerked awake and held a kunai to his baby brother's throat. He sighed. "Sasuke, what do you want at this late hour?" Sasuke stared at the kunai. "Um, what color is the moon?"

Itachi blinked and stared at his Otouto.

"Sometimes I think it's red, blood ride." Itachi sighed.

"Blood red?" Sasuke looked up at the moon.

He stared for a moment.

"I don't see it, Nii-san."

"Oh? Well..." Itachi smiled and picked Sasuke up and set him on his lap. "How about now?"

The Otouto grinned. "Yeah sorta."

Itachi smiled slightly at the young boy.

"What color do you think it is?" Itachi asked.

Sasuke looked at the moon again. "White."

Itachi smiled and patted his little brother on the head.
