One Last Time

"Seto…." a small voice reached the elder Kaiba's ears as he was just getting ready to power down his computer. It was well past midnight, and Seto knew he needed to get some sleep for tomorrow.

"What is it, Mokuba?" he asked without having to look over at his baby brother. Actually, Mokuba wasn't much of a baby anymore. In fact, it was know his 13th birthday.

The younger brother didn't answer, but merely made his way over to the desk and climbed into the extra chair (kept there especially for occasions such as these). Seto finished shutting off the machine in front of him before turning to face his brother.

"It's late, Mokuba. You should be in bed, or else you'll be ornery all day tomorrow."

"Don't you mean today?" the younger asked as a nearby clock chimed 1 AM.

"You know what I mean," Seto answered, getting a bit annoyed at his brother's cryptic behavior, "Now, what do you want?"

"Can I sleep with you?" Mokuba said quickly, as though he wanted to get it out before he lost the nerve.

"Why? Are you having nightmares again?"

"No, it's just…" the younger Kaiba let his voice trail off while his brother waited patiently, "I want to… one last time," he added, looking at his feet to try to hide his flaming blush.

Seto was quite taken aback. He never thought about when the nights his younger brother would crawl into bed with him after a terrifying nightmare would stop. He never told Mokuba, but he drew as much comfort from Mokuba's small body, pressed tight against him with tiny arms wrapped around his waist, as Mokuba drew from him. He would just have to adjust to those times coming to an end.

"Seto…?"

His younger brother's soft voice made Seto realize he hadn't said anything. He mentally shook himself and looked down into the soft grey-blue eyes, allowing a gentle smile to play with his mouth.

"Of course you can. Go get in your pajamas."

"Thank you, Seto!" Mokuba said and turned to run across the hall to his own room.

'He's really growing up,' Seto thought as he watched his brother go, 'and there's nothing I can do about it.'

It was that final thought that scared him the most.
