Yamamoto-soutaichou didn't bother to look up at the disturbance outside. If it was important, someone would come and tell him.

"There's a man outside to see you, sir," his vice-captain said, appearing on schedule. "He, um, appeared out of a blue box."

"Blue?" Yamamoto enquired.

"Blue," his subordinate confirmed.

"Show him in," Yamamoto instructed. "And bring tea."

"About time too," the old man said fussily. He seated himself opposite Yamamoto. "Was I expected?"

"You said you would be coming," Yamamoto nodded. "But it was a later version of you."

"Oh." The old man frowned. "I really shouldn't have done that."
