(I don't own any characters etc etc)
Iruka smiled and waved as the last student left, then sighed and rolled his shoulders.
"I know you're there," he said as he began to clean his blackboard.
"Afternoon, sensei," a voice drawled as its owner gracefully climbed through a window. "You take all the fun out of spying sometimes."
Iruka paused and rolled his eyes. "It's not spying if my classroom wards detected you. And I asked you to come here," he said, shaking his head as he resumed cleaning.
He turned around a moment later to find the copy nin leaning against the door, arms crossed.
"Would you like to have a seat?" Iruka asked, and the other man shook his head.
"Fine," Iruka sighed, sitting in his own chair. "I'll get right to it then. Naruto told me about the...fireside stories...exchanged during Team Seven's last mission."
Kakashi stared at him blankly, and Iruka continued.
"I can't say I approve of them, Kakashi-sensei."
Kakashi shrugged. "It was all in good fun, sensei."
"All in good fun?" Iruka asked, raising his voice. "You've gotten him all worked up about it!"
"Maa, about what?"
Iruka blinked at him several times. "Seriously?"
Iruka shook his head. "You know exactly what I'm talking about. Now, thanks to you, I've got all these extra....plans...with Naruto, for the next month! And you," he said, pointing at the copy nin, "you're helping with everything!"
"Are you inviting me to spend the holidays with you and Naruto?" Kakashi asked, surprised.
"No!" Iruka shouted. "I'm demanding you accept responsibility for telling Naruto that Santa Claus is a missing nin who wears a red uniform and is going to infiltrate the village one night! Now Naruto has all these plans on how we should protect my apartment, as well as the whole village, and how to use these new holiday customs that are coming into the village to trap Santa!"
Kakashi blinked at him. "You're not actually serious?"
"I am, and so is he."
"But, it was just a joke," Kakashi pointed out. "Sakura didn't take it seriously, nor did Sasuke."
Iruka pinched the bridge of his nose. "Sakura is smarter than that. So is Sasuke, though I expect Naruto will rope him into all this. Probably her as well..."
Kakashi chuckled, and Iruka glared at him.
"I'm glad you're finding this so amusing, Kakashi-sensei."
"I am, sensei, oh, I am."
Iruka shook his head and stood up. "Well, you can't say I didn't warn you. Thanks to all this I'm spending any free time this weekend with Naruto planning on which of the winter holiday events and customs we should pursue, and how to monitor and trap the 'missing nin'."
"Well, he's putting his knowledge to the test," Kakashi pointed out.
"He's just a child!" Iruka shouted. "Let him enjoy winter and its holidays! If he wants to pretend Santa is real, and not a missing nin or enemy, let him!"
Kakashi stood straight, away from the wall, and studied Iruka with a measured gaze. "He is no longer just a child, sensei," the copy nin said in a stern tone. "He is now my soldier, and he will be treated as such."
They stared at each other in silence for a moment.
"Let him be your soldier after the new year," Iruka said. "For this holiday season, he can be a child. You can argue with me about it next year. We'll be in touch about our plans."
Kakashi studied him in silence for a moment again before leaving in a swirl of leaves, and Iruka exhaled.
"Stupid jonin telling scary stories," he muttered to himself. "As if!"
