Lost Chapter:

"Okay," Kakashi said, "I'll try it, but I don't think it's going to work." Kakashi formed a familiar sequence of hand signs. Summoning Justu. Pakkun appeared in a puff of smoke.

"What's up Kakashi?" Pakkun asked, looking around. The ninja seemed relaxed so Pakkun, relieved, relaxed too. This was a pleasant surprise. So many times during the war Pakkun would find himself being summoned into the middle of a battle or worse, when Kakashi was injured and needed him to get help. This might just be something simple.

"Pakkun," Kakashi said, right down to business. "We're looking for a wizard that might be trying to infiltrate this school. His name is Sirius Black."

Pakkun observed the stone walls around him. They were assembled in the room in which the ninja had been living at Hogwarts. "We're in a school?"

"Yes, for wizards," Kakashi replied.

"Right, okay then," Pakkun accepted this even though it sounded crazy. Kakashi rarely joked with his hounds.

"Any way you could sniff Black out for us?"

"Sure thing," Pakkun said and waited. When Kakashi didn't move, he looked at Kurenai, Guy, and Ebisu in turn. "Where is it?" The hound pressed.

"Where's what?" Kurenai asked.

"Whatever it is that has this guy's scent on it," Pakkun said with mock patience.

Everyone looked at him disbelievingly except for Kakashi. "Can't you just," Ebisu gestured with his hands, "sniff him out?"

"With what to go on? Do you think this guy's name has a smell attached to it that I can just tap into?"

"Well, he's a wizard, an adult wizard," Guy said helplessly.

"So you want me to sniff out a wizard in a school for wizards?" Pakkun deadpanned.

"Well he probably hasn't bathed in awhile," Kurenai said thoughtfully.

"Great, I'll just ask all-" the hound looked at Kakashi.

"About 850 wizards and witches plus the magical creatures that live in and around the castle," the jonin supplied.

Pakkun nodded, "I'll just ask all 850 people who live here what their hygiene route is and track down whoever smells the worst. I'll get right on that." The hound didn't move.

"But he was just here," Ebisu exclaimed. "We know he was in the Gryffindor common room."

Pakkun turned to Ebisu. "How is one scent out of dozens, even when he was just there, supposed to mean anything to me? I've never smelled anyone in this school before except you four."

Ebisu was slack-jawed.

"Maybe I should sniff everyone in the castle and then hunt down the one scent that doesn't belong."

Ebisu almost started nodding thoughtfully.

"Do you know how long a summons lasts?" Pakkun barked at Ebisu. "Not. That. Long."

Ebisu cringed a little at the tiny ball of fury.

Guy still had faith, "but you're a ninja hound!"

"Ninja hound yes," Pakkun said, "magic nose? No."

"If you guys get a piece of clothing or a shoe or something this guy owns for me to sniff then I'll be there. But until then, I believe Kakashi promised us a break now that the war is over."

Kakashi nodded, "thanks anyway Pakkun." The hound poofed back to his own world. "Do you believe me now? Do we need to have any more talks or explanations?"

The three ninja shook their heads. Ebisu in particular looked dejected.

"Good, then I guess we'll just have to protect the students without outside help," Kakashi said. "Fan out."

Author's Note: I wrote this up in response to some reviewers who were wondering why Kakashi didn't just have Pakkun sniff Black out. I hope my reasoning was clear and to your satisfaction.
