As Iruka approached the Copy-nin, he felt his temper rising. He had asked Tsunade for an excuse to talk to him, just so he could really give him a piece of his mind.

Iruka had rehearsed in his mind what he was going to say. He was going to point out how irresponsible the jounin was to leave Naruto in the care of a perverted old sage that taught him very dangerous jutsus (even if such sage Was one of the legendary Sannin). Then he was going to scold him why he had shown Sasuke the Chidori without thinking ahead of what he could use it for besides passing the Chunnin exam.

The Chuunin Exam.

Why on earth had he let him make them take it??

Not only had his students been on lethal danger, but also there was another nation involved There had even been the potential for war!
Sasuke and the Chidori had been the center of it.

Yes, Iruka would give the laid-off jounin a piece of his mind!

Kakashi stared at Iruka as he approached. Suddenly some of the anger in the chunnin quelled. The silver-haired ninja was bigger (but not by that far) and definitely stronger. Perhaps he shouldn't start off yelling. After all the Hatake was hissenpai, and it would be disrespectful to not address him as one.

"Hmmm...Hatake-senpai?" Iruka awkwardly started. Kakashi just gave him a lazy nod. "I believe we've met, my name is Umino Iruka and I am Naruto's, Sakura's and Sasuke's former teacher..."

"Yes, I remember you, you were the one who complained when I said they were ready for the Chuunin Exam" Kakashi looked bored out his mind already. This fueled Iruka's anger.

"Well they were not! Never mind the sabotage during the exam! The sand-nin were ready to kill anyone who got in their path, their teammates included! Why that red-haired monster alone---
"Did you come here to harass my teaching skills or to tell me something worthwhile?" Kakashi interrupted.
Iruka stopped short and a blush of wrath crept to his face. "The Hokage wants to see you." He said under his breadth. "How can you not care about the safety of--"
"Alright then, to the Hokage's" the copy-nin vanished in a puff of smoke.

Iruka stood open-mouthed with disbelief for some time. Then he shook his head and promised himself he would mess up Kakashi's file so all the genin missions would fall on him. That rude bastard.

Tsunade looked up as she sensed a sudden appearance, "oh, you're here" She looked down her papers again.
"Is there a specific reason you sent an annoying chunnin to get me?"
"He was standing there, that's all. Now about your mission..."
"I have a mission?" Kakashi raised an eyebrow. "I wasn't aware of that."
"You have one now." Tsunade looked up, her face serious. "Recently it seems that the enemy knows where to expect us and at what time. It's almost as if someone from here in the village was giving them information. However, the enemy does not know who shows up at the mission or what abilities they have, so nothing has gone awry yet. This tells us that if there is a traitor among us, it's probably a Chunnin or a lower rank, that can see the missions filed, but not who takes them. Your job is to find out if there is a traitor and who it is."
"So I get to spy on chuunins?" An idea was forming in silver-haired ninja, and it involved someone with a scar across his face.
"Yes, basically. You start tomorrow, I expect a report by next week."

Back at home, Kakashi made sure that nothing was out of place and then took his mask off. Well wasn't this going to be a fun week.
He now had the perfect opportunity t get back at that annoying git, and he was going to enjoy it.
