AN: Ok, so I thought I could give this a try. It's a Mentalist/NCIS crossover. It contains mainly TIVA, but a bit of Jisbon/Jello as well, and maybe, some Grisby/RigsPelt. I hope you guys enjoy this first chapter and let me know what you think. What you liked of the chapter, what you didn't, what you would like to read, because this first part is done, and although I have a vague idea of what to do, I'm not totally sure yet.

"Hmmm." Patrick Jane hummed.

"What?" Teresa Lisbon asked, exasperated.

"Nothing." The blond consultant replied.

"Then stop humming." She told him.

"Hmmm…" was his answer.

She rolled her eyes.

The truth was, he was watching two members of the NCIS team with interest.

Anthony DiNozzo felt eyes on him, which was not strange, after all he was Tony DiNozzo, boyish charm and charming smile; what worried him was the intensity of the stare. He knew it was not Ziva, she was interviewing the witnesses and their relationship, whatever that was, was still uncertain. They needed time to figure out what was happening between them.

Tony turned around and found the source of his discomfort. A tall, blond, blue-eyed man. He was looking between him and Ziva.

"Can I help you?" Tony asked out loud.

"I'm Patrick Jane, with the CBI." The man answered.

'The CBI, right.' Tony thought. They were working together this case. The reason why the Los Angeles division couldn't take the case remained a mystery to Tony.

The body of a marine had been found and the CBI had been thrown into the case before the man had been identified. Of course, they wanted to be part of the investigation, and of course, Vance had sent his best team. That's how they got there.

Tony didn't like Los Angeles anymore, not after what had happened the last time…

Wait, had he said Patrick Jane?

Patrick Jane?

That was…

Huh.

With a confused glance, Tony looked at him again. Curly and blond hair, different style, wearing a vest, but yeah, it was him, the fake psychic.

"Ok." Tony replied after a few minutes and went back to work.

'How rude, he didn't introduce himself.' Jane thought.

Jane wandered through the crime scene; he couldn't help but watch the rude agent and his exotic partner interact.

He took a look at the crime scene and the body, watching it for a couple of minutes, and decided that it would be way more interesting to watch and tease the two agents than working this case; after all he knew that the girlfriend was the killer…

'Why do they need forensic evidence?'

Two hours later four CBI agents, an annoying consultant, and their four NCIS guests appeared in the bullpen.

"What is he doing?" McGee asked to nobody in particular as Jane lay on his couch.

"It's nap time." Rigsby answered without turning around.

"Nap time? Who naps at eleven in the morning?" An amazed Tony asked.

"Me." Jane replied. "And if you don't mind, I'd like to catch some sleep." He added.

Tony raised an eyebrow. He didn't know why but he had the feeling that working with Patrick Jane would be interesting.

Very interesting.
