My first attempt at an AR/NCIS crossover, and I hope you guys like it. For once, I have no idea how long this will be, but it should be longer than my previous fanfics. R&R! ~ SamayouTamashi

Timothy McGee, Anthony Dinozzo and Ziva David were rudely awoken in their homes to the sounds of their phones ringing. When they picked up, it was Leroy Jethro Gibbs calling them to work at three in the morning.

McGee scrambled to his feet, closing his cell and sliding it into the bag by his bed. He flung on some clothes, hoping they matched, shut off the laptop that had been left running during the night, and made it out the door in a record five minutes. When Gibbs calls, you drop everything without asking for an explanation.

Dinozzo was a bit slower to answer the call. He flicked his phone shut and laid back against his pillows grumbling, "Five more minutes." An hour later, Tony was yawning as he searched for his keys on the tabletop by his head.

Ziva was waiting for them when the two stumbled tiredly in, looking as if she had been awake the whole time. Three coffees were on the desk in front of her. Already assuming that 'Ninja David' had teleported to the office before the call had even come in, they gratefully accepted the caffeine. "Where's the boss?" Tony asked. "Don't tell me he played an April Fool's joke on us."

From out of nowhere, the agent felt the Gibbs-slap take him by surprise—as it always did—as Gibbs entered the area. "It's November, Tony."

"I knew that, boss," he winced, feeling the brain cells in his head dying slow painful deaths one by one.

"Suit up. We have a dead marine waiting," Gibbs ignored Tony's well-deserved pain. "McGee, I need you to pick up Ducky. His brakes have broken down and he's going to need a ride."

"Do you remember what you were doing here, son?" an older officer from the local police department was asking a teenager sitting on the curb as the trio walked up to the crime scene. The boy was shaking his head, a confused expression on his face. Ziva stood over the officer's shoulder. "A witness?" she asked.

The officer turned to look at her and shrugged. "There were shots reported in the area and when we found him," he pointed at the body sprawled further back in the trees, "there was this boy standing over him. He says that he has no idea why he came here, how he got here, or even where he is in the first place."

Taking in the blood-splatter covering the side of the teenager's face and torso, Gibbs sat down next to him. "Do you know your name?"

With a frown, the boy whispered, "I…I can't remember anything, but…it might have started with an 'a' or something. I wish I could help you," he added with a dismal droop of the shoulders.

"We'll help you along, don't worry." Gibbs patted his shoulders. "Do you have a phone or something on you that might have an address or number for your parents?"

He patted his pockets and peeked inside the pockets of his jacket, but shook his head again. "Nothing. Wait…" From out of one pocket, he pulled out a slip of paper and handed it to Gibbs. "A plane ticket, I think."

"No less, it's a two-way ticket from London to D.C. This is a good lead, and I can have one of my agents see who was on this flight. It explains your accents, as well."

"Thanks." The boy looked down at his shoulders, apparently building up his courage as he stared back determinedly at the NCIS senior agent. "Until then, can I follow you on this case? I…I don't know why I was here, but I get the feeling that my past is connected to him," he said, gesturing at the corpse behind Ziva. "I think that…" The boy grimaced as he seemed to catch a glimpse of what he'd lost.

Gibbs urged him on, "What do you remember?"

"I think that I might have killed him."

A/N: Sorry about the cliff-hanger, but I'm infamous for them. The reason it's so short is because this is a prologue and teaser…and because the freezing rain and wind might knock the power off again.

Cookies (not really) for anyone who can correctly guess where the title comes from! ^_^
