Dean Surveyed the ruined corpse, immediately noting the missing heart, and the ripped flesh. He also noticed how the body was strewn around a 30ft crime scene, as if the motherfucker had shaken the body in his teeth, as a dog would a chew toy.

It was like a werewolf on steroids. Awesome thought Dean grimacing.

Dean turned to voice his complaints to Sam, but found him staring gob smacked in the opposite direction. As if this massacred body wasn't the most interesting thing here. Dean turned his gaze toward where Sam was looking and his eyes widened. Was that Gunny?

Agent Gibbs had finished signing a release form, so the body could be transported back to Ducky's autopsy lab. He turned around to be met with two pairs of very familiar eyes, one sea green, the other pair a warm brown one. Gibbs was very rarely surprised, but seeing John's boys live, in the flesh after 15 years gave him quite a shock.

"Gunny?!" Called Sam and Dean incredulously at the same time. Gibbs' face stretched into an un-characteristic smile and he strode over to where the two men were standing. Tony looked upon the scene in front of him in shock. It looked as though his boss knew those young FBI agents, and actually liked them. Weirder still, they called him Gunny, a name Tony only knew to be used by his boss's fellow marines, or very close friends (there weren't many of the latter at least).

Sam regained his cool the quickest.

" Hello there agent Gibbs, as you might remember this is agent James Wilson and I'm Agent Aaron Sully." Sam said enunciating their names, as if the NCIS agent might call them by something else. That was the first thing Tony noticed that was strange.

" I remember " replied Gibbs, with a knowing look in his eyes.

John's boys essentially looked quite similar to their young teenage selves, although Sam was definitely taller (he imagined this bugged Dean quite a lot) and they were more muscular for sure. The main difference Gibbs noted was in the eyes. Each of the men's eyes contained knowledge, pain, suffering, and experience far beyond their age. He remembered how Dean had been at the mere age of 15 (the last time they'd seen each other) already a young soldier. Gibbs knowing Dean well (much better of the two) knew how much more pain he would be concealing, hidden behind a careful façade of humour and sarcasm.

The men carried themselves like marines would only more casual, with less of the rigid movement and preciseness a man in the force would. Gibbs knew that shouldn't fool him, the boys were as trained as anyone in the forces, they were just more used to blending in.

Dean Grinned widely, making him look much younger.

"So how is John?" Gibbs inquired. He hadn't spoken to John since he'd last seen Sam and Dean. Dean's smile faded, and his mask slipped a little, his eyes showing an immeasurable amount of guilt and pain. Gibbs already knew, at that point.

"Passed away in a Hunting accident a while back." Sam said sadly.

Agent Gibbs felt a wave of emotion pass over him. He and John and had their various disagreements specifically over the way he was raising his sons, but they'd always been close. He somehow knew it would always have ended like that.

Flash Back:

"I know it's not fair on them damn it!" John shouted "Gunny, I know." John's face crumpled from it's angry mask showing only hopelessness and guilt.

"But what else can I do?"

"John you lost Mary, and I know nothing will fix that. Nothing. Revenge won't fix it, guilt won't. But those boys shouldn't be raised like this, they're good kids. Hell, they should be focused on school, Deans barely scraping a C and you know he's smart." Gibbs said frustrated.

"I have to find this thing Gunny, for Mary I have to" John said resolved.

"It'll kill all of you John. Whether or not it kills you physically it will eat up inside of you until you might as well be dead. You're sons deserve better." Gibbs replied angrily.

" They deserve to know that whatever killed their mom is gone." John yelled back.

They glared at each other, neither one backing down.

Gibbs sighed. Despite everything he really hoped that John had avenged his wife before he'd been killed.

" So, a federal agent now?" Dean asked disbelievingly.

Agent Gibbs laughed.

" Sort of. NCIS investigates Crime within the Marines and it's personnel. We're not FBI, if that's what you mean, in fact we don't like the FBI much at all." Gibbs nodded at them knowingly.

" I guess that's OK" Dean chuckled. "What's with very special agent inquisitiveness over there?"

"Tony's a good agent" Gibbs stated firmly, "he actually reminds me a bit of you."

Dean raised one eyebrow, when he had been talking to the agent he had seemed serious and annoyed. Maybe though it was because they were impersonating FBI and from what he heard from Gunny, NCIS didn't like them much. We'll have to see how it goes, Dean decided.
