A/N; A Criminal Minds X CSI: Miami crossover that brings the BAU to Boston, when it is believed a CSI was the failed target of their UnSub, who hadn't been successful in killing him. Luke realizes his personal connection to the case. Oneshot?

(This is my first story written that involves Criminal Minds, so I do apologize for any mistakes or OOC moments. I wanted to try something different.)

Story Notes/Help to understand the storyline: Eric suffers from mild amnesia, and he forgets a lot after the shooting. Including his past. So when he gains some level of stability, he is reintroduced as Luke Alvez - given a new identity and a chance to start over. Throughout the story, he begins to regain old memories and kinda recognize who he'd once been.

Special Agent Luke Alvez had accompanied the latest victim of the UnSub the team had been tracking down to the hospital. He'd survived it all. It was very unusual.. for the victim to live. But he'd fought the hardship, being on the brink of his last few heartbeats. Every other victim died at an instant.. except for him. Their UnSub had suddenly had a random change in M.O. which was most definitely irregular, unless the killer was caught in a panic and didn't have the time to check if he was dead before they'd fled the scene. Then again - that was just a theory. There was truly no textbook explanation for a serial killer's altering.

The team had gotten the call from Boston PD, saying that the unknown DNA from their crime scene matched the samples they suspected belong to their UnSub. So they were in Boston with the hope of finally catching them.

The latino had experienced an odd connection to the victim, which made him feel as though he needed to know the guy was okay. They didn't even have his name, however, Alvez felt like he knew him from somewhere. He sat in the hospital waiting room, anxiously awaiting a result. A nurse informed him that he had endured blunt force trauma that could induce temporary, or permanent, memory loss. Nobody could be to sure as to what he would remember and what he wouldn't. As much as it for was for professional business, Luke also felt as though he might have a personal connection to the case. He'd lost a lot of people in his life. Had to start over, and begin a life with nobody but himself involved in. And the worst part was - nobody would ever know the old him.

He received a call from JJ as he impatiently paced up and down in wait of the results. "Hello?"

"Luke, the victim's name is Ryan Wolfe. He's a cop from Boston PD, supervisory CSI."

"Ok, thanks JJ."

Even though he thanked his teammate, it felt like he'd known the man's identity anyhow. Ryan Wolfe. Luke let the name sank in as he waited. He was having blurry flashbacks. A hand on his. Driving furiously through the streets of Miami. Wolfe. Luke didn't quite know how Officer Wolfe fitted into it all, nonetheless, he was involved.

JJ had pondered Luke's instinct to tend to the victim's side as quickly as he had. She didn't want Internal Affairs getting the wrong impression again. Whatever connection Luke had to Ryan Wolfe, she hoped it wouldn't cloud his judgement during the case.. or else it could lead to him being benched. She trusted Alvez though. And knew that all his actions had reasoning behind them, despite how dangerous and insensitive they may seem to others.

'WOLFE!'

He could hear the lost memories as they played through his head. Getting shot. His life flashing before his eyes. Like a lost part of him that he couldn't quite recall.

The faint sounds of the beeping of an unstable heart monitor. People shouting. Blurs of people he once knew looking down upon him. A name that wasn't his being shouted over and over. "Mr Alvez." A nurse's voice had broken off his frozen state of confusion.

"Yes?"

"Ryan Wolfe is out of surgery. You said you wanted to be the first person to know."

Alvez stood up, wiping his forehead and letting out a sigh. The nurse led him down a few different twists and turns through the building, until they reached a room where the woman stopped. She carefully pushed the door open and Luke finally got to see the younger man again. "We think he's got good memory, although, there may be things missing." "Thank you."

She left the room and Luke hesitantly approached the hospital bed. "You.. don't remember me.. do you?"

"Aha.. not really."

He gave a drowsy nod. "It's ok. I suppose it means you don't know who Eric Delko is?"

Eric Delko. 38, almost 39 years old currently. Left Miami, and went completely off the radar. A Drug I.D. & Fingerprints expert. Car enthusiast. A CSI.

Luke swallowed his slight anxiety and got his notepad out as he had to get back to the case. "Wolfe.. what do you remember from being attacked?"

Ryan exhaled deeply. "This guy came up to me.. tried to kill me with a 38 caliber. I got pistol whipped.. so I fought with him and scratched him.. then he disappears and all I see is the.. shadow of a plank of wood.."

"You've got your attacker's DNA underneath your fingernails."

"I know.." The CSI tilted his head up as he heard the stampede of footsteps on the floor above. "God, I hate hospitals."

"I remember." Luke subconsciously replied.

Even when drowsy from the anaesthetic, he'd not missed any of the words Luke had said. But it was that response in particular that threw him off. Of course, Wolfe knew the truth.. but he'd not wanted to confuse the guy.

"I need to make a call, but I'll be right back.." Luke told the CSI, rubbing his shoulder before he left and got his phone out.

Alvez phoned Emily and updated her on Ryan's statement. Prentiss was happy that the victim had been able to offer such valid information after an attack as brutal as that. ".. How are you doing, Luke?" "I.. need some time to think."

"Ok, well, we are here if you have any problems."

"Yeah, ok. Thank you."

The latino shoved his phone back into his pocket and re-entered the hospital room. "Eric.." He mumbled as he heard the door. Luke froze. Eric.

"What was.. Eric like?"

Ryan nodded. "Eric's birthday is May 18th, 1976. He loves cars, sports, the occasional beer, takeaways and action movies.."

Alvez sat in the chair beside the injured CSI, listening to his hoarse voice as he talked about one Eric Delko he once knew. "..He hates when people mess with the people he cares about. When I got shot with a nailgun.. Eric had been the person to recklessly drive me to the hospital. He also hates Internal Affairs.. and tea.. He always said it just didn't taste right.."

It all brought him back to Miami.

"Sounds like you know a lot about him." Luke commented nonchalantly.

"It took me.. a while.. to figure him out." Ryan admitted as his hazel eyes finally focused on his brown ones. He remembered those eyes anywhere. "..but I cared about him really. We had this.. almost friendship thing.."

That smallpart of him was flattered. Completely stunned by his emotional response the mention of the CSI. Ryan didn't have to say the things he did. Or even study him the way he had. But his attention to detail was not was lacking as he'd previously thought.

Luke was conflicted. Was Alvez his alter-ego, or his real self in the form of another name and an altered background?

"The DNA.. should be sent back to the lab to get a match.. You should go. I'm sure your team is waiting for you, Alvez.."

Ryan was right. He had all the verbal proceedings he'd get from staying with him at hospital. The latino lay his hand on his shoulder, not breaking off the eye contact with the CSI. "We're going to find who did this to you." He quietly assured him.

"Thank you." Wolfe mouthed, a small smile forming upon his face.

He weakly lifted his right hand and placed it onto the agent's. "Suppose.. I'll see you 'round sometime..?"

"I guess so."

Luke and Ryan ended the slightly sappy moment, the FBI agent standing up and walking towards the door. Wolfe watched silently. He had felt so much more at ease to just be face to face with the Cuban again. Now he had reassurance that he was still alive. Still living. And he was good. Really good. Wolfe knew Eric had been through hell and back with the memory loss.. but he could tell that the older man was remembering again. That made him feel a lot better. Knowing that eventually he would no longer be kept in the dark about his Miami past.

As the latino headed for the door, both men couldn't get one thought out of their heads; what did happen to Eric?

"And Luke.." Ryan said as the FBI agent had his hand on the handle.

Luke turned to the CSI with curiosity. "Yes?" Ryan attempted to suppress a grin. "Happy Birthday.. you're almost..the big 4-0.."

Alvez gave an expression of mock offense. "Thanks, Ryan. Get well soon, bud."

"Thank you.." He paused. Ryan had a brief moment of doubt in what to call the Cuban. "Eric."

"..You're welcome, Wolfe. Stay safe, brother."

"You know I try." He winked.

Luke chuckled, leaving the room for the definite last time. On his way back to Boston PD to report on Ryan's condition and what he had, he thought about everything the younger man had said. It played in his mind as he came to terms with it all.

Ryan had been the key to finding his past. Obtaining old memories and relearning all the things he had known before the shot to his head. I'm living on a piece of metal.

Thank you, Wolfe. Thank you for helping me remember what is trying to be forgotten. I still remember things about you. Like you're OCD, and you live on coffee.

Once the investigation came to an end, Luke would look into more detail about it. For now though, he was just glad to have some form of closure about his past.

"Sure you're good?" Matt asked Luke as he joined him and Rossi in Boston PD's conference room. "I'll be fine." He replied, smiling as he thought of his friend.

"That's all we wanted to hear. What'cha get from our vic?"

"A lot."
