I know that Deeks losing his memory has been done before, but this is a different take on it. It takes place in Season 5 while Kensi is in Afghanistan.

The day started out like any other day with Kensi gone. Callen and Sam try to include Marty in activities but he declines. Actually he is pushing them away. With Kensi here, he would be with her. But now he just feels alone.

He gets up at the crack of dawn which is easy since he isn't sleeping much anyway. He hasn't been surfing much either, his heart just isn't it. Kensi was the only one he ever let in and with our her, his heart is breaking. Well, the only girl he let in anyway. Ray is his best friend, but he is gone, disappeared into WitSec. His other best friend has a busy life and no time for him.

Marty walks into Ops at 6:30 in the morning to began the paperwork from yesterday's case. 2 hours later Sam and Callen walk into the building teasing each other as they have always done. They should have been shocked to see Marty already hard at work, but they weren't. The bags under his eyes becoming darker.

"Deeks, what time did you get up this morning?" Callen asks.

Without looking at them he answers "5:30"

"And what time did you go to bed?" Sam inquires.

"I don't see how that is any of your business." Marty answers and levels for the shooting range.

Callen and Sam have been getting really worried about him. They see the effect that Kensi's departure is having on him. They hope she returns soon for Marty's sake.

With as bad as things are getting, when there is a case. Marty is his usual self, doing whatever it takes to get the job done. That is probably one of the reasons, that Hetty and Callen haven't benched him.

No one knows what really happened. Sam, Callen and Marty arrive at the suspect's house. As they approach the house it blows. The force of the explosion sends them flying.

Sam comes to first. He checks his surrounding. The house is gone, a few feet from him Callen is beginning to come to. Sam races over to help him up.

"You good?" Sam asks.

"I think so. What about you?"

"I'm alright." Sam responds. They look around and don't see Marty anywhere.

"Deeks!" They call out together.

No response. They start searching for him. They do find him unconscious with a head wound. By the amount of blood surrounding his head, he must have cracked his head open when he hit the ground.

"Eric call for an ambulance! Deeks is hurt." Callen calls out.

At the hospital Callen and Sam are in the waiting room waiting for answers about their teammate. They hear a voice.

"I'm looking for Marty Deeks. I was told he was brought here."

Sam and Callen look to see who the voice belongs to. They are shock to see that it belongs to Kip Brigham.. A hot shot basketball player who leads the league in scoring.

How does he know Marty? Why is he here?

"You are Kip Brigham. How do you know Marty?" Callen asks.

Before Kip could respond the doctor interrupts.

"I am Dr. Casey. Marty has a severe concussion but he is awake. What is concerning me the most is that he think he is eleven years old, but he has total amnesia."

Sam, Callen and Kip stood there in shock. This was not what they were expecting to happen when the day began.
