It's just a little one-shot to a song called "Say Something" from A Great Big World. It was in my head and I just needed to get it out.
Even though it's sad I hope you like it.

He thought he would be happy. He thought he would be happy to see her alive and safe. Kensi. The Kensi he fell in love with and haven't seen her in months. The one girl he wanted to spend the rest of his life with. And no he's home. Alone.

Say something, I'm giving up on you
I'll be the one, if you want me to
Anywhere I would've followed you
Say something, I'm giving up on you

When he heard that they were going to Afghanistan he was scared and angry. Scared that he would never see her again. And angry because it was Hetty who sent her away. Away from him.
He has done everything there to help is team to get her back. More than he thought he would be capable to do. He tortured a blind man. He tortured a man and the second he did it he remembered what it was like. To sit in a chair and fear of his life. That was the moment where all his strength left him. He kneeled beside the chair, desperately begging for forgiveness even though the man couldn't understand him. That was the moment that he realized he would nearly do everything to get Kensi back.

And I am feeling so small
It was over my head
I know nothing at all

And I will stumble and fall
I'm still learning to love
Just starting to crawl

And then they got her back. He helped and probably saved his whole team but that wasn't important because he would be finally able to see her again. When he walked through the desert with the man in front of him he realized that she was not alone. That he knew the guy next to her. Not personally but from a picture Kensi had showed him one time. Jack. Jack her ex-fiancé who left her alone and broke her heart.

Say something, I'm giving up on you
I'm sorry that I couldn't get to you
Anywhere I would've followed you
Say something, I'm giving up on you

He would fly with them. Of course Jack had to fly with them. The whole time Kensi was sitting beside him as if she was scared that he would disappear any second. She was hugging him, speaking with him and always touching his shoulder or his arm but the worst was that she was ignoring him.
Even Sam and Callen came to him to ask if everything was alright with him. Of course everything was alright. His partner and almost girlfriend got kidnapped in Afghanistan, he nearly killed an old blind man because he was so desperate to get her back, after that he had a breakdown and now his partner sitting next to her ex-fiancé and is ignoring her. So what should be wrong? And like always he smiled and said he was fine.

And I will swallow my pride
You're the one that I love
And I'm saying goodbye

It were now nearly two weeks. Two weeks the whole team got off to recover and even though that he had left multiple messages and wrote her several sms he'd never got an answer. He was sitting alone at home with Monty talking to him or crying himself to sleep.

Say something, I'm giving up on you
And I'm sorry that I couldn't get to you
And anywhere I would've followed you
Say something, I'm giving up on you

He knew that he lost her to Jack the first time he saw her again. The first morning that they had to come back to work and she was driving with him laughing about something he said. He noticed how Sam and Callen looked at him trying to say that they are sorry but at the same time happy to see her smiling again.

Say something, I'm giving up on you
Say something...

After everyone left he said Hetty that he was going back to the LAPD and put a notice on Kensi's desk.

Dear Fern,
it was very nice to meet you but I have to leave.
I wish you the best and hope you'll be happy.
Love Max
