Marty Deeks:NCIS Los Angeles

Marty was first introduced to NCIS:Los Angeles in Series 1. I remember he was under cover as a boxer for the LAPD.
When a lance Corporal is found dead Sam also goes in as a undercover boxer. Both Sam and Deeks were trying to compete against each other without knowing they were on the same side. When the are both picked up and locked up for fighting on the street it is revealed that they are on the same side. Deeks saves Sam life when Sams cover is blown.This was episode 19. He then played in one more episode of series ! before going deep undercover for the LAPD
Since the beginning of Series 2 Marty has been a regular as the is the NCIS / LAPD Liaison Officer.

Here is what we know on Marty

Marty I think has been a valuable asset to the team. Although at first he wasn't taken seriously as a new member of the team, mainly by Sam because of Dom a young Anent killed on the job, he managed to settle in quite well. He still is the subject of a lot of jokes and ridicule which he takes in his stride.
He still has a lot to learn when it comes to the team and their ways of doing things but when things have to be done he does them. He seems to have a fondness to Kensi especially, there is flirting and teasing going on and the way they look at each other sometimes gives you the feeling that they have feelings for each other, whether that be romantic or a brother-sister thing I am not sure as yet. He has a special bond for Hetty as well. When he was stuck in an episode and everyone thought he was dead Hetty was the only one he could feel he could trust so he called her instead of his bosses. He has a lot of respect for Callen and Sam due to their experience, but doesn't mind throwing a smart remark their way when ever he can. In each episode you can hear Marty saying "Really? or "Seriously?" which seem to be his trade mark
In the episode "Anonymous" (season 2 ep 7) Deeks walks in just as Kensi and Sam finish training where Kensi had tasered Sam a few times (but they only faked it) But as she walks past Marty she tasers him for real and holds the button down leaving him with a burn mark the next day.
