A/N: For the prompt: Can you write a story about why Deeks doesn't like to be called Martin?

"So, Martin, I figured I'd be seeing you eventually," the Assistant Principal said, folding his hands and leaning back in his chair. Marty resisted rolling his eyes; it wasn't like he made a habit of getting himself in trouble. Well, at least not enough to land him in the principal's office.

"It's Marty," he replied, tossing his head slightly to get his bangs out of his eyes. He saw Mr. Hayward's hand twitch followed by a barely concealed grimace.

"As I was saying, Martin," Mr. Hayward continued as thought Marty hadn't said anything, but he could have sworn he lingered on his name. "Would you like to explain what happened this morning?"

Marty sighed heavily and considered screwing with him for a while, but he wanted to get out of there as quickly as possible.

"Bobby was picking on a freshman. I stepped in and things got out of hand," he explained in clipped sentences, resisting the urge to throw in a few sarcastic remarks. Hayward stared him down for a moment and then leaned forward in his chair.

Marty had to admit to himself it was vaguely intimidating.

"Out of hand, Martin? You call a broken nose 'out of hand'?" He truly hadn't intended to hurt Bobby and the reminder sent a renewed wave of unease through his stomach. Brushing that aside he said,

"I didn't throw the first punch."

"And I suppose in your mind, that makes it all right, hm?" Hayward asked, shaking his head. "You know, I know all about your past, Martin. I know about your father, I know what you did to him and I know that you see violence as an acceptable method of dealing with your problems."

A surge of anger and something like shame-which he chose not to examine too closely-as Mr. Hayward so casually brought up the trauma of his childhood. He'd tried extremely hard to get beyond that but sometimes it seemed like he never would.

"If you know me so well, Sir, then you should know that my name is Marty Deeks," he told him, not even attempting to conceal his disdain this time. "My mom's the only one who gets to call me Martin."

Hayward chuckled humorously and said, "Ah yes, your mother. I'll be speaking to her when I'm done with you." The derision was clear in his voice and it made Marty's dislike ratchet up to pure loathing.

"What are you going to do with me?" he asked, suddenly eager to get this over with.

"I haven't decided yet." Hayward gestured towards the door. "You may wait in the office until your mother arrives."

Marty pushed himself out of his chair, willing to face the humiliation of being seen by his classmates.

"Oh and Martin," Mr. Hayward called as he reached for the door, "I'll be keeping my eye on you."

A/N: I see this more as one of many incidences that led to Deeks' aversion to being called Martin.
