AN: I have always seen Derek as an Alpha Male. Everyone knows that, but what everyone doesn't know is the sexually dominant side of Derek, including Garcia, who is keeping a secret of her own.

Derek could barely contain himself. What the HELL was Kevin doing in Garcia's apartment? He had tried to be understanding about Kevin's lingering feelings for Garcia, but Kevin's constant attempts to maintain an inappropriate closeness with Garcia was seriously grating on Morgan's nerves. Morgan quietly seethed as he watched Garcia give Kevin a friendly hug and pat on the back in an attempt to soothe him. At that sight, Morgan felt his temper flare. Kevin had no right to touch Garcia, especially since she was Morgan's woman and Derek Morgan did NOT share. Kevin needed to back away immediately and Garcia needed to stop cuddling him. It only encouraged Kevin's demented illusion that he could win her back. She had chosen Morgan and there was no turning back, he was never letting her go.

Obviously, he needed to make that clear to them both. First, he was going to have a man to man talk with Kevin Lynch, and try not to smash his face in. Morgan was sure that neither Kevin or Garcia had seen him. Unfortunately, what Morgan saw next made his fist clench at his sides...Kevin was taking advantage of Garcia's caring personality...he was rubbing her back! Oh HELL no! Obviously, that talk could not wait a moment longer.

Morgan quietly went back outside to wait for Kevin to emerg from the apartment building. Kevin walked to his care and put his key in the lock to open the door, unaware that Morgan was quietly approaching.

"Lynch.."

Kevin started, turning around wearing an anxious expression.

"Hey, Morgan, how are..."

"Don't bother with the pleasantries...stay away from Penelope."

"Really, Morgan, Pen and I are friends," Kevin nervously tried to explain.

"No, you are not...Pen is friendly with you...but you have an agenda."

Kevin opens his mouth, but Derek forestalls anything he would have to say.

"Don't..I'm not like you, I hold onto what is mine."

"You have got this all wrong, Derek."

Kevin had always been a tad frightened by Morgan's looks and athletic prowess, it made him feel inadequate. He knew that Morgan had never warmed up to him. Whenever he was in Morgan's presence, he felt Morgan's intense dislike, how he never directly acknowledged Kevin. He often saw Morgan glaring at him whenever he had his arm around Garcia. The resulting uneasiness would have Kevin dropping his arm with a sense of having done something wrong. That, of course, was ridiculous because Penelope was his girlfriend. Unfortunately, Derek made him feel like a third wheel in his own relationship.

Kevin gulped, meeting Derek's eyes. What he saw there made him even more nervous than before. Menace seemed to ooze from Morgan. Morgan placed his hands on the car on either side of Kevin, effectively cutting off any avenue of escape. He leaned forward and spoke in a menacing tone.

"No need for excuses or apologies. I know exactly what you are trying to do, Lynch." "Penelope doesn't see it, but I certainly do."

"B..but, I..I"

"Lynch, I am not going to stand for you sniffing around my woman." "You foolishly lost her." Derek's voice lowered. "She is mine now and I am never letting her go."

Kevin swallowed. "Really, Morgan. She is not a piece of property, you can't own her."

Derek smiled, but it was not particularly warm or friendly. Rather it seemed to promise retribution. Morgan leaned closer, never breaking eye contact.

"She's mine, Kevin. I own her heart and her soul." "She belongs to me in a way she never belonged to you, and you only have yourself to blame for taking her for granted."

Kevin snorted, "As if we ever were alone in the relationship." "You were always there, doing your super agent thing." Kevin raised his head and there was anger and resentment in his eyes, "Calling her constantly and having movie nights, excluding me. You were always a part of the equation, whether I liked it or not."

"Kevin, don't blame me because you didn't know how to keep Penelope happy," Derek taunted. "You just need to know this, I am not you and if you persist in trying to worm your way back, I guarantee you won't like my response." Derek leaned back, letting his arms fall to his sides.

As Kevin stood there, dumbfounded, Morgan turned to walk away.

"What do you think Pen would say about your threats?" Kevin shot back in a smug tone. "What kind of man would she think you are?"

Derek stopped in mid-stride and turned around to face Kevin.

"Penelope knows what kind of man I am. She knows I'm the man who loves her and will always be there for her." "Always." "Kevin, give up, go find another woman. Leave mine alone." "She is off-limits to you. I sincerely hope that I don't need to repeat myself."

With that statement, Derek open the door with his key and entered Garcia's apartment complex.

Kevin watched Derek depart, feeling defeated. He certainly never had a key to Penelope's apartment. He got in his car, and drove away, feeling dejected, and trying to come to terms with the fact that Derek was the man in Penelope's life now. He certainly did not think that Derek was that possessive, but he realized now that Derek would not brook any interference between himself and Penelope.

Kevin shook his head, he had been fooled by the easy grin and casual manner that Derek used as a mask. Derek Morgan would never willingly let Penelope go, that much was for certain. Maybe it was time for a transfer. Kevin did not relish the thought of Derek's eyes boring holes into his back whenever he was in close proximity to Penelope. By the time Kevin reached home, he had almost convinced himself that transferring was totally his own idea.

As Derek walked down the hall towards Garcia's apartment, he was trying to quell the anger he still felt at the memory of Kevin with his arms around Garcia. He should have smashed his face in.

Derek knew that he needed to hold Garcia in his arms, that would calm his anger. He knew that Garcia had never seen his possessive nature. He had lost too many people in his life that he cared about to feel casual about this. She was necessary to him, her open and giving nature the balm that soothed his restless soul.

Morgan realized that Garcia needed to know his secret, the side that he had hidden from her, from everyone. She needed to understand who he was, what he was. As Morgan fitted the key into the door to Garcia's apartment, he knew that tonight was the night that he laid all his cards on the table.
