A/N: Something I've had on my mind for a long time.

Laser dot trembling on his head. Breathing in deeply. And silence. Nate could feel his heart beat. He pulled the trigger, with a bit sadistic half-smile. As in slow-motion he saw the bullet fly and pierce his skull. Brain matter flew around. Blue Suns helmets have no effect against the Mantis. Another merc walked into view, confused.

"Assassin!" he screamed out.

That's what Nate was. A murderer. A cold-blooded killer. A precicision mercenary. He was barely an adult, but the slums of Omega teach you to fight.

He focused his attention on the Blue Suns camp again. The one who had found the body was in the process of radioing for help. 'He should pay more attention' thought Nate. The reason to this thought hid in the shadows behind the lone mercenary. A Drell. With a lightning quick move he grabbed the soldier into a headlock and shot him twice in the back of his head.

That was Thane. Nate remembered the moment they met. It was Omega, two years ago. The boy was sneaking around the rooftops. Hoping to find money, food. His parents had been killed by some raging Batarian terrorists years ago. As he was walking on top of a building, he spotted a shadow moving around the corner. It was uncommon to see anyone else up there, as a wrong move would mean plummeting to death, into the space and vacuum. Nate decided to see who was the owner of the shadow. Just out of curiousity. He carefully peeked around the corner. What he saw shocked him: a hooded figure lying on the roof with a sniper rifle in his hand. He looked mysterious. Could be worth a talk. So he waited. Nate was not the one to get scared easily. He just crossed his arms and stood there. The hooded figure kept moveless for a good fifteen minutes. Finally he took the shot. The weapon appeared to be silenced. Against the regulations, even on Omega. The Assassin seemed to observe the situation for a while and finally stood up and turned to the boy.

"Yes?" he asked in a calm tone.

"I saw you," Nate stated, voice a bit trembling.

"I know. Anything you want?"

He knew that there was no way of him getting out of this mess alive. He had spotted an assassin killing someone. He was as good as dead. So why not take a chance? He had nothing to lose.

He collected his thoughts and asked emotionlessly: "Could you train me?" He had killed before. Vorcha trying to rob him. Batarians who had killed his mother and father.

To his surprise, the drell didn't draw a weapon. He just stood there. Taken completely by surprise by the question.

"If that's what you want," he finally answered.

Nate slipped away from the memories. Thane was dragging the bodies away, into the shadows. The roof he was on wasn't far. Not far, but a lot higher. Time to take the risk. He took his Mantis with him and vaulted over the edge. The ground was nearing with scary speed. At the last twenty meters he started slowing himself with biotics. He had recieved an implant from the Alliance. After Thane had taken him student, the Drell took him to the nearest Alliance station. There he enlisted and served for a year. Biotic talent was discovered and L4 implants were given. He bribed some important people (with the money coming from Krios) to go into reserve, not serve in active military and here he was now. On another contract for Liara T'soni. Nate liked her way of business, they were quite good friends.

Nate landed with a big boom. A crater was left, but he himself was unharmed. Thane didn't even react to him appearing. The young assassin caught up to the older and side-to-side, heavy pistols drawn, they moved onto the camp.

A guard spotted the pair. He didn't even stand a chance. Nate took careful aim and shot him clean trough the head. The bang alerted all the others though, and there they were. Blue Suns of Illium. It's leaders anyway. Thane grabbed for his pouch and sent a flashbang flying. It exploded with a big, ear aching bang and a blinding flash. Nate knew to expect it and turned away, but most of the shocked mercs were blinded. Thane moved on. With an acrobatic kick he finished off a shotgunner, then gracefully moved onto another. Nate drew another one of his pistols and wielded them Akimbo-style.

He ran forward. One of the leaders was regaining vision. He raised a rocket launcher. 'Where do these guys get all these guns' he thought. The assassin threw himself into a slide and narrowly dodged a rocket shot at him.

Left trigger.
Right trigger.
Left trigger.
Both triggers.

Nate shot furiously. Three Blue Suns remained. Thane appeared and punched one from the front in the neck, so he collapsed as his neck was certainly broken and the man dead. Nate took out a knife. He aimed it at one of the two survivors and threw it.

Headshot.

Thane performed another.

Contract complete.
