Darren was bewildered for a moment staring at the door, then at the pen, and then to the mechanic. The mechanic looked at him then back to the pen, then back at him. The mechanic dove for the pen.
Darren's eyes widened and there was a moment's hesitation then he dove for the pen too. Both of them collided and rolled to the floor sending the pen skittering away across the room. Darren tried to push himself back onto his feet to go after the pen but the mechanic grabbed a fistful of his hair and slammed his face into the ground.
There was a loud snap, and he guessed it was probably his nose. He ignored the pain pushing himself to his feet, the mechanic had the pen and was charging at him. He reacted too slowly and the mechanic buried the pen in his left shoulder. Darren cried in pain and swung wildly with his right fist.
He connected solidly with the mechanic's jaw causing the man to take a step back and release his grip on the pen which was still firmly lodged in Darren's shoulder. Darren wasted no time following up his first punch with a second. The mechanic, apparently expecting that, ducked the blow and slammed his own fist into Darren's face.
Darren grabbed the man's arms trying to throw him to the ground but the mechanic easily overpowered him sending Darren sprawling across the floor. The impact with the floor jammed the pen deeper causing another explosion of pain from his shoulder.
The mechanic was crouching over him and he raised a fist and slammed it into Darren's head again. He raised his hand to repeat the motion but Darren managed to move out of the way, the mechanic's hand slammed into the floor.
Darren used the opportunity to grab the man by the shoulders and roll him over. He pinned his arms with his knees and without a second thought he wrapped his hands around the mechanic's throat. The mechanic struggled to get free of Darren's grasp trying to pry his hands off but to no avail. The mechanic's lips began turning blue and Darren only tightened his grip blinking away the blood that was beginning to drip into his eyes.
The mechanic's movements grew more frantic for a moment as he struggled to escape Darren's grasp. Then finally his movements slowed as his face turned blue before altogether stopping. Darren kept a hold of the man's throat for a few minutes after that before it sank in that the man was dead. Slowly he released the mechanic and stood just staring at the mechanic not entirely sure what he was supposed to do next.
