Nick sat on the ground, with his pistol in hand and his free hand reaching for another mag. All he could get from the other side of the door was silence, which probably meant they didn't want him in. He lightly knocked on the door, quiet enough so that the others couldn't hear it. To his surprise, what came back was not the sound he expected. The people inside hadn't bothered to lock the door, which meant that they were, officially, cold hearted bastards. Well, not that that wasn't to be expected. From across the room, Juno yelled at Nick to move, to which he obliged.
[b]"Yes, [i]Captain[/i]"[/b] he replied, making sure to add a large amount of sarcasm to his mention of her rank. It was great teasing her about that. He stood, and shot the nearest person he saw to make sure the gun was working. Then he swivelled and shot straight at the door, the bullet breaking through it and hitting the ground by the two inside. 
[b]"I'll be back for you two later"[/b] he yelled at the door as he turned away and fired a couple more shots into the crowd, one hitting one of Juno's men and sending him sprawling to the floor. 

Nick found his way to a door; a locked door. It was pretty sturdy by the looks of things, and wasn't likely to give way if he tried breaking it down. He kicked it a couple of times, causing a loud banging sound to reverberate around the club. Then he drew the pistol and shot at the handle, causing it to break into pieces and scatter across the ground. The door swung open, allowing Nick access to the higher floors where the leader inevitably was. He kicked the door open slightly and made his way up the stairs, finding an office of some guy. He kicked the door in and aimed his pistol directly at the man, who sat with a pistol to his head whilst looking very solemn. He wasn't going to kill him, because torture was so much more fun. He fired off a set of shots, one aimed for his right leg, another the left and the final one the raised arm. As soon as they fired he dropped the gun and grabbed two different items; his knife, and a syringe he kept in his pocket. Holding them, he leapt at the guy with ALMOST full intent to kill. Except that he wasn't, despite the syringe being filled with poison. Who knew, maybe the guys was just like him; a freak of nature.
