Nick stopped, they'd been walking round and down dark corridors for nearly 15 minutes and found nothing but a trail of doorways into small rooms. "I definitely y think this is the basement. Look, stairs!" he hissed, pointing in front.

"Wait at the bottom." He said, moving carefully up them. Catherine sat at the bottom while Sara and Grissom carefully lowered Greg down. Warrick stood with his back to the group but kept glancing over his shoulder as he watched Nick disappear round the corner of the stairs.

"I think he's coming round!" Sara whispered, leaning forward, watching Greg's eyes flutter slightly.

"Greg?" Grissom asked softly, getting a grunted reply. "Think you can stand?" getting another grunt he watched as Greg opened his eyes and blinked. His didn't quite focus, but at least he was awake.

"Nick?" Catherine hissed, standing up and taking a few steps up to the top. Warrick turned and followed her up, over taking her and stopping so the top was just in sight.

"Nick?" Warrick asked, crouched ready to fight.

"Yeah!" Nick suddenly popped round the corner, causing both Catherine and Warrick to jump. "Whoa! Easy!" he said, raising his hands up in defence as Catherine lowered the knife.

"Christ Nick, I could have hurt you." She gasped, holding her ribs.

"Sorry, think I've found the right way, come on up." He disappeared again as Warrick went down to help Grissom. The pair of them brought Greg carefully up the stairs; before he went back down to help a pained Catherine with the help of Sara.

"There's a single corridor with some stairs going up, the front door should be around there somewhere." Nick whispered as Greg turned to look at him. Grissom had left him against he wall as he watched Catherine's progress up the stairs from the top. Nick stood with his back to the entrance to the corridor watching Grissom. It was that that caused their mistake.

"Nick!" Greg cried out, springing forward as the figure swung forward for the Texan. Grissom spun round and charged across to the two men on the floor and toppling man above them. Pulling a fist back he connected with the figure and sent them both over. A struggle ensued, consisting of the two men rolling down the corridor, a knife slashing this way and that and ending with Warrick pulling the other man off Grissom and throwing him into the wall, knocking him out cold. Warrick stood over Carl, the last hench man of Mrs Marlow before looking back at the mess behind him. He went to the Grissom first and helped him stand up. He had a nasty cut on his cheek, but looked okay. Together they approached Greg and Nick. Nick was just crawling out from under Greg and was carefully rolling him over.

"Nick, you okay?" Warrick asked, kneeling down beside him.

"Yeah." He held one hand over the top of his arm while checking Greg over.

"Lets take a look at that." Said Catherine as she came up behind them with Sara. Together they moved Nick off to one side.

"Here." Warrick whipped his top off and then his vest. He tore his vest apart and handed a few strips over to Catherine and Sara, before putting his top back on and the checking Greg over. Glancing at Grissom he handed a small square of material over for his cheek. Looking back at Greg he spotted a long gash across his back, pulling back the shirt he involuntarily flinched. The old scars from the lab explosion were printed all over the younger mans back. The cut wasn't deep, but it was long, and in an awkward position so it would be hard to dress. The fact that he had never see the scars on the younger mans back shocked him, but thinking back he remembered that when ever they were all getting changed, Greg would always go towards the corner, facing them.

"Is it that bad?" Greg asked groggily as he pulled his shirt back down with a hiss and pulled himself up to his knees, trying his best not to go with the swaying room. "Shit." He muttered, emptying the contents of his stomach on to the floor.

"Concussion." Grissom said as Catherine came over and taped a square of sheet over Grissom's cheek. He frowned at the tape and then frowned at her.

"Helps to keep the bottom of the trousers from dragging." She laughed.

"What about Nick?"

"The knife went in deep, but he should be okay. It could have been worse if Greg hadn't tackled them." She explained as Warrick stood over Greg and rubbed his back until the younger man was giving dry heaves. Greg fell back against the wall, taking deep breaths and letting them out with a hiss.

"Thanks man." Nick said, standing up with some material around his upper arm. A small red spot was appearing but was at least slowing the stem. Nick gave his good arm out and helped Greg up and with the help of Warrick the two held him straight, stopping him from swaying.

"Lets try down there." Sara suggested, grabbing Greg's elbow and taking some weight as Warrick took lead with Grissom. Sara and Greg stumbled after them with Catherine and Nick limping at the back. They carefully stepped over Carl and made there way to the door at the end in front of the stairs.

Holding his breath Warrick grabbed the door handle and swung the door open.
