Greg took out a antibacterial solution, iodine, cotton and placed them by his side. He poured the solution on Brandon's injury, Greg was starting to feel unease as he attended Brandon's injury, it was bloody and very sickening.  The wound didn't stop bleeding until Greg poured alcohol on it. Then came the most disgusting part. Greg had to pull that shrapnel from Brandon's side. Greg never did anything like this before, not once. Though he had some medical training. 

As Greg slowly pulled out the shrapnel, his stomach started to rumble from the blood and flesh. "Aaaah" Greg groaned softly. The shrapnel was out. Greg was about to throw up. When Horace came and knelt down by Brandon. Greg took in a deep breath in attempt to prevent himself from puking. "He's gonna be okay" looking at Horace he assured him. 

Greg applied the iodine around the wound and made sure to cover the whole injury. The wound must be stitched. Greg returned everything back to the mid-kit and took out the stitching tools. It will be a very unpleasant experience for Greg, but he had to do it. Before starting he searched the mid-kit in desperation to find a skin adhesive. It would make things much easier. But there was none. "God damn it" Greg sighed. 

He prepared the needle and everything. He then took a deep breath before starting to stitch the wound. Moments later he was done. The stitches weren't that of an expert hand, but they'll do the job. Greg was relieved, he sat down back and looked around. He needed a drink after that little "surgery" of his. Greg noticed his hands were bloody, Brandon's blood. Now he needed a hot bath and a drink.

Greg stood against his own will of comfort to check on Carter. As he stood he grabbed the mid-kit and headed to Carter, who laid against a wall. He sat beside Carter and asked him "You need any medical attention?".
