At Chris and Claire's response, Jack nodded, taking mental stock of the surroundings from what he had seen while hunting. The brush got fairly thick to the west, at least as far as he could see, which would mean that they would be difficult to detect initially. However, shrubbery didn't protect well against bullets. If a firefight broke out, both sides would likely be fairly exposed. To Jack's knowledge the cabin was the only actual structure in the camp, save perhaps for small bathrooms dotted throughout. As Jack cleaned the blood off of his skin as best he could and donned his shirt, he snuffed out his own fire, careful not to do it too fast and create too much smoke, and glanced over at Chris and his nearly empty handgun. After a moment's deliberation he removed his own handgun from the holster and, holding it butt-end out, offered it to Chris along with the spare ammunition, a box containing thirty rounds, he had on him.
"Use mine, I have my Remington. And," he noted that Claire fought with throwing knives - a weapon wholly unfamiliar to him - instead of a gun. "If I can make a suggestion, let Claire carry your gun. It's nearly empty, but they don't have to know that. And if things get hairy, use what you know how to use. The gun's for appearances; they may not be intimidated by knives, but they'll notice a gun." 

He checked his shotgun and made sure it was loaded, before grabbing a few more rounds just to be safe. Again he went inside to hide his possessions under the sink, returning with a pensive look on his face. He did it often back in D.C., work everything out in his head, a game-plan, and found that his skills as a quick thinker also came in handy after the world turned to shit.
"Chris, I think you should stay in cover while Claire and I approach them. It'd be better not to let them know our true numbers in case they are hostile, and with the gun having a longer range than her knives, it'll mean more precise coverage. What do you think?" He asked, before turning to Claire as well. "What do you [i]both[/i] think?"
