"I don't know you, but I'm not leaving you behind." He said, standing beside her, his duals out. As he shot at the zombies, he ran out of ammo, and pulled out his combat knife. With a press of a button on the bottom, they separated into two separate knives. He came back to her, and took off his jacket, throwing it to the side to reveal a belt full of grenades, rigged to explode at the pull of a string.
"Even if we were to run, there would be no way to escape this many." He said, and with a grim smile, pushed her into the cave. With that, he ripped the belt off, pulled the cord, and threw it into the surrounding horde of zombies. There was a huge explosion, and the building collapsed, as well as the entrance to the cave, which now allowed no entrance nor exit through that passage.
