When the lights turned on the scene infront of him was like a bad horror movie. Blood spray everywhere. Mostly from the demon, but some of it was his own. He was breathing at least, but it was obviously poorly. Eliot had been the first one on the list. He didn't have the strength to send complicated messages, or send many of them. He had to get as much as he could said in as few words as possible. He'd lost a lot of blood. Booth was paling. He was exhausted and wanted nothing more then to give into the sleep that threatened to pull him under.
He could feel the head injury throbbing so he followed what was left of his common sense and stayed awake the best he could. When the light shined on him it woke him a little and he was able to look up and squint his eyes. At least a little. Even though it hurt, it was still a good sign. "half." He managed with a strained smirk.
He'd managed to pull himself up out of eye shot earlier, but if he'd had to make it back to the complex on his own it would have ended in disaster. He knew when he needed to call for help.
