Charles also realized that the person in front of him had been taken out by Jimmy, and he had come to trust Jimmy's abilities. He immediately twisted his body toward the back door and moved to a position where he could see it.
The two men at the front door stopped hiding as well, turning on their flashlights and shining them into the room through the windows. Of course, they did so alternately, not standing directly in front of the windows themselves. After a few flashes, they turned off the flashlights. One of them took out a cell phone and started communicating in a low voice. It was just too bad they were outside, so Jimmy couldn't hear what was being said.
Soon, the call was ended, and he said something to the other person, then they got in touch with the people at the back door to meet up at the main entrance.
