Laz could only see stars as he opened his eyes, at least, he was going to call those flashes of lights in his vision stars since he had no idea what else to call them. His head felt like he had been hit by a truck and his body felt like it had been hit by a train. What was the difference? If his head had been hit by the train, it probably wouldn't be attached right now.
When Laz regained his focus, he noticed that Ichpochtli was gone. Laz couldn't see any trace of her which meant she was probably ok. Had he seen a body, he would have been worried. As far as Laz was concerned, if he survived, she survived.
Laz slowly made his way away from the crater that was left in the ground. Obviously something had been fired at them, but Laz was kind of confused as to why it was only one whatever. He had survived and so had Ichpochtli which meant that they had failed to kill them.
