"I can understand that," Brennan replied, his mind drifting to the few he had seen in his life. "I've heard more stories about the Wakers than any others. There's just something about them that haunts people. Some of even the most efficient trainees used to come back with nightmares about them. Killing the other infected was different, easier, because they were like wild animals. But killing something that seemed like it was begging for help, that really disturbed a lot of them."
He wasn't sure what he would do if he ever came in contact with a Waker on his own. The trained part of him new that he would know well enough to just put the thing out of its misery, but there was some unsettlingly human about them, about their reactions, and the part of his soul still seeking catharsis for what he had become would certainly suffer with its death, and that doesn't include the side of him that wants to do some more research into that kind of infected.
Brennan sighed a little as he looked out the window, looking at everything and nothing in particular. Once he had started his patrols, he watched everything like a hawk, absorbing all the details he could. He was surprised that his head hasn't burst from all the information he's crammed into it as of late.
"I remember you said something about that," he said, almost absently as he thought about that conversation. "It would be almost impossible to test though, but I also have no idea how that's done." Whatever slight preparation Brennan had undergone giving his mother the idea that he could still change his mind and become a doctor was old now, and those kinds of theories were still in their infancy when he had been going to school. All the 'forward thinkers' had their hypotheses, but none of them had any proof.
The lone corpse was still as stationary as it had been, and nothing else was moving, no sign of any other infected, and Brennan had a feeling that the one left on the pavement was the weakest of its horde, left behind. The infected had no concept of loyalty, so it wasn't a shocking thought that they must have just abandoned that one, not that it would even know it had been abandoned, that concept lost it them as well.
Picking up his bag, he tucked the paperwork underneath the small armory he carried around. Any information the fallen infected could have would be useless by morning, it's body ruined by the environment or carried away.
"Now might be the only chance to get any useful information." He stated, turning to her. "You want to bring anything in particular before we go?"
