It wasn't really in Markus's nature to question what happened to other infected around him. He went about his business, and they went about theirs. Whatever fate came to them wasn't his problem, but even he felt unease at this situation. The drastically dwindled down numbers of infected, and the rise of non-infected around him had changed seemingly over night, and now he was sure he was the last infected in the city.
That didn't really settle right in his befuddled mind, but he lacked the ability to really sit and question his situation, or understand it fully beyond there were more things that would and could kill him now than not.
Not that life had always been so easy with the other infected either, but at least he knew what to expect from them. With humans? Not so much. He knew them as food and as something to be wary of when he couldn't get distance on them, but past that he couldn't judge them. They did things that confused, startled, and bemused him constantly.
Speaking of humans and food.
The evening brought breezes with it that cooled down the temperature of the city over time, which in turn brought more people out in flocks to enjoy the rest of the day, and night, without the oppressive heat to push them back in doors. From his vantage point on top of a building, he could see them starting to scurry about below him going here and there with little care, but he knew to be cautious around them. Not to snag one from a group, but to wait for a straggler to duck through the alley and pick him off once he was out of the safety of numbers. It didn't take too long either, Markus was lucky that day, and soon enough one was doing just what he predicted them to do.
A well timed, precise shot of his tongue found itself wrapping securely around the neck of the man, and soon enough he was starting to haul him up, up, and away from the ground. His stomach gurgled its excitement over the promise of a meal.
