Uhm, here you go.

I narrowed by eyes, what could a brotherhood be doing here, it didn't add up .
"I don't understand, who are you and what are you doing in a small town like this?" it was night-time now, most of the brotherhood were asleep (or at least not moving) around a huge camp fire, that sat out in a nearby field next to the town hall.
"We are the Brotherhood, we have already told you this, what else is there to know?" said a rather hostile voice, he had the same southern American accent like Michael, but he wasn't nearly as friendly.
"I get that my dear, but who are the brotherhood?" I pressed further, the man sighed.
"We are men who have lost everything; our homes, our friends, our families. But we have not lost our humanity, and so we have all given our lives up to help others in these dark days, we hope that someday we can finish this madness." he explained and then spat into the fire sending sparks everywhere, causing Ruki to grumble and pencil role away from where she had passed out a few hours earlier next to the fire.
"How in the hell did a princess like her survive in this world." he asked me slowly, I chuckled.
"Never judge a book by its cover, you just wait till you see her in a fight." I smiled fondly at Ruki as though I was a proud mother, The man suddenly jerked to the side and ran off towards the town hall, and for some reason I still haven't worked out to this day, I followed him. When he got to the hall he ran straight to the planks, that had been protecting the building, and he stared between a crack between and he swore, I did as he did and saw that there was a single lone zombie bumping into the building.
"I have always thought that they traveled in herds, if there is one, then another one should be nearby." I mumbled to him.
"Not this one, it is either so stupid that it has lost it's own kind, or it is so smart enough that it worked out that we were in here." he explained swearing again.
"Or .. he could feel the heat from the fire." I replied, he turned towards me sharply.
"what do you mean heat?" he asked slowly, wonder filled his voice.
"Well I have had this idea about how they are able to hunt us." I explained quietly.
"Do go on."
"They are dead, so naturally all of their senses should be cut off, yet somehow the creatures still work. The way they bump into things, this one right here doesn't seem like he has a fucking clue what is in front of him, suggests they are blind … and smell-"
"-They sure do." he butted in, I snorted at his lame joke.
"I was going to say, that I haven't ruled that theory out yet, but I think it is certain that they can hear to some extent, I am sure you have experienced this at some point. But the heat theory, I came up with this at the school at the school after a shower, the showers were freezing cold and almost turned you to ice, I stepped out of the shower and outside stood a zombie, I seemed to be completely invisible to it, since then I have had the idea that perhaps they like the heat, like any cold blooded organism. I haven't really thought much about it since then, and now well, my theory seems pretty proven."
"We could use a brain like yours over here in the brotherhood, you'd get us out of some pretty sticky situations." he chuckled and shook his head, outside several more Zombies appeared outside.
"I guess it's time to test your fighting skills now." He passed me a blunt object and ran out side. The blunt object he passed me was a walking stick .. oh well I guess if you are going to disrespect the dead, you ought to do it with style.

I know in the original story they didn't say anything about heat, but I figured it would be more scary this way, because with sound they could just not make any noise, but with heat, there is not a lot you can do ... and well you know.
