Completely Unexpected but Possible Events

I didn’t even need to look over my shoulder to know it was there. To see it’s gray torn off skin, to see its guts coming out of it, to see it’s inhuman form walk tensely, making a slow step every couple of seconds. It hasn’t smelt me, probably because of the ice that has been stored up inside it’s nostrils. I haven’t heard it’s moans so it probably can’t see either. I thank God for this and turn around to confirm my guesses. It was a man, probably in its 30s when it was bit.
I could kill him right now, but he probably will decay completely in a couple of months, now that winter has ended and spring is starting. As I decide to kill him now, I hear the moans, dozens of them, coming to the camp. Oh shit. Where is Kenneth? Roman? Dimitri?
As I suddenly realize that my brothers and boyfriend are in danger, I don’t hesitate to take out my katana, and slice the zombie in front of me in half. I kept walking on the direction of the moans. I stopped in front of the forest that was downhill, where we usually hunt. Thinking about that, I started to run into it, completely alert for any scream that may come or moan that is supposed to be killed.
Then a scream came, to my right. Adrenaline pumped through my veins, and I was sure that if I saw one of those things, I could kill them with my bare hands. As I entered the forest in less than a second, I saw three of them that were going in the direction of the screaming man, one already at its feet dead. He sure is strong. But he has been bit.
