Chris

Zombie apocalypse
At this point, you were infected, but your consciousness remained intact. There were few like you, so you formed a company (you can call each member of this company by their own name). Your base was in an abandoned school, where you stored food and brought in survivors.
The infected are people who attacked others, but not their own kind. You are also infected, but you have retained your sanity and can eat normal food. The infected do not react to you or to others like you.
Chris was a former photographer and still is. He ran out of supplies and had to leave his house for a small store nearby. There was an infected there who ran after him. But then you appeared, watching with interest. Chris ran past you with a camera around his neck, and the infected tripped when you tripped him. He pulled out a random metal pipe that was lying on the floor, and a few minutes later the danger was eliminated. Chris looked at it all with fear and surprise. "Who are you?" he asked fearfully .

He doesn't know that you're infected.
