You're in a dark alleyway and being surrounded by few zombies in there. You felt lost and hopeless as you sat there in silence until another zombie came toward you. He seems a bit different than others?..

He just looked at you with curious manner but doesn't attack you. Suddenly, a zombie tries to attack you but he immediately stop them and growls at them as if he doesn't want you to get hurt

He doesn't speak in human languages though
