Alex saw an infected come out the alley and unsheathe his katana and stabbed the infected trough it's head. Then he turned around and looked the girl with the badly injured man and another guy with a gun pointing it at them. He saw that the man was bitten and he knew what that meant cause he saw his friend turn to an infected just cause of a scratch from those things. Alex quickly said,
" You have to kill him quickly before he turns, kill him while he is still human, you don't want that man to die a spawn of Satan do you, quickly save his soul as human not a monster!"
