Evan was standing in front of the corpse he just killed. Was it an infected? Or Giraffy? Or someone completely random. Suddenly he turned around and noticed you were walking away. He grabbed your shoulder and pinned you against a wall. He put his knife closer to your throat and stared at you with an insane look on his face. Why would he do such a thing? (I'm sorry @_TeaKettle if it's far from your canon AU :,) )
