a promise ;)

A man with a beard and dark hair, wearing a jacket, stands in a dimly lit room with stained glass windows, facing another man whose back is to the camera, then raises a long object; the scene cuts to the same man in a different location, holding a knife to another man's face, then to a close-up of his face with blood and a bandage, then to him looking down, and finally to him holding a man's head while speaking.
