I have started writing a horror story that is also somewhat masked as a commentary on people who find themselves in abusive relationships. My first idea was to have the opening scene be the main character in the bathroom, bleeding into the sink, and tending to an open wound on her cheek after having been punched by her husband. How likely is this to happen? Or rather, how likely is it that she will even be in a state where she can deal with a wound like this after having been punched that hard? If the skin on her upper cheekbone were to tear open, would it be likely for bones to fracture or for her to be rendered unconscious? Is it more likely to start bleeding from your nose without losing consciousness? I would like to have the scene contain blood just for the sake of effect, but I don't want to be inaccurate, so if I just have to write that she is bruised then that is fine.
