This just made me think. Can you imagine how few female characters there would be if there was no coming back from slapping men. Even as a kid i never really got that. The energy should be the same for anyone being slapped just because someone is beyond using their words.
And context does matter. Like the context of slapping someone because they are possessed in a sense makes sense because it's unnatural and so maybe an unnatural response will bring someone back to their senses. And a slap is a lot nicer than lighting a match which most are taught to do when confronted with the occult.
