So... did he manage to get that arm cut off and preserve it, or was someone else able to find it and he took it?
Either way, he is a creepy fuck and she should have just cut his head off instead of disfiguring.
Since neither Arthur's or her first love's faces weren't revealed, I'm inclined to believe Arthur killing him might've been metaphorical. Meaning that they are the same person and him revealing his true colors "killed him" for her.
There's a typo here. Was it meant to be "i'll find you a body" or "i'll find your body"? Both have have very different implications, has he fallen in love with a bat snake monster and is looking for a new body for her or was the woman he loves turned into the bat snake monster and he's trying to turn her back? Pretty interesting either way
