Also to anyone wondering what the girl says at the end she says this:
"This child isn't mine. This child is from the darkness. I bore the humanity's curse. I can ask for mercy, which I won't get. My soul will be consumed and thrown up and then consumed again. Forever. Sick joke, but no one's laughing. My blood will stay. Death isn't the end. I'm in hell. This is hell."
