Can't believe nobody's asked what happened to the dog.
[spoiler]We knew there was at least 1 other person out there. It's not a far stretch to imagine there was some kind of rival community, or poachers, or rogue troublemakers.
So the dog runs off into the woods. NBD, dogs run off all the time and find their way back.
Ok, but not only is the dog returned in a bloody mess, but it's also still technically breathing, so it had to be a fresh wound. Oh and yeah, THE DOOR WAS OPEN.
- Who opened the door?
- Was it Paul? Was he sick and went into some kind of sick sleep trance?
- Was it Will? Did he steal the key and do something to the dog?
- Was it Andrew? Was he a demon child or something crazy?
