It's always the quiet ones. I was just thinking, how did the babysitter die? The doors were intact, and it was only the babysitter we found in there.
Whatever happened to the babysitter, looks like it happened inside. There are what look like little footprints through the blood.
Maybe clem didn't want to eat her vegetables, did whatever, then ran and hid in the treehouse. Yes, I'm bored, with nothing better to do.
