Thats what the spoiler sites have been saying forever so I wasn't surprised. It was way too graphic for me. I wish they wouldn't have showed it all. It was so gruesome I couldn't be upset about the deaths. I was too grossed out.
The spoiler sites knew this months and months ago. They called it. They always call it. They are always 100% right. They analyze who is filming on what day and who shows up, who does not. I also think they must have people on the inside.
