Silly idea for a hypothetical TF2 show

A halloween episode where Merasmus traps the crew in a horror book where the goal to escape is to not to get themselves or any other character in the story they find themselves in die in the multiple stories. Trial and error pursuits and someone and the people in the story end up surviving and they're all free and celebrating, but leaving that one who save them all traumatized because he's was in a place of a father role and just lost his kid/s because they weren't real.
