Why do I get the feeling that they've got it all wrong? But if they are right, and this thing is some sort of psychic criminal that's getting better and better at affecting them, well that's trouble! Already it has overcome their solution of not going out without all the others and not sleeping together by coming to them as Eliot while they were awake. It's damn scary to think of what it might do next!

A perfect solution for the divers: kill themselves and get it over with before he uses them to spread. It might end up happening anyway!
