Perhaps Jeff thinks that Ep. 5 is nothing out of the ordinary aside from the tribal swap and decided to give a tease for episode 6. Don't forget that Jeff will be leaving for the Philippines to film season 25 in a bit so there might not be any more touts from him for the rest of the season.I have tried not to mention this but our old friend Jim Early (aka missyae) has been sending tweets to people, who want to stop watching because of Colton, reassuring them that Colton will be voted out in episode 6. His tweets could very well be attention seeking BS. I remember that he had me believing on twitter that Ashley/Natalie were going to blindside Rob in S22 and we all saw how that worked out.
Contrarily, at Sucks, Polonium has posted a spoiler that Monica and Christina are voted out in the next 2 episodes as well as some additional information.
It will be interesting to see how it all plays out.
