I'm really surprised that he would want to backdoor Elena. He always says Elena is his type, maybe he's ticked off she is not returning his feelings. Honestly backdooring Elena is such a non move, but it's Josh so makes sense. Josh is also going to make Jessica, Elena, Mark and Matt have nots. He is not making Cody a have not to keep him away from Jessica at night (although Cody can sleep in there anyway), also Cody doesn't care about being on slop. They are putting Matt in there to keep an eye on them so they can't conspire at night, another reason why Cody will not be put on slop. Raven told Matt he has to stay up until he's sure they are all asleep because he has to make sure they aren't talking. By the way, do you all know Raven got a free from slop pass or whatever it's called for the season.
Also, Mark will now be on slop for 4 weeks. I think that is why he looks so out of it. They really should have a rule someone can only be on slop for a certain amount of weeks.
