just watched it again 2nhgt ,those pair are a bit annoying but everything they say is a possible outcome,id say thats the way the producers want it keeping people guessing etc
,as for 8 series i dont see it happening however the more i watch it the less it tells us whats going on and only widens the possibilitys which i find very annoying but i keep comin back for more,
its a very original idea but one cant help feeling its locking into the whole reality TV revoloution we have going on tis past few years.
I dont think even the writers/producers know where its going yet.
