It's true... unfortunately these two patients... have developed a unique kind of tourettes syndrome during their time in the house... they are suffering from Big Brother syndrome of course, but unlike other housemates they are struggling to restrain the symptoms from showing.
We believe the reason for this may be that they are both middle aged, and thus have a more aged and therefore less healthy brain than the younger housemates. We are expecting Jo to start showing signs of Big Brother syndrome soon as well.
