[LaLaLand]

It could be something to do with that 'snug' glass thing in the garden which has been highly rumoured to be an elevator. The girls could be told to go in that and be taken up to a second floor while all other housemates are locked in B-Block or the Luxury Bedroom? Then possibly tomorrow one housemate could be told to go to the DR, this housemate will have the secret mission of keeping these 3 girls secret etc etc and eventually 2/3 will enter the main house. Basically a repeat of Makosi and her Secret Garden twist in BB6 but with -hopefully- significant differences.
