I thought it was meant in relation to the house design. There seems to be a few groupings of 3 going on in the design.
- 3 sinks in bathroom
-3 sunloungers grouped together in garden
-3 armchairs around the circle table with guns
-3 single beds right beside each other in one section of bedroom
Maybe there will be 3 seats in the viewing area above pool?
If the housemates drift into their own little groups of friends as usual then maybe there will be more than the usual 2 or 3 main groups in the house, but smaller groups of 3 people or so and they will each end up all having their favourite little spots to hang (and bitch
)?
