Honestly, I'm not going to be surprised if the entire hour is centred around the party.
It makes sense. "Late Night Feast". Big Brother supplied them with alcohol and set the whole thing up for this show. It will start with all the HM's discussing "adult" conversations like marriage equality and refugees, as prompted by Big Brother, and then they're given music to dance to and are subsequently lead to the spa shenanigans.
Rather than allow all the "mature" BB content to flow and form naturally, the whole thing will be contrived and forced.
I know this is really negative of me, but it seems true enough.
What makes it worse is that I've just realised, "Late Night Feast", the party... what's the bet that Big Brother will make them do this once a week for as long as this show airs? So rather than getting a combination of mature content from throughout the series in the house, instead the show's main focus will be a weekly uplate party from the house like this one.
I reckon this same thing is gonna happen every week, like the "family dinner".
I could be wrong but that's just what I'm gathering from the show right now before the first episode airs.
