I believe the more likely purpose for the loft is that it’s related to the unspecified twist that’s supposed to be revealed at the end of Big Brother Season 23’s live move-in premiere.
Perhaps a Houseguest could get the option to live in the loft with some special perks but risks alienation from the house being stuck outside?
Could any Houseguest pull that off and stay in the game?
I’m excited about that idea not only because it’d be so different from past seasons, but also because of how risky it would be to isolate oneself from the house no matter the reward.
