What to take away from our interview with Allison Grodner: (listen to full interview below)

Twist is dubbed “Double Trouble” features dynamic duos from the past
Notorious twosomes, power couples, and pairs from the past are possibly coming back
The number of duos has NOT been confirmed and will be revealed on premiere night
TWO twists going on which are part of the same theme
Game will be played quite differently off the bat
The returning houseguests HAVE been chosen and HAVE been sequestered
The viewers are NOT voting on CBS.com, rather just voicing their opinions
Allison specifically mentioned Dan/Memphis , Danielle/Jason, and Marcellas/Amy
The room we haven’t seen so far is the Have/Have Not room
The cage around the spiral staircase does not lock and is just part of the design
The conflicting HOH room pictures was simply a design change and does not involve a twist
