Big Brother Twist: [Spoiler] Has Left the Show

Well, that didn’t take long. Not hours after the first primetime installment of Big Brother 13 aired, one of the cast members left the building — and under somewhat mysterious circumstances.

What’s more, the AWOL houseguest is not one of the unproven newbies, but one half of a returning “dynamic duo.” This person’s name: “Evel Dick” Donato.

“Due to a personal matter, Big Brother houseguest Dick Donato had to leave the game unexpectedly on Thursday,” reads a statement from CBS. “His departure will be addressed on the episode to be broadcast on Wednesday, July 13.”

Donato reportedly went missing shortly after the season premiere. As seen in Showtime’s BB: After Dark feed, he apparently entered the Diary Room and never came out, leaving his partner/estranged daughter Daniele confused, EW.com reports.

Donato’s exit is sure to have a ripple effect, given that he was the winner of Season 8, and promised to keep things “interesting.”

CBS’ go-to summertime crowd-pleaser, Big Brother returned to strong numbers on Thursday, winning the night in both total viewers (7.7 million, up 3 percent from last year’s opener) and in the demo (with a 2.7 rating, up 13 percent).
