Fitness trainer and aspiring actor Carlin has remained the fan favourite throughout the series, so he is expected to be in the final with Timm - if the gaffe proves to be true.
Following the on-air slip, Sportsbet revealed that it had slashed Timm’s odds of winning the show, which meant his outsider odds at $16 were slashed to a mere $2.50.
According to Sportsbet's revised odds, Carlin has drifted to $1.55 on the back of the on-air gaffe.
While no names were mentioned, the slip-up suggests Ryan will be leaving the show sooner rather than later, and he now has a $6.00 shot of finding love.
Sportsbet’s Rich Hummerston said while it appears Osher may have slipped up, the network has previously hinted at a winner to throw people off.
“We’ve seen these tactics before from channel 10, so we could still be in for a surprise tonight. For the punters’ sake, hopefully it’s not Carlin getting the a** tonight,’’ he said.
Viewers will watch Angie send home either Ryan, Timm or Carlin in Wednesday night's episode ahead of the finale on Thursday.
