Adam, Ashleigh, Deana and Scott all face eviction this week in the semi-final.
And housemates are currently unaware that two of them are set to leave in the first double eviction of the series.
It's the first time Scott has faced eviction, and he's admitted to being nervous about going up for the public vote.
"They know I'm going," Scott said of Big Brother. "That's why I was given the task," he added, referring to yesterday's secret mission.
Sara tried to reassure: "110% I don't think you will go."
But a pessimistic Scott continued: "That's just my honest opinion, I will go. The public has never had a chance to get me out, this is their chance."
Fellow nominee Ashleigh told him: "Scott, don't be silly, this will probably be my week. I think this is my week, 100%."
"If it's a double we'll both go, I'd love to go out with you," Scott added.
