Billy told RadioTimes: "You can expect to see people going a little bit further for sure – people that you never expect to come out with things they've probably never done before. What they do do is just truly amazing. So yeah, you can expect the unexpected!"
Downes went on to further tease: "There's going to be a lot more surprises. There's always a dark horse, so to speak, and you can expect more of the same at an intense pace. The pace goes up now."
Are we about to witness an underdog story unfold?
Meanwhile, Foxy referenced "more pain and hardship" in store for the famous sixsome before echoing Downes' words: "They dig deep and who's left at the end I think [is surprising]."

"Now it's down to the wire. Now we're left with the real hardcore – the people who really want it in their heart. It's now down to how much their body and mind can take and that's the truth," added Billy.
"It's really down to them and you'll be shocked thinking, 'I never thought that person could do that!' In terms of people getting injured or worse of it, we're through that barrier. We're now down to: give all, to win all!"
Celebrity SAS: Who Dares Wins concludes on Channel 4 this Sunday (October 3).
