I don't think we can say either way (there's no spoiler so only the people who were there actually know).
It seems extremely likely based on past form that Fleur and Molly have the least support. But Will can only escape the dance-off if he gets more votes than either Hamza or Helen: a much bigger ask.
Since none of Will, Hamza or Helen have ever been in the dance-off we don't know which of them has the most support - and even if we knew how much support they normally have, we don't know how much extra underdog support Will might have got from being bottom of the leaderboard.
I'd have thought that Helen and Hamza were hoovering up the votes with Will a strong third, which would put him in the DO. But that's only a guess.
