A nommed housemate can save themselves or add £25k to the prize fund.

A true 'are you here for the experience or the money?' dilemma

I was thinking something similar. But did Emma said only a 20K add to the fund? If so and it was only a confidence thing of letting yourself stay up but adding money to the pot that was only a few grand would you bother? I'd hope for something more interesting but it's hard to say this year.

I don't think it will involve anyone being saved as if it did there would be nothing to carry on the money is power theme all week.

My guess is a series of one to one challenges where the winner can either pocket £5k or add it to the prize fund.

Emma also said the words double cross twice so there has to be an element of some amount of money being up for the taking

No brainer.

Buying Helen's immunity will be the main event!

Ooo I like that idea- but how would you react if someone did that would you love them for it or loathe them

Got to be.

I think we would say if Helen did sell her immunity for cash that would be wise.

If she gave it up to save someone from eviction or nomination for cash to stand in herself, That might save her?

Or if they offered to add a huge amount to the final prize money if she gave up her immunity that could make the others pressure her or bargain with her to give her a percentage of the win.

The available options are many and quite interesting,
