Sam will want Callum.
Sophie will want Twins.
How will they decide between them?

I think this is right.

It may in the end be a matter of practicalities - 4 in the safe house may not be very comfortable.

I think Sam wll go for who Sophie wants.
I do have to say and I am liekly a tiny minority as to it but I don't like this twist.
Sam and Sphie will genuinely be thinking they are doing a housemate a favour and a really good turn,it is going to devastate them when they are told what is really happening.
Even on BB, I would be devastated to be involved in this if I was in there.

This should have in my view had the publics input. I am all for secrets and lies as such but this is a bit beyond that as to the position Sophie and Sam are in now.
