Im not sure really, like I doubt many of them knew about the extension unless they were fans of the show.

I doubt they know if there relatives were in the house, i'm sure most it was standard questions that everyone gets asked, like have you had past relationships etc.

And producers could just look through their FB to find out the names of the people ex's probably.

I'm sure someone has mentioned it in the house, there's probably loads of theories spinning round like most years. I'm sure they will have discussed the possibilities of more HM's entering etc.
