So any ideas as to this bombshell on Friday?

Possibly that someone has to be booted out there and then. Someone maybe the chosen couple get to pick from their time in the bolt hole?

They'll probably say who is actually the first evicted - or maybe they'll do a carol and get to have a nom each and that person automatically faces the vote

It will probably be like the time Ron and Vicky were given the power to nominate one housemate who would automatically be up for the next eviction.

oh christ, that could mean the bolthole housemates being immune for for 2 evictions!

Probably as bombshellish as "we're back".

Who knows. Pick anything that's been done a million times and that'll be it.

What would be interesting (and thus it will never happen) is that whilst whoever is in the secret room, the public vote on who to evict/save from the rest of the house, (they could even have some task which the HMs think is just some random fun thing but actually results in certain HMs being up for eviction).

Then when whoever comes back into the house they tell the HMs who is going to be evicted as if its their choice as opposed to public choice. That might put the cat amongst the pigeons a bit.

I am sure that whatever it really is it won't be anything exciting in the slightest.
