What is the rewind twist is...
 

They rewind to launch night and Adjoa gets evicted instead

..my thoughts are that there will be some type of rewind/reset twist of Simon's eviction, I'm not sure what but maybe they will all have to choose boxes again or another housemate makes the choices for them ..and there will be the option to have Simon back in and maybe another one be evicted..possibly a vote where the public make the final choice..?..

I didn't like Simon. But I do like your thinking of the timebomb twist. ❤
