There have been times the evictee didn't get the normal Friday night goodbyes but got a shock by being called to the diary room at some other time and evicted from there.
As far as I recall, no -one has ever been up for eviction that wasn't first nominated by the HM's or alternatively the whole house was up together.
This twist is completely different as they neither know they are up nor were they nominated by the HM's.
