When the 2 surviving HMs find out that it was the public who nominated them...
 

..and not Michael...will their behaviour change because they've realised that they're not popular with the public..will they also become 'actors'..?...

Frankly,I think it was way too early to have the public make the choice anyway.
They were only in the house barely 3 days when the public were asked to make the choices.

I didn't vote because I don't know enough yet as to the housemates to make a good decision as to who should be up for eviction.
Whereas for those 3 days and more, the housemates have lived together for 24 hours a day so can make a better more informed decision as to nominations.

This is going to turn into a sad series if the public really already think these are the worst 3 in there so need to go,especially now with vote to evict back.

the problem with bb has always been the people that are classed as entertaining are not nice people.
people don't want to watch people they don't like so they get voted out!
