I think they should be silent, no boos/cheers/nothing, don't give the housemates ANY hints... any thoughts?

I think they should chant GINA GINA GINA throughout the entire show to be honest.

I think they should be made to be quiet when Emma talks to the house, I loved the eerie silence waiting for the name to be read out. Then they can cheer/boo all they want when the housemate walks through the doors. Then they have to be quiet for the interview with the evictee.
