Who's breaking the rules now?

On Saturday, Mikey was chatting to Luke about Belinda (and because Luke was involved, it was bound to be bitchy) - he said that if she kept him awake again with her snoring, she's "going"... once again a housemate makes their nomination intentions clear!
So on Sunday, Big Brother sent Mikey straight to jail. No passing go. No £200.
Will they ever learn?!?

Meanwhile, poor old Rachel heard some voices over the wall - other housemates would probably simply brush them off, but because the voices were chanting for somebody out (she couldn't make out who), she's now all worried...
