Nothing can redeem Marnie. She's just as mardy and as much of a pest as the loudmouth men.
Not a great fan of Saira who, for someone with her life experiences, seems very naive to me (there really are some people you just can't help, Saira, so you should stop trying), but I really don't want her to go this week. It should be Bear or Lewis (preferably both of them) just to rattle the cage. If Saira goes the loudmouths will really become impossible and I think the aggression and violence will escalate. CBB really won't be worth watching if the majority of the HMs are so intimidated they don't participate!
