..even if he wasn't encouraging it, he could say more to Helen about her behaviour like Mark did with the Ashleigh thing because he's someone who she may listen to more than anyone else but he doesn't seem to even try..but then I don't blame him in a way either because he's probably aware what her reaction would be and the housemates in general must just think the 'to your face' thing is not worth it with Helen, with her screeching/insults etc...and they now she's safe and no going anytime soon so the 'mean girl' has to be 'appeased' rather than evicted which can't happen...it's a sham Helen couldn't look at herself with any of these criticism and feel she may have some flaws but no, it's always the other person who are being mean or false or whatever..
..no self awareness whatsoever/zero/zilch...
