It is so obvious that the mind boggles people don't get it - she's been on a journey my ass! She blew up big time when she was up for eviction and then....... went all 'sweet' before eviction night - it's called damage limitation.
She bullied and kicked and moaned her way around the house when she was strong and backed up by her gang - then as the gang started to fall apart, she started walking away from fights (trying to be the 'mature' one) until she eventually flipped...
now she's just a changed, totally reformed person
