Linda and Jim are similar age in the house, and Linda doesn't really have anyone to really relate to in there - except Jim ,and if Jim's not really that interested in talking to Linda, or listening to her woes adjusting to the house, perhaps that's why she's turning on Jim and being snappy and trying to show him up infront of the other housemates.
She openly said she didn't like Jim when she first went into the house... then denied she'd said anything bad about him when she realised he WAS going into the BB House
- He doesn't like her, probably finds her dull and boring, so in retaliation, she's badmouthing him to the others - she doesn't like him, but even so, it was blatant she was being bitchy and trying to influence others opinion on him, ringleading busy body !!!
