In the context that Deana said it in it was ridiculous of Lydia to take offence at it - but I don't think she was genuinely offended. Lydia is a clever girl and i think that she knows deana isn't liked and doesn't want to be associated with deana by the other housemates. This (as petty as it was) gave Lydia the chance to put up a barrier between her and deana and distance herself a little bit in front of every other housemate sat at the table. She is very clever I think!
