The £5000 was originally part of the total prize for the winner of £150,000 but was removed at the beginning of the twist as punishment for people talking. She had the opportunity to add it back to the fund, or take it for herself. It would only really be "her money to give" if the housemates had successfully raised the prize back up to the original £150,000, and the £5000 was an additional extra that could raise the fund to higher than this. I totally don't blame her, most people - including me - would've done the same, but t definitely does make her look a bit silly after the fuss she's made all week about any money being taken away from what the winner deserves.
