Mean Spirited Towards Henrietta Plout
Earlier in the series, when Henrietta was played by a different actress. there was rivalry between her and the Bradley sisters. When they changed actress, they made Henrietta less appealing, homely, and to be snickered at along with her mother.
Prior to the time, that the girls were able to glamour Henrietta up, they had done some mean things to her or used her to get back a boyfriend or get even with her mother. It was refreshing to see towards the end of the series to be-friend her and help her out.
