Change in Catherine after she returned from trushcross

When she returned home she had been transformed into a young lady with that role's attending restrictions: she could no longer kiss Ellen without worrying about getting flour on her dress. She hurt Heathcliff's feelings by comparing his darkness and dirtiness to Edgar and Isabella's fair complexions and clean clothes. The boy had become more and more neglected in her absence, and was cruelly put in his place by Hindley and especially by Cathy's new polish. Cathy's affection for Heathcliff had not really changed, but he did not know this and ran out, refusing to come in for supper.
