Catherine remains at Thrushcross Grange for five weeks. During her stay, Mrs. Linton works with her, transforming the wild girl into a young lady. When Catherine returns to Wuthering Heights, she is barely recognizable. Hindley, treating Heathcliff as a servant, allows Catherine's playmate to step forward to greet her when she arrives. Catherine kisses Heathcliff, but while doing so, she comments upon his dirty appearance and compares him unfavorably to Edgar. Heathcliff is hurt by the changes in his friend's appearance and attitude.
