Cathy's nature, a combination of both her parents, is key to revising the past. Her wildness and willfulness lead her to Wuthering Heights and the problems and pitfalls related therein. Her constant loyalty, good nature, and perseverance, however, eventually restore order and love to the farmhouse, thwarting Heathcliff's plans for revenge.
Just as Catherine's presence dominates the first half of the text, Cathy's rules the second. Edgar tries to keep her from Wuthering Heights (and from Heathcliff), but her attraction to a man and her independent nature — characteristics that mirror her mother — once again make Edgar's appeals ineffective.
