Isabella Linton - Introduced as part of the Linton family, Isabella is only shown in relation to other characters. She views Heathcliff as a romantic hero, despite Catherine warning her against such a view, and becomes an unwitting participant in his plot for revenge against Edgar. Heathcliff marries her, but treats her abusively. Pregnant, she escapes to London and gives birth to a son, Linton. Because she, unlike Catherine, suffered such abuse from her husband and ultimately escaped from it, many critics—particularly feminist-theory critics—consider Isabella the true (conventional) "tragic-romantic" heroine of Wuthering Heights.
