After hearing Catherine mock Isabella Linton, her placid and naïve sister-in-law, for her being in love with him, Heathcliff uses this knowledge to his advantage, saying, “…thank you for telling me your sister-in-law 's secret: I swear I 'll make the most of it…” (11). Moreover, Heathcliff “makes the most of it” by devising a plan to beguile Isabella using her naïveté to fool her into believing he reciprocates her feelings for him although he despises her describing her as “that mawkish, waxen face” (105). Catherine’s outburst enables him to see a route to vengeance: he plans to marry Isabella both for her fortune and to spite Catherine and Edgar, who would never approve of Heathcliff as his sister’s husband. Nonetheless, while Heathcliff believes that this marriage will bring him happiness by thwarting Catherine and Edgar, and therefore having vengeance both he and Isabella end up miserable. Once marrying her, Heathcliff drops all pretense of love, treating her to a life of solitude and desolation, as Isabella laments, “[Heathcliff] promis[ed] that I should be Edgar 's proxy in suffering….
