Bill decides to hypnotize Wanda the next day, causing her to recall her abusive childhood: As a teenager, Wanda was brutally raped by the Bigfoot, an event her religious fanatic father, Emmet, witnessed in horror, convinced the beast was a demon. Emmet unsuccessfully attempted to induce an abortion by forcing Wanda to drink poison. Wanda eventually gave birth to the mutant half-human child, but Emmet killed it moments after its birth. In retaliation, Wanda burned her father alive in his barn, staging it to look like a suicide.
