It's been a long time since Shylock left, and now he's back at his stepmother's house. He's a little lonely, since it's so empty. He can't figure out why his stepmother didn't tell him that he was coming home, and he feels sorry for her. He takes a bath, which reminds him of the time he masturbated. He imagines that his stepmother is having sex with his father, and that she's stroking his back, which makes him feel "electrocuted" .
