S3·E9 Master Class

Dexter joins John for a writing class, where another student entrances John -- until she writes a cruel character study of him. Meanwhile, Dexter's bizarre piece of fiction is popular with the class, and John forgets a favor he promised Mahalia -- who finds herself one of three women who shows up at a rage management seminar harboring resentment towards John. Catherine is upset because she ended her relationship with John; Carly is angry that he rejected her; and Mahalia is mad because he sometimes acts like her divorced husband.
