Norman trusts therapist Dr. Gregg Edwards, who tells him about his multiple personality disorder, enough to allow questioning his over-protective Norma-personality, and going in hypnosis about his traumatic youth with a (wife-)abusive lush father. Sheriff Alex, who dealt with Rebecca and their greedy secret, is puzzled by Norma's virulent hostility when handyman Chick Hogan delivers the stained glass to them, and she comes clean that he blackmailed her to help track down Caleb, whom she refuses to expose to revenge despite having raped her fathering Dylan, yet lacked the courage to shoot Chick. Meanwhile Norma contacted Caleb in Costa Rica, which inspires him to contact neglected son Dylan, who starts his new life with Emma, getting Norman's blessing without telling that also means leaving Portland for Seattle.
