This episode's title, "Wheel of Fire," is drawn from King Lear, Act 4, scene 7: "You do me wrong to take me out o' the grave: / Thou art a soul in bliss; but I am bound / Upon a wheel of fire, that mine own tears / Do scald like moulten lead." Toward the start of this episode there is a production of King Lear starring Arthur Leander (Gael García Bernal).
