So our last question is: What does Lear’s new-found ability to “see” in act V have to do with the subplot involving Gloucester’s blindness? As we’ve noticed, the subplot involving Gloucester and his sons runs parallel to the main plot involving Lear and his daughters. Before Gloucester can “see” the truth about his two sons, he must be physically blinded. How does the Gloucester plot frame the conclusion of the Lear plot? What is it that Shakespeare (who says “nothing” about what the dying Lear “sees”) is trying to show us through the parallel to Gloucester’s story?
