BEst of Week: Lear vs Edgar

WHen Lear encountered Edgar in the forest, Edgar was disguised as poor Tom, and acted like a crazy beggar. In response, Lear showed Tom comfort and appeared to be the more sane and stable figure in the scene. However, in scenes with other characters (not in disguise) Lear seemed like a mad old man. What was the significance? TomEdgar showed the extreme of insanity, but he was not actually crazy, and in the scene with LEar, he showed foreshadowing of what Lear could become, but when Lear took him under his wing, it showed that he hadn't yet completely lost it, but there was still much more left for LEar to suffer.
