Kafka's Trail? Whats that? Alright, Im trying to think of a few things, I dont know if these will make the essay that much longer:
1. Daughters revolting against their father.
2. Using the King's Madness against him for his daughters gain
3. People willing to kill for power
4. Two stories going on at one time (Daughters against Lear, and Albany/Lear against his daughters).
5. Betrayal?
6. Deviding possessions among siblings
7. Fighting over ownership of land
8. IDK! Heh
This of course in a mimetic sence.
