Waiting for Godot
Who is he?
In the Play and video ahead, Lucky is show to be very articulate and questions God and religion. Lucky states, "Given the existence as uttered forth in the public works of Puncher and Wattmann of a personal God quaquaquaqua with white beard quaquaquaqua outside time without extension who from the heights of divine apathia divine athambia divine aphasia loves us dearly with some exceptions for reasons unknown but time will tell and suffers like the divine Miranda with those who for reasons unknown but time will tell are plunged in torment plunged in fire whose fire flames if that continues and who can doubt it will fire the firmament that is to say blast hell to heaven so blue".
Basically Lucky is talking about God and the great divine which mean Jesus or different religious meanings. His speech also questions the human existence and what are humans doing on Earth. Then he starts to discuss heaven and hell, describing hell as fire and flames while Heaven is blue. Those who suffer or sin will go to hell while those who don't shall go to Heaven. Even though Lucky was kept trapped and beside Pozzo at all times, he had enough time to formulate a theory so he is able to grab ahold of some knowledge and the Bible.
Another trait that Lucky has is he is intellectual or smart. When Pozzo asked him to think, Lucky could have said any random thought. But he decided to focus on an important topic like God and questioning all of human existence. He sometimes got off track on what he was talking about, but he would always make his way back to the original topic of his speech. Which means Lucky is aware enough of his surroundings and mental state to know where he has gotten off at and go back.
In the beginning, when we first met Lucky we only saw him as an obedient and abused slave but now the farther we get in depth to actually know something's about all of the main characters we see that he is more well developed and smarter than we thought.
