What Happens over Time?

An interesting observation I made, is that Pozzo and Luck could be analogous to Vladimir. Vladimir seems to be the one always in charge telling Estragon what to do. While it is not to the same level as Pozzo and lucky, there are some similar characteristics. In addition, Pozzo mentions that in the past things used to be different between Him and Lucky. I think it could be possible that Pozzo and Lucky could be the result of what will be come of Vladimir and Estragon if they stay too long in this continuous cyclical state of simply passing time; doing nothing, but coming day after day to wait for Godot simply as a way of giving meaning to there life. The means are an end to themselves so to speak. One point to argue this, is that in the second act when Vladimir suggests that they "play" Pozzo and Lucky, Vladimir seems to mimic the personality of Pozzo. There is irony here however because while Vladimir says he is going to play Lucky, he ends up giving the commands to Estagon in a similar fashion to how Pozzo commands lucky. The exchange on page 1396 illustrates this: E. What am I todo? V. Curse me! E. Naughty! V. Stronger! E. Concoccus! Spirochete! V. Tell me to think. E. What? V. Say Think Pig! E. Think, Pig! Here we see that Vladimir, though trying to be Lucky ends up giving direct commands that Estragon obeys in they way Lucky obeys Pozzo. Further on when Estragon says "i'm going," Vladimir responds by giving anther command "dance, hog!" which is similar to Pozzo's command on page 1375 where he says "Do you hear hog?...Dance, Misery!". Another point is that Estrogon wants to leave saying they would be better off alone (he repeats this continually throughtout the enire play), Vladimir keeps him around just as Pozzo keeps Lucky around even though he thinks he should be rid of him. On page 1370 Pozzo says "I do [want to get rid of him] but instead of drive him away as I might have done..."There is not a direct comparison for Estagon is the one who wants to be rid of Vladimir where pozzo is the one wanting to be rid of Lucky. Still I think there is still some resemblance in the two pairs. The implication of this comparisson could mean that either Pozzo and Lucky are in fact Vladimir and Estragon just in a differnt time, or that Pozzo and luck were once had a similar relationship to that of Vladimir and Estragon and that over time they eventual became what they are now in the play. If it is the latter (which I think) then over time Vladimir and Estragon will eventually become like Pozzo in Lucky. Questions: Do Lucky and Pozzo represent the relationship of Vladimir and Estragon in any way, and do you think V. and E could end up like Pozzo and Lucky? In the play, the characters are flat and have no development, yet the have a deep history where it is implied that they were once different and developed into what they are now. Does this mean that they will never change again, or are there any implications that they could develop further if the play were to continue on?
