Topdog/Underdog

The theatricals mirrors in Topdog/Underdog seemed unrelated at the beginning of the play, but by the end, it appears that both of them are united by control. The card game is a trick that is all in the hands of the dealer. Lincoln is the master of this illusion, so much so that he even makes Booth think that he learned Lincoln's moves. This relates to President Lincoln in real life. He ruled the country, so he had a lot of power in his hands. His power was then taken by Booth, when he was killed, both in the play and in reality.
