The cherry orchard is mine now, mine! [Roars with laughter] My God, my God, the cherry orchard’s mine! Tell me I’m drunk, or mad, or dreaming. … [Stamps his feet] Don’t laugh at me! If my father and grandfather rose from their graves and looked at the whole affair, and saw how their Ermolai, their beaten and uneducated Ermolai, who used to run barefoot in the winter, how that very Ermolai has bought an estate, which is the most beautiful thing in the world! I’ve bought the estate where my grandfather and my father were slaves, where they weren’t even allowed into the kitchen. (3.151)
Talk about a dramatic moment. Suddenly, Lopakhin’s true character is seen as he clearly sees himself as different than Lobov and her children. This isn’t their friend or Varya’s potential future husband, this is a man who bears his ancestral woes and climb the social ladder to make his dead father proud. No wonder why he doesn’t marry Varya, he sees himself as different from them. They were the family would even “allow [his grandfather and father] into the kitchen.” And here, he finally buys that land legally. In a way, that moment of ugly pride for being able to win within the system must have been the same way Shylock felt when he thought he won in court against a Christian. Karma is finally served and it feels amazing.
