In addition, the revelation of Kate's story provides definite proof that the Warden is seeking Kate's long lost treasure under the ground. It seems very likely that the Warden, with her red hair and freckles, is a descendent of Trout and Linda Walker who tried to torture Kate into revealing where the buried treasure was. The Warden has inherited not only the physical characteristics of red hair and freckles from her ancestors, but also their cruel personalities. The fact that Zero's real name is Hector Zeroni reveals another relation: Zero is a descendent of Madame Zeroni, the gypsy who may have put a curse on Stanley's great-great-grandfather. Although neither Stanley nor Hector is aware of the connection that exists between their families, the reader can put together the pieces and form almost the entire puzzle of Stanley's history. Once Stanley realizes that a mountain in the distance looks like a big thumb, it is evident (at least to the reader who has the benefit of an omniscient narration) that Camp Green Lake is very close to the site where Kate Barlow robbed Stanley's great-grandfather.
The way that the author mixes the past and present in the story reinforces the idea that the stories are parallel in many ways. Not only is Stanley digging on the same ground where his great-grandfather and Kate Barlow once walked, but he is digging with the relative of his great-great-grandfather's friend Madame Zeroni. The situations and characteristics of the people in one era are similar in many ways to the situations and characteristics of the people in another era. Just as Stanley's family curse has followed his family for generations, so personal traits and problems are passed down with successive generations. While Zero and Stanley are becoming friends and helping each other out, they are also threatening X-Ray's system of control. The boys are jealous that Zero digs part of Stanley's hole each day but the issue that really upsets them, especially X- Ray, is that Zero and Stanley no longer care what the other boys think of them.
