In Tuck Everlasting, what three things happen that seem to have no connection between the Tucks and the Fosters?
The three things that the question is asking about can be found in the story's opening prologue. It is there that readers are told that three things happened that appeared to have no connection to each other at all.
The first thing that happened was Mae Tuck began to head toward the town of Treegap. The narrator tells readers that this is something that she does every ten years. This event happened at dawn.
The second thing that happened was Winnie Foster decided that she would begin thinking about running away. This event happened at noon.
The third thing that happened was a stranger arrived at the Foster home looking for someone; however, he would not say who exactly he was looking for. This event happened at sunset.
The events are connected to each other because Mae is going to Treegap to meet her sons. Winnie runs away and meets the Tucks, and the stranger follows Winnie and the Tucks in order to learn their secret.
