Time is also important to this story. Wilbur is constantly under pressure in terms of time. From the time of his birth, it is established that by December he will be part of a meal. The passing of time is indicated through the changing of the seasons throughout the book, creating flow for the readers and reminding them that time, for Wilbur, is running out.
Fern is also a vital character in this story, and probably the most dynamic. In the beginning of the story, Fern is very stubborn and innocent. She fought for Wilbur's life and was content spending her time at the Zuckerman farm. As the story progressed however, Fern grew, as all children do, and lost interest in spending time with her animal friends and grew more interested in Henry Fuss.
Finally, Charlotte is the most stable and static character in the story. She is clever and caring from the beginning, knowing full well that her own time was limited. Charlotte is the character that not only solves the problem of saving Wilbur, but also teaches Wilbur and the readers important lessons in love and devotion. While static, the character of Charlotte is most definitely not flat. The character is deep and well developed.
One of the most flat, static characters is Templeton. His character remains primarily the same throughout the story and plays on the literary stereotypes typically given to rats. While not as developed as some of the other characters, Templeton is vital to the story in that he was responsible for locating words for Charlotte to spell.
Birth and death are also central to the story. In fact, the entire story is centered around the idea of saving Wilbur from impending death. The story starts with Wilbur's birth, and right from the beginning the threat of death is predominant in the story. Even after being saved by Fern, the threat of death drives the plot of the story as Charlotte tries to save Wilbur from slaughter. While Wilbur's life is saved, birth and death are revisited at the end of the story through Charlotte's passing and through the birth of her babies.
