<P> Charles Wallace is the youngest Murry child, being five years old . He is very smart and is the most extraordinary and the most vulnerable of the novel's human characters, and the youngest to journey to Camazotz . Charles Wallace did not talk at all until he was nearly four years old, at which time he began to speak in complete sentences . Now five years old, Charles Wallace speaks only to his family, but can empathically or telepathically "read" certain people's thoughts and feelings, and above that has an extraordinary vocabulary . A biological "sport," he is intellectually curious, loving, and unfazed by extraordinary people and events . He was the first to meet the Mesdames W and brought Meg to see them . Initially able to block IT out of his mind, he opens his mind to the Man with Red Eyes and thus falls under IT's control . </P> <P> Calvin is the third oldest of Paddy and Branwen O'Keefe's eleven children, a tall, thin, red - haired 14 - year - old high school junior who is not the best in math but has to study to play on the school basketball team, and is one of the popular boys in high school . His mother is a very cranky, tired woman with too many children . Neglected by his own family, Calvin enters the lives of the Murry family, starting in Chapter Two . He also loves Meg Murry . He shows some signs of being able to communicate telepathically, the same power Charles Wallace seems to have, a technique referred to in later books as kything . He also feels as if he has been hiding his true self all his life, and likes the Murry family much more than his own, which is characterized by abuse and dysfunctional dynamics . </P> <P> Mrs Whatsit, Mrs Who, and Mrs Which are immortal beings who can travel across large stretches of time and space by dematerializing and rematerializing . They are capable of shapeshifting, but spend most of their time on Earth as elderly women . All three are billions of years old and were once stars that had sacrificed themselves as a nova or supernova to destroy parts of the Black Thing . </P> <P> Mrs Whatsit is first described as a very old woman wrapped in layers of clothes with a jacket and first appears in chapter one . Charles Wallace finds her in a' haunted house' in the woods, where she has been living with her two friends, Mrs Who and Mrs Which . Mrs Whatsit is the youngest of the Mmes . W (despite being 2,379,152,497 years, 8 months, and 3 days old), and the best of the three at interacting with the children . </P>
