<P> The 2010 film adaptation shows Susan in a few brief scenes newly added for the film . She is seen at the beginning of the film writing a letter to Edmund and Lucy . Later in the film, Lucy steals the page with the beauty spell from Coriakin's book and at night recites the spell . Looking in the cabin's full - length mirror, she sees herself, grown - up and beautiful, in effect becoming Susan . The mirror swings aside to reveal a society lawn party back in Lucy's world, and she steps through into the party to be joined by both Peter and Edmund, both of whom address her as "Susan". When she tries to remind them about Narnia, to her growing horror, neither of them seem to know what she's talking about or to know anything about a younger sister named Lucy . Lucy then wakes up in the ship's cabin and is confronted by Aslan about what she has done . Aslan tells her not to judge herself by the standards of others, and reminds her that it was only through her actions that her siblings became aware of Narnia in the first place . </P> <P> In The Horse and His Boy, set during the Pevensie siblings' reign in Narnia, Susan plays a minor part . She is described as a gentle lady with black hair falling to her feet . Shasta thinks her the most beautiful woman he has ever seen . Susan has become a motherly or sisterly figure to Prince Corin of Archenland following the death of his mother . She is asked to make a diplomatic marriage to the Calormene Prince Rabadash . She finds him gallant at tournaments in Narnia, but tyrannical and repellant on his home ground . The prince intends to hold her in Tashbaan by force; but her guarded rejection and subsequent escape from Calormen on The Splendor Hyaline with her brother Edmund and their entourage lead the Prince to rash action . He seeks the secret approval of his father, the Tisroc, for his plan to attack Archenland as a means of capturing Susan, and in the hope of subsequently conquering Narnia . </P> <P> In The Last Battle, Susan is conspicuous by her absence . Peter says that she is "no longer a friend of Narnia", and (in Jill Pole's words) "she's interested in nothing now - a-days except nylons and lipstick and invitations ." Similarly, Eustace Scrubb quotes her as saying, "What wonderful memories you have! Fancy you still thinking about all those funny games we used to play when we were children," and Polly Plummer adds, "She wasted all her school time wanting to be the age she is now, and she'll waste all the rest of her life trying to stay that age . Her whole idea is to race on to the silliest time of one's life as quick as she can and then stop there as long as she can ." Thus, Susan does not enter the real Narnia with the others at the end of the series . It is left ambiguous whether Susan's absence is permanent, especially since Lewis stated elsewhere that: </P> <P> The books don't tell us what happened to Susan . She is left alive in this world at the end, having by then turned into a rather silly, conceited young woman . But there's plenty of time for her to mend and perhaps she will get to Aslan's country in the end...in her own way . </P>
