Talk:The Chronicles of Narnia: Prince Caspian/@comment-25909626-20150102222021/@comment-25041621-20150103194002

In "Voyage of the Dawn Treader", Aslan tells Lucy, "in your world, I am called a different name. You must learn to know me by it." He says that Peter and Susan have learned what they could from Narnia, suggesting that NArnia was a sort of opprtunity for special children to experience the world in a more inspiring adventurous way, but when they got older and more mature, it was time for them to face reality and find their way in the world they were meant to live.

But it seems it was still a matter of choice to some extent, as by The Last Battle, Susan has apparently lost her interest in Narnia, though Peter would have definitely stayed in Narnia had he had a choice.

P.S. About what I wrote above, that is the reason I am not so happy that everyone dies prematurely in The Last Battle, because it suggests that it is really not possible to live with God in our world and that escaping to Narnia is the way to handle things.
