Readers of C. S. Lewis’ The Lion, The Witch, and the Wardrobe will remember the novel’s dramatic ending: Peter, Lucy, Edmund, and Susan, now all grown up and ruling as noble and just kings and queens of the land of Narnia, set out to hunt a mysterious stag; their hunt leads them into the woods, toward ‘the lamp post’–the one that had brought them to Narnia in the first place, and then suddenly, as Peter, Lucy, Edmund, and Susan find themselves back in ‘the wardrobe’ all too soon, they are back in England, back in the here and now, and barely an instant has passed. (Many Narnia years you see, only amount to a second or so of Earth time. Indeed, it is not clear at all that any time elapses while the children are in Narnia; the two timelines are disconnected.)
Of course, because only an instant has passed, the children are children again–they are not adults any more. They have shrunk, physically. But presumably they have shrunk psychically too; after all, back in Narnia, they were adults, and their growth into adults would have involved progression in the physical and psychological dimensions. Interestingly enough, the children remember their experiences in Narnia; which means they have memories of their growing up, their transformation into adults. This journey back to ‘the real world’ is likely to be far more disruptive, then, than C. S. Lewis lets on; Peter, Lucy, Edmund, and Susan, are, on their return to earth, facing possibly one of the most hallucinatory of all experiences: years and years have passed by, and then, one day all of a sudden, you find yourself a child again, but this is not any ordinary child, this is a child with memories of having been an adult once. So, even if this child does not have its physical child capacities any more–perhaps they pre-pubescents again–it still remains an open question whether this child remembers its adult responses in the emotional and psychological dimensions. Does the child now behave as an adult might? What is the effect on the Pevensies as they continue their lives, with these memories reminding them of what they once were? Note that had the children gone to Narnia, and spent say, a few months there, and then been shot back through the wardrobe to land up back in England in the same way as before, these questions would not have arisen. They arise only because Lewis insisted on giving the Pevensies a full-blown reign in Narnia, a long and prosperous one of fifteen years.
Lewis has thus created a tricky situation for the Pevensies. As they grow up here on Earth, they will slowly become adults but they will not be the adults they were in Narnia; after all, Earth is not Narnia: its lands and peoples are significantly different. The Pevensies will have different experiences, encounter different circumstances and react differently. Of course, since they carry around their memories of their psychological growth, they might use those as inputs into their development in this ‘new life’ but they will still certainly not be identical to their Narnia selves. They will have multiple personalities of a sort–perhaps akin to that of the immigrant, who remembers an older world, an older self, older ways of behaving and responding to the world’s offerings. Their friends and lovers and family might find their repeated invocations of their past irritating and bothersome at times, but also of singular interest; the Pevensies for their part, if they play their cards right, will ‘enjoy’ having lived two lives–once again, much like the wise immigrant does, who considers himself fortunate to have experienced ‘two worlds for the price of one’–even if such experiences do bring their own fair share of heartbreak. (The novels featuring the Pevensies themselves span nine years–from The Lion, The Witch, and the Wardrobe to The Last Battle.)
A budding writer could do worse than to write a novel that tracks the Pevensies’ developments as adults, back here on Earth, when they are done with the Narnia phase of lives, but with those Narnia memories animating their hybrid selves.
