The fact that they believe they are C.S. Lewis makes this a really unique situation. Since I am familiar with C.S. Lewis I would ask the person which work of his they like best. I would then ask if there was anything in particular from C.S. Lewis that shows that he believed in reincarnation (the answer would obviously be no). I would then share how C.S. Lewis was a devout Christian most notable for his liar, lunatic, or Lord argument. I would ask if they, like C.S. Lewis, believe Jesus is Lord. If they did I would share with them how the two are mutually exclusive. You cannot believe in both reincarnation and resurrection.
