- Alternative Character Interpretation: Susan no longer believes in Narnia and wasn't on the train that killed the Pevensies, and is later blamed on Ambition Is Evil. As the majority of the book takes place in Narnia while the other Pevensies are dying, no possibility is given for a later Heel–Face Turn back to believing from Susan, potentially as a result of finding solace after the death of her siblings. Also, besides Ambition Is Evil, no reason is given why Susan wasn't with the Pevensies, when she could have been trying to get them out earlier and paid more attention to what was happening in the moment before returning to Narnia.
- Esoteric Happy Ending: A fairly well-known one. Everyone died and went to Heaven, er, Narnia. But not Susan, because since she no longer believed in Narnia, she didn't join them on the journey where they all died. C.S. Lewis stated in a letter that she could get to Narnia "in her own time." Apparently this was actually a Sequel Hook.
- Ho Yay: There are many yay-inducing moments between Tirian and Jewel the Unicorn, but this one takes the cake:
"Kiss me, Jewel," he said. "For certainly this is our last night on earth. And if ever I offended against you in any matter great or small, forgive me now.""Dear King," said the Unicorn, "I could almost wish you had, so that I might forgive it. Farewell. We have known great joys together. If Aslan gave me my choice I would choose no other life than the life I have had and no other death than the one we go to."
- Nightmare Fuel : The descriptions of Tash. If you've heard Patrick Stewart's audiobook recording, the character voice Stewart uses for Tash's words gives the monster a whole new dimension of terrifying.
