YMMV / The Silver Chair

  • Applicability:
    • The Lady of the Green Kirtle uses genuine atheist arguments — Aslan is merely suggested in the mind by her cat as is the Sun by her lamp, the upper world is just a pacifying fantasy, etc. — to try and persuade the heroes that there is no Aslan (God) and there is no Narnia (Heaven). She could also be considered a Satanic Archetype.
  • Ensemble Darkhorse: Camilla Power's portrayal of Jill in the BBC adaptation makes her the favourite out of the various child actors who starred in the series.
  • Epileptic Trees/Fanfic Fuel: What exactly the Lady of the Green Kirtle is. At first she was said to be another witch along the lines of the White Witch. Then we found out in The Magician's Nephew that the White Witch was the only survivor of a destroyed universe, so the Lady of Green Kirtle couldn't have come from there. So who is she and where did she come from? Word of God says that she is the source of the green mist added in the film version of The Voyage of the Dawn Treader, which was meant to foreshadow her role in the next story.
  • Fan Nickname: The Lady of the Green Kirtle is often called the Green Lady and the Emerald Witch, despite neither appearing in the book's text.
  • Fanon: Some fans seem to think that the Lady of the Green Kirtle is actually Jadis the White Witch reborn. This mostly comes from a mistake in a manual (not written by Lewis himself) that describes Jadis as being in this book. Likewise Barbara Kellerman played both Jadis and the Green Lady in the BBC adaptations - but this is ignoring that several other actors also doubled up to play different roles across the adaptations (Kellerman also played the hag in Prince Caspian). It probably doesn't help that some characters theorize that the Lady of the Green Kirtle is similar to Jadis.
  • Fridge Brilliance: At the beginning of the story, Caspian is going to find Aslan and ask him what to do about his successor, given that his son and heir has been missing for years. When Jill meets Aslan for the first time, he tells he has been calling her and Eustace since before they called to him, and he then gives her the mission of finding Prince Rilian. Aslan was planning the answer before Caspian had even asked the question!note 
    • The Lady of the Green Kirtle's clothing, and later her appearance as the serpent, was described as "green as poison." This always seemed like an odd simile... until one remembers that arsenic was often used in the dyeing of (green) garments and wallpaper during Victorian times.
  • Hilarious in Hindsight: This story has a few aspects reminiscent of Urban Legends you may have heard on The Internet. First, the notion of a shapeshifting reptilian invader, lurking within an Elaborate Underground Base and subtly acquiring power through governmental infiltration and mind control, is eerily similar to Conspiracy Theories propounded by the likes of David Icke. Second, Puddleglum's climactic faith-affirming Author Filibuster, directed at an apparent Hollywood Atheist, rings of chain messages about good Christian students trouncing smug secular professors in arguments (though it should be noted that Lewis pulls it off a lot better than the authors of those copypastas do, seeing how he was such a talented wordsmith in general).
  • Values Resonance: The fact that the teachers allow such bullying to happen at the school is treated as a bad thing in the text. Despite School Bullying Is Harmless enduring for decades after this was written, this is quite telling.
    • Values Dissonance: However, Lewis also seems to have problems with secular education and with non-sex segregated schools.
  • What An Idiot: On hearing the story of Rilian's mother's death from Glimfeather, Jill is perceptive enough to realize that the beautiful woman and the deadly snake are one and the same. Later on the trip, when they come across the Lady of the GREEN Kirtle riding her horse in the middle of nowhere, Jill remains totally unsuspicious.
