Out of the many deaths on Game of Thrones that fans found extremely satisfying, the killing of Lord Petyr Baelish, a.k.a. Littlefinger, at the hand (or, rather, dagger) of Arya Stark in season 7 was among the most memorable. While fans cheered to see the duplicitous social climber get his comeuppance, a recently resurfaced fan theory regarding the series' final season claims we might not have seen the last of Littlefinger.
The first occurs in the season 7 episode "Spoils of War," which proves Bran Stark is finally catching onto Littlefinger's ill intentions. Bran recites the "chaos is a ladder" line back to Petyr, a reference from his past. Many fans wondered then why Littlefinger wasn't suspicious enough to do anything. Fast forward to the next episode, "Eastwatch," where he is told by a young woman in a soft yet extremely creepy whisper, "Sorry, your time is up." To that, Littlefinger hands her what looks like an iron coin of the Faceless Men. While this confused many viewers, the fact that he was slain by Arya just two episodes later kind of halted our speculation there.
However, according to the Redditor, we shouldn't have believed Baelish could be killed off that easily. The theory argues that the person we saw die in "The Dragon and the Wolf," the season 7 finale, was actually one of the Faceless Men disguised as Littlefinger.
Given Littlefinger was completely shocked when it became obvious the Stark siblings were turning against him in the episode, MrSilenceT posits that this could mean it wasn't even Baelish at all. The writer points out the fact that whenever he was close to death previously in the series, Littlefinger knew what to do:
"Every single time, calculate[d] and impeccable control. As you would expect from a man that has been plotting for 30 years straight without a rest. Such a man will not be taken by surprise when the end comes. But a faceless man playing the last moments of this man would think he would be."
It's true. Littlefinger dropping to his knees so suddenly after he realized what was truly going on was unexpected. But why would a Faceless Man be willing to die for him? This is less clear, but Littlefinger has stated previously that his grandfather was from Braavos. There could easily be a lot more about his past and his family that viewers just don't know about.
While it's possible this fan theory is just that—a theory—the Redditor makes a convincing case for how this could happen. It is the final season of Game of Thrones after all; viewers should prepare for some wild twists when the series returns on April 14, 2019.
