Tyrion Lannister, not quite our universal moral compass but definitely a sort of ethical compass, has more than once indicated that out of all the players in Westeros Littlefinger makes him the most...nervous. Indeed, Petyr Baelish may appear an ancillary character, one arguably on par with the stealth spider Varys, but he may be the most dangerous character in the Game of Thrones series—and not just because he hands over women to Joffery for target practice.
In the penultimate scene of last night's episode (3.6 "The Climb"), Littlefinger delivers his most sinister speech to date—one that not only reveals his philosophy, but perhaps the guiding philosophy of The Game of Thrones:
"Chaoes isn't a pit. Chaos is a ladder. Many who try to climb it fail and never get to try again. The fall breaks them. And some are given a chance to clim, and they refuse. They cling to the realm, or the gods, or love. Illusions. Only the ladder is real. The climb is all there is."
We may think Littlefinger will soon be out-of-sight, out-of-mind as he heads off to the Eeryie to marry Jon Arryn's widow and Catelyn Stark's sister, Lady Lyssa Arryn, but my money is on him not being gone from "the game" for very long...especially since we all know he has designs on Sansa Stark....
