His whole character was lame this season. Surely "one of the most dangerous men in Westeros" and one of the most intelligent characters of the entire show would have noped the fuck out of Winterfell after Bran hit him with that "Chaos is a ladder" line. But noooo, let's have him standing around in dark corners for the rest of the season. I still love the show, but it's a shame that they dumbed down Littlefinger and Varys and focused more on the popular characters instead. The thrill that any big character could die anytime, like in the first seasons, has completely vanished.
