House Baelish (or: seriously, what is this guy up to)
The direction of the series has me worried for the life of Peter Baelish, the Littlefinger. When he was in King's Landing, sitting on the Small Council, being Master of Coin, and running his brothels, he had multiple schemes going at all times to make sure he could maneuver around the political climate of King's Landing. Season 2 saw Littlefinger traveling around the map, popping up in various places to put schemes into motion (which eventually paid off with Catelyn Stark setting Jaime Lannister free and the Lannister/Tyrell alliance that ended up saving King's Landing at the Battle of the Blackwater).
So it's puzzling that Baelish has nothing to do in Winterfell besides ham-fisted attempts to undermine Sansa and tell all the Stark children how much he loved their mother. When Brienne says that she would do anything in service of Catelyn's memory, it rings true. When Littlefinger says he would have done anything for Catelyn, all we can think is what Sansa thinks this episode when she hears about the Catspaw dagger: Littlefinger doesn't do anything unless he thinks it benefits him. Right now, the only justification for his actions seem to be lust, which...is small for Littlefinger. Maybe he really is in love. But the way he's coming across in the past few episodes feels more like a visual cue to the audience that Sansa might be having doubts about ruling, which is unnecessary as Sophie Turner's got the "out of my depth" look down.
