Actually the real dumbest character of the season is probably Littlefinger, simply because he should have high tailed it out of Winterfell the moment Bran said "chaos is a ladder" because that should have been the telltale giveaway that the jig was up.
Did you miss the first couple episodes of the season? At the start of the season she wants Jon to take over the homes of the people who betrayed the Starks instead of forgiving children for the sins of their fathers and was also super focused on Cersei and her toothless threats from down south. Jon basically spent the first two episodes of the season talking some goddamn sense into her. The stuff Sansa wanted to do would have driven Winterfell into battles it couldn't afford to be in.
Leaving after he heard chaos is ladder is pretty hilarious, and those nice moments when the viewer knows so much more than the character and wonders why they don't act like it. LF sent Sansa to Ramsay, him abandoning her would have ended his plan of uniting the Vale and the North to go against Cersei during her weakest moment (which is when he would have struck). I also find it hilarious that LF is just supposed to know that a weirdo on a wheelchair quoting him once somehow tells him that he is a tree wizard that can see anything in the present or past.
Obviously...
She
should be focused on Cersei? Cersei is a crazy bitch and you know if Dragonlady didn't fly to Dragonstone until s8, they would be an instant target. Sansa doesn't know what allegiance Dany has, who she likes, and who she might go for. Pretending Cersei doesn't exist is dumb as fuck, even with the long night coming from the true North. I also agree with Sansa, that those kids shouldn't keep every single thing their parents had when they betrayed the Starks. There should be
some repercussions. Not go Robb Stark and off their heads, but they should lose something for their family's betrayal. Them being completely absolved is kinda stupid, which fits in line with almost every major decision Jon has lol.. Just like his plan to run south and hope the Boltons wouldn't go after them, it's naive to think the same with Cersei.
Again what battles would she have driven them into other than Cersei? And without knowing the wildcard dragon user, they should have been prepared. She didn't fully understand the dead like every other character in the entire series that hasn't seen them. All you're doing is playing Bran Stark by seeing everything and then wondering why x character acts like .. they haven't seen and know every character in the series like the manhattan cripple.
I don't think Sansa was playing LF simply because throughout the series Sansa hasn't been portrayed as a particularly intelligent character capable of scheming to that level.
Since season 4:
- calmed down her aunt from potentially killing her by lying to her.. until she got caught making out with LF
- manipulated the Vale high lords to save LF's life
- manipulated Ramsay into giving her info about Jon snu being lord commander
- kept pushing the bastard/family line which played a part in him killing his father
- convinced (and manipulated) Jon to force his hand and fight to get Winterfell, also telling him to ensure the Wildlings fight for him for it
- LF whose life she saved then helped her out (for his benefits)
- has LF murdered
I legit have to question if some of yall are even watching this show when I read shit like this. No, she's not Varys or LF or at their level. But there is a clear upwards trajectory to her raising through political maneuvering. That's why if she didn't see LF manipulating and manhattan crip literally did everything for her, it would be character assassination. If she used him to reference and double check her work, then it's ok.
