This is such a shallow view of Sansa. She knows that she (nor Jon) would never be safe, and always on the run, if Ramsey and Cercei were still looking for them. She wants safety & peace for herself, and now that she knows that her family is alive, she wants the same for them.
Sansa is more political and does what she needs to, to get shyt done...like a true Queen. Had it not been for her putting a battery in Jon's back, the Starks would've never reunited and Jon would've rode off into the sunset until the WW killed everybody. At least now people are aligning with one another to fight back (against the WW). Thank you Sansa!
She LIED to Jon about saving Rickon. Manipulating him into going to Winterfell under false pretense:
She LIED to Jon about having reinforcements, forcing him to go into battle undermanned. He even asked her point blank period what else should he do and she was like “” knowing DAMN well she had the Knights Of The Vale at her disposal
She argued with Jon PUBLICLY when he was making decisions as King of The North, undermining his authority.
Sansa makes decisions that benefit her true. And she should be commended for smartning up in that regard. But she doesn’t make QUEENLY decisions nor does she make decisions that would entice or inspire anyone to follow her lead. If she had pulled the shyt during the Battle Of The b*stards with ANYONE besides Jon they would murdered her the moment they saw her face again.
There is not one person on the show who should thank Sansa for anything.
