I have been wondering about her for, I dunno, about 3 seasons. I believe I have come to the conclusion that she is not going to sit on the Iron Throne.
One of the reasons that I have thought this recently, is that everyone is always saying, "she is not her father" or "she is not like her father, the Mad King". After hearing this so many times from various characters, I am wondering who they are trying to convince. Me (or whoever they are speaking to in the scene); or, themselves.
I have been seriously worried about Sansa since Daenerys' arrival. Sansa does not seem to be willing to "take the knee" to her; and, we know what happened to the Tarleys when they refused.
Sansa has taken the knee because Jon has.
