As we saw in Game of Thrones season 7 finale that the Stark sisters along with their brother proved to be the doom for Lord Peter Baelish. Sansa Stark is the Lady of her ancestral home Winterfell and its leader as well. Since Jon Snow is not around as he has gone to Kingslanding with Daenerys Targaryen.
In Game of Thrones season 8 episode 1, we’ll get to see Jon Snow arriving at Winterfell along with his Queen Daenerys Targaryen. This is not going to sit well with Sansa Stark. It is quite obvious that Jon Snow is in love with his Queen Daenerys Targaryen and they have been sleeping together the whole journey. Whatever Sansa Stark is going to suggest Jon Snow,
Jon will only be seen doing whatever his Queen Daenerys Targaryen will command him. This not sits well with Sansa Stark who is overwhelmed with the power she has got all of a sudden and thinks that she is right and Queen Daenerys Targaryen is wrong. She thinks that Jon Snow’s relationship with her is clouding his judgment, but in reality, there is nothing like that. Nonetheless, this is the first brick of hatred for Sansa Stark against Daenerys Targaryen.
Actually, coming into her home and ordering everyone like it is her business won’t sit well with anyone and especially with Sansa Stark. Sansa also thinks that Daenerys Targaryen is very power hungry and just wants to sit on the iron throne, so it is clear that her every move will focus on her sitting on the iron throne.
This surely is not a time for them to decide who is right or wrong which is exactly why this is a rivalry that might show its true colors after the White Walkers have been defeated if they are defeated at all.
Sansa Stark has been through hell since she left Winterfell and Daenerys Targaryen has also been through a hell of her own. They both share a pretty similar origin, but surely Daenerys Targaryen is way more powerful than Sansa as she has thousands of soldiers and also two humongous dragons at her disposal.
She will lead the charge against the White Walkers and compared to that Sansa Stark is the Lady of Winterfell and nothing else. So, why should Jon Snow even listen to her? Jokes apart let us hope that this doesn’t turn out to be a rivalry; otherwise, Jon Snow will have a very hard time picking sides again.
