One of the most common things I read about in this fandom is how you shouldn’t put Sansa and Dany against each other because they’re going to be such great friends, just wait and see!! The two queens of Westeros!!! They’re so alike!!!
And I’m sorry, but no.
On the surface both of the characters are very similar. In fact, if I said “she’s been forced into marriage, raped, beaten, and lost almost every single important person to her but came out stronger at the end” you wouldn’t know who I was talking about, because that description does apply to both characters.
Both Sansa and Dany have been forced into marriage(s) against their will; they’ve both been raped by their husbands as well as put into situations where the threat of being raped was very present; they’ve both been beaten and tormented and emotionally manipulated. They’ve both lost so many important friends and family members; experienced more loss than anyone should ever go through.
But what makes them different, why they would never get along; why they would never co-rule or be friends, is how they changed as a result of those experiences and their motivations for continuing on.
