These two (in the books) are more alike than you would think. Although Brienne doesn’t have Sansa’s traditional good looks, they are both very naive and innocent. In fact, one of the words that is used to describe Brienne frequently is “innocent”. Catelyn says so herself, telling her there is a “sweet innocence” about her. Moving on, both are very dreamy and think life is a fairytale, and both are awoken from their dreamlike mindset to a harsh reality. Sansa goes to King’s Landing, thinking it’s going to be like a fairytale, a paradise of sorts, and it turns into her worst nightmare. Joffrey kills her father and she is prisoner and used as a pawn for years. Brienne was the victim of a cruel joke, there was wager with some knights in Renly’s camp about who could get her maidenhead, so they all were courting her and complimenting her to see who would be the winner. Brienne shortly found out about the joke and was deeply hurt. Both are awakened to the real world and its cruelties. Also, both have an obsession with true knights, the kind in stories who are chivalrous and good, and full of valor. But both realize there are no true knights truly, Sansa learns that in King’s Landing and Brienne learned through her various encounters with them. Brienne though genuinely wants to become a true knight, and is constantly aspiring to do so. This is just my two cents on the connection between Sansa and Brienne.
Being straight is like being in gryffindor: all the main characters are always gryffindor, there’s tons of merch for gryffindor, and no one’s gonna give you shit for being in gryffindor.
Being gay is like being in slytherin: everyone has heard of it, but the merch is few and far between so you have to really want it. The only slytherin characters are secondary and morally gray. Some people think you are evil.
Being bisexual is like being in ravenclaw: there is no merch. there are no major ravenclaw characters. people definitely try to lump it in with either gryffindor or slytherin, and there are a few weird stereotypes.
