I think the only one for me (other than the not-confirmed but still obvious ones like Sandor on the Quiet Isle) is R+L=J, which is probably the same for a lot of people. I know I refer to it as fact at this point and have a very hard time taking anyone seriously who doesn't believe in it. Snobby but true.
I have some that I'm pretty sure of but not 100% (such as the idea that Dany either isn't AA or if she is, it's not a benevolent entity, or that Jeyne Westerling was switched).
Anyone else have any?
