EVERYONE KNOWS THE TRUTH ONLY STANNIS AND JON ARE OBLIVIOUS! In-depth Stannis/Davos backstory fic sounds amazing. ^^ I still think that Stannis only married Selyse because he could be sure that Robert wouldn't seduce her. Nothing else makes sense.
Sansa could bitchslap zombie!Selyse? No?

BB!Renly probably thought Davos was a really awesome pirate who saved them. Or something like that. But there's no way we can take Davos away from Stannis.
