re: GoT Middle Ground Thread - SN 7 - NO LEAK DISCUSSION ALLOWED - Book discussion okay

Ok, some questions: Sam left Oldtown in a huff, transcribing old moldy scrolls... it is from these that Gilly read the "Rhaegar got an annulment and remarriage" bit.

I thought he just kinda left those, and went back to the forbidden area, to snatch up some locked books. In fact, I seem to remember him basically pushing the scrolls he was transcribing aside.
Did he take the scrolls he was working on when he left?

Did anyone still think the Archmaester was trying to point him in a certain direction, and did he leave before he got what the Maester wanted him to find? It seems quite a coincidence that Gilly was looking at scrolls that might have stated "Ned Stark took the child of this marriage North, and claimed it to be his own bastard son, fearing that the new King Robert would kill the baby if he knew it's true identity" in the next paragraph.

Also, for those clamoring for Cleganebowl- just what, exactly, is the Hound supposed to do with the Mountain? Nothing we've learned about the Night King's zombies seem to apply to him; different type of reanimation. I'd guess that you would have to basically destroy the entire body, since he's already "dead"; and that wouldn't be an easy thing to do when he's trying to kill you. I suspect a dragon could eat or burn him, but the Hound isn't able to do either of those
I just don't see what anything smaller than a dragon would do to break him.
adding this question= do we think the Mountain is "dead enough" that the Night King can do anything with him, or is he now safe, like Benjen is? The Children stopped Benjen's conversion and it left him basically like the Mountain; cold, black and pale, but no glowing blue eyes.

Is Brienne sworn to also protect Bran, or just the 2 Stark girls? I don't remember the conversation exactly, and this story seems to thrive on technicalities. And by extension, is Jon excluded, since he wasn't Cat's kid, or was it Ned Stark's kids? Just Cat's, right?
