Robb-"Wait so Bran, Rickon, and Arya aren't really dead? And Sansa's marriage was never consummated, her husband's on the run, and now she's escaped King's Landing?!? Wow that changes EVERYTHING...Maybe I should have wrote a different will."
Ned is probably biting his knuckles hoping for Sansa to get away from Petyr and head North and sad to see what's happening to Arya. He also wishes Cat could die more permanently, join him, and learn about Bran, Rickon, and Arya being alive-while finally having the Talk with her about Jon...At least he's reunited now with Rickard, Brandon, and Lyanna.
In the meantime, I imagine Tywin's punishment in the afterlife is watching the way his legacy crumbles, under Cersei while a bunch of Reynes and Tarbecks laugh in his face. I imagine he also has gotten an earful about those 'vile rumors' about Cersei and Jaime being true.
Let's hope Hoster is reading somewhere by a river, and doesn't have to see trash like Emmon Frey in his home.
In King Robert's heaven, he's probably on a eternal hunt/tourney day, with lusty wenches and plenty of booze.
