Edmure Tully & the Red Wedding
Robb and Edmure were at odds frequently. After Tywin's nephews were murdered, Edmure wanted to bury them quietly so Tywin didn't exact revenge and not announce their deaths until after the war. Robb didn't want to lie. Edmure also wants Lord Karstark kept alive, but Robb refuses and executes him.
When negotiating Walder Frey's reconciliation with Robb Stark, Edmure is pressured to marry a Frey girl in Robb's place, since Robb fell in love. Edmure's uncle Brynden threatens him if he doesn't agree to marry Roslin Frey. Edmure wants to at least pick a daughter of his own, but Catelyn scolds him for that. He eventually reluctantly agrees to the plan. At the wedding, he realizes that Roslin is beautiful and his happy about that. He leaves with Roslin and it is only after he leaves that the Red Wedding happens. That's what influenced the creation of a number of memes about Tully, including the one in this photo. (Facebook)
