9. Robb Marrying Talisa
On the surface, Robb and Talisa make for a great love story. The young, energetic King in the North, commander of the army of the North meets a noblewoman from the Free City of Volantis, serving as a nurse to a wounded Lannister. Robb assists her. The two strike up a conversation. She criticizes the war and Robb's involvement in it. She challenges him and he likes it. She travels with Robb's army and the two become closer. After Catelyn betrays Robb by releasing Jaime Lannister in the hope of retrieving Arya and Sansa, Talisa comforts Robb. The two sleep together. Because he genuinely loves her and cannot bear to see her dishonored by his own indiscretion, Robb marries her. It's a beautiful story. Except for one thing: Robb had previously promised Walder Frey that he would marry one of his daughters in other to grant his army passage across the Twins. And Walder Frey is not going to be to happy about Robb's marriage to another woman. Yes, Robb marrying Talisa was the single biggest mistake of his life and would ultimately lead to his death, along with the death of his wife, mother, and most of his army. With this one boneheaded move, the Young Wolf who had previously won every battle his army had engaged in during the War of Five Kings would doom House Stark's claim to Winterfell, the North's involvement in the war, prevent Arya from being reunited with her family, and ensure Joffrey and House Lannister's hold on the Iron Throne. And all for "firm tits and a tight fit."
