The Quote: "You're no son of mine!" On any other show, Tywin Lannister would be a shoe-in for the title of worst dad. But on Game of Thrones he must settle for merely awful. The consistent victim of his bad parenting is his youngest son, Tyrion. Tywin is utterly indifferent to Tyrion's well-being and even seems to actively put him in harm's way. After being put on trial and sentenced to death by his father, then finding out that he was also sleeping with his son's lover, Tyrion decides to end the abuse. He finds his father on the chamber-pot and puts an arrow in his gut. Instead of seeing the error of his ways, Tywin uses his last moments to once again show what a deadbeat dad he is. Even though this is Tywins death scene, its arguably a more important scene for Tyrion. In the whole series, Tywin was the one character that Tyrion could never stand up to. Sure, he made the occasional witty comment to anger his father, but Tywin ruled over Tyrion his whole life even while continuously disowning him. Here, we finally see Tyrion standing up to his father and making him pay for his years of mistreatment. Tyrion responds to his father's words by asserting he is his son and always has been. Nothing Tywin says can change that or excuse how he treated Tyrion all those years. He truly deserves his humiliating death.
