The head of the Frey clan is a character with zero redeeming qualities: a nefarious old monster who had relatively minor political grievances with his allies, so betrayed their trust and had them brutally murdered in front of each other as revenge. That's not really on. Ever since the 'Red Wedding', he's kind of fallen off the radar, but there has to be some sort of resolution to a long list of moral misdemeanours. Maybe - hopefully - Arya will catch up with him eventually. Expertly cast, with Harry Potter's David Bradley playing the role, you'd be hard pushed to find a slimier so-and-so than this one. Aside from his actions at the 'Red Wedding', he also failed to fulfil an oath to come to Robert Barratheon's aide, preferring to wait the battle out, in case Robert lost. There's also his penchant for taking teenage wives, despite the fact that he's supposed to be 90 years old.
