The Queen of Thorns finally returned to Kings Landing from Highgarden this week, set for a showdown with Cersei and intent on clearing the name of her grandson, Loras. Lady Olenna has built up a formidable reputation as an acid-tongued master tactician, wholl plot and scheme behind your back and to your face without you realising any of it has happened. Unfortunately for her, this week, she was bested by a combination of Cersei and the Faith Militant. So why is she so high on this list? Olenna isnt going to take a beating lightly, and this is only going to serve to increase just how cunning and ruthless we get to see her being. Plus there was her totally sick burn on Cersei: Cersei: "The famously tart-tongued Queen of Thorns." Olenna: And famous tart, Queen Cersei." Ouch.
