  ===Season 4===
  Margaery Tyrell has been married to Joffrey Baratheon, but she is widowed hours later when he is poisoned at the wedding feast. Soon after, Olenna reveals herself as masterminding the poisoning, but Margaery, now aware that Tyrion Lannister's trial is a farce, keeps quiet. Arrangements are made to wed Margaery to Joffrey's younger brother Tommen, to whom Margaery swiftly ingratiates herself. Cersei and Margaery continue their bitter rivalry; Cersei resents being displaced as Queen and being forced to marry her very young child to the much older Margaery, while Margaery tries to outmaneuver her.
