Imagine how the Lady of Thorns is going to react to the “green judgement”? Methinks that - like Sansa was given the privilege of managing Ramsey’s demise, so will Olenna be given special permission to end Cersei’s “suffering”...
“Olenna be given special permission to end Cerseis suffering...”
She’s going to be too late, the woods witch’s prophecy said that Cersei would be strangled by the “valonquar” or little sibling, so the most likely candidates to kill her are Jaime or Tyrion (I’m thinking Tyrion because it’s hard to strangle someone with only one hand).
