It was mercy for Alicent because she could have just had her killed like her father wanted.what an amazing episode
the only thing I didnt like, was what made GoT so amazing in the first place was no one was safe from plot armor, which is what to me ruined season 7 and 8 ultimately.
This all could of been ended by having the dragon eat Aegon or Alicent or Otto.
But all this just to flex ? Cool scene, amazing episode, but she could killed Alicent right then and there and didnt or otto or anyone she wanted
