I found the true pink letter on westros.org forum.
Reader
Your false plot is dead, reader. It and all its characters were smashed in 10 weeks of episodes. I have its ending. Tell its author.
Your false plot's themes are dead. Their metaphors smeared upon the walls of Winterhell. Come see them, reader. Your false plot lied, and so did George RR Martin. You told the world Sansa was getting smarter. Instead she went to Winterhell to be raped by Ramsbo.
I will have my shocking moments back. If you want the ending to your story, come and get it. I have it on HBO for all the world to see, proof of your lies. The network is greedy, but we have made a promise to spoil the 7 terrible books that started this series in Winterhell.
I want my gasps back. I want the false plots canon. I want to remove as many fantasy elements as possible. I want more whores.
I want to exploit them, their naked bodies. And I want my Saint Tyrion. Send them to me, reader, and I will not trouble you or your nerd friends. Keep them from me, and I will cut out your storys heart and eat it.
Benioff the Arrogant,
Trueborn author of A Song of Ice and Fire.
