Not my idea I just wanted it to be out there. Brett Partridge mentions Tiger Tiger before he dies which is a common theme throughout the series. The poem Tiger Tiger comes from a poet by the name of William Blake. Is also done many paintings one of which is called the great red Dragon. Great red Dragon is the name of the episode eight in season six. Here's a coincidence. The great red dragon depicts a seven headed dragon coming out of the depths of hell. Make a long story short one of the heads is cut off and thought to be mortally wounded. The seven headed dragon represents a seven main characters and one of the heads mortally wounded that also represents Brett partridge. Lastly we find out that the head that was thought to be mortally wounded is actually still alive. This is a type of stuff that Bruno Heller does and I just think it's a big coincidence that this time so happens to be the title of the episode in which we also find red John. Thanks to listening to the theory guys.
