She represents the Lightbringer, which seems to be an even newer god. Possibly something to do with the comet?
I thought the Dragons returning was the meaning. ie Khaleesi
Also, the red headed crazy witch woman with Stanis, does she represent the old gods? Or just some other God? And she was burning the new 7 Gods right?
Joffrey is turning into Darth Vader.
HOLY FUCK AT THE ENDING
Why were the killing all the younglings at the end?
Real answer: the episode's bodycount was way too low.
Real real answer: presumably it was ordered by the Joff or his mom to hide potential evidence of his real daddy.
