Are they gonna change the storyline due to the high expenses?
If so, would Jon snow lead the army and destroy Lannisters?
But then there comes the Dragon mother , what would happen to her in the sea
According to the trailer it looks like Jon snow is on the the wall fighting against wildings with the help of Stannis.
They might change the storyline not due to high expenses but due to slow writing speed of rr martin.
Calesi will lead to defat lannisters, White Walkers would be a vital effect... have no idea about starks...
