GRRM isn’t doing anything? Writing no episodes?
He hasn’t been doing much on the show for years now. The showrunners are stuck coming up with material on their own now, based on a few notes that GRRM gave them of what may (or may not) happen in the books that GRRM hasn’t finished writing yet.
His lazy ass seems to be more interested in watching football or working on his side projects than actually delivering on his most successful product.
GRRM is too busy with his blog, selling action figures, attending fantasy conventions etc. Writing (good writing) is tough work, GRRM has umpteen millions in the bank and not much motivation to actually be an author.
