"Oh, hum.. Yeah.. Well let's just make Dany go full-on mad queen and burn king's landing to the ground, killing Cersei in the process.. But make it last an entire episode.. and umm.. Jon can kill Dany, and we need to somehow get rid of the throne.."
"We still have a dragon left?"
"Perfect!"
"..and the rest?"
"Meh.."
