However it has now been revealed this was originally supposed to show off key parts of the battle to Bran.
The scripts, which have recently been made available for viewing at Writers Guild Foundation Shavelson-Webb Library in Los Angeles, reveal a lot was supposed to occur from these ravens.
During the script for episode three, it tells of Bran warging into the flock to get a handle on what is going on.
It read: “A massive flock of ravens, bigger than last time [season seven, episode five], converge on Winterfell from all sides, all piloted by Bran.”
