The script shows cut moments which would have explained what Bran was doing during "The Long Night.
A commonly asked question after "The Long Night" was, "What exactly was Bran doing?
After Bran's eyes go white when he skinchanges in the godswood, the script says we were going to see "a massive flock of ravens, bigger than last time [episode 705], converge on Winterfell from all sides, all piloted by Bran.
Then, from the ravens' point-of-view, Bran would have seen Jon Snow on Rhaegal nearby, and also Daenerys off in the distance on Drogon.
Bran was effectively helping scout the location of all the troops during the battle.Or at least that's what the script makes it seem like he's doing.
Instead, the show's version goes from Bran skingchanging to the ravens flying by the Night King, and then never returned to other vantage points to indicate how Bran was tracking the ongoing battle in Winterfell.
