There’s a quick scene of the white walkers approaching the gate. They must meet up with the Night King en route to the Godswood.I was thinking today. Where did the Night King's white walker buddies come from? We see him leaving Jon to be overrun, as he closes in on the gates to Winterfell.....all by himself. He goes inside. None of his buddies are seen in any of the battle scenes inside Winterfell, yet when he comes up to Bran he has his full posse with him.
