5 important things you probably missed on this week's 'Game of Thrones'

Warning: spoilers ahead for Sunday's episode of "Game of Thrones," "Blood of My Blood."

"Game of Thrones" took us through an exhilarating, and somewhat confusing, hour on Sunday that saw the past either come back to haunt the characters or empower them.

Bran Stark (Isaac Hempstead Wright) got a little of both. He was thrown by an assortment of historical images of the Seven Kingdoms and then woke up to find that someone from his past was back to protect him. Daenerys (Emilia Clarke) also got help after reuniting with one of her dragons and pulling from the past to mobilize her Dothraki subjects.

Meanwhile, Sam Tarwell (John Bradley-West) returned to his family home to a chilly reception. Arya (Maisie Williams) got caught up on the Lannister happenings through watching street plays and then decided on a new path for herself. And another character from the past came out of the darkness.

With all the comings and goings, there may have been some details that viewers didn't catch.
