The true gift to Williams would be if Sheeran was a musician that Arya Stark had to take out on her revenge quest. Also, unrelated, but we would watch a show that's entirely Arya Stark going around and effecting knifepoint diplomacy on all the evil men of Westeros. You know there is no shortage of awful people on Game of Thrones, and we want Arya to personally dispose of all of them. Literally why not? We have a reality star president. There are no rules anymore.
