Sheeran's missable appearance on the show last year irked more than a few fans who couldn't understand why he popped up to serenade Arya and didn't even die afterward. The cameo didn't sit right with Hodor, Kristian Nairn, either.
In an in-depth interview this month, Nairn told HuffPost, "I'm not a fan of the cameos in 'Game of Thrones.' I don't like them. I think it's stupid. I don't mind going on the record on that. I just think it takes you right out of the world."
"Especially Ed Sheeran," he said. "I was like, 'Why is Ed Sheeran here?' I mean, Ed Sheeran's great. He's a great guy, great musician, but why is he in 'Game of Thrones'?"
The controversial cameo is in the Season 7 premiere, when Arya (Maisie Williams) happens on a group of soldiers en route to King's Landing.
"I'm not saying I'm not a fan of Ed Sheeran," Nairn clarified. "I'm being tactful here, but just not a fan of the cameo. I think most people would agree with me there. It was a big snap to reality. It's like, 'What? What?'"
He added, "It's a fantasy show. We're all caught in this amazing world and spend so much time and money and talent to create, and all of a sudden there's a pop star? What?"
In the scene, Sheeran plays a Lannister soldier sitting with a few comrades when Arya shows up. Keep in mind that earlier in the episode, she murdered a bunch of Freys as revenge for the Red Wedding (which was orchestrated with the Lannisters).
Watching it unfold, you wonder, "Oh, is Arya about to go class A-Team and crumble his face like pastries?"
But no. Instead — just in case you weren't absolutely, positively sure that the guy who looks exactly like Ed Sheeran is the real Ed Sheeran — he sings a song.
Repeat: Ed Sheeran shows up and sings a song.
"It's a new one," he says.
Fans proceeded to unload relentless ire. Puns were made. Memes were born.
There was a rumour that Sheeran left Twitter because of the online wildfire. But he denied it, saying he had always planned to abandon the platform and his cameo was "clearly f**kin' awesome."
If you weren't in love with the moment, look, it's not all Sheeran's fault. He was reportedly cast in the show as a sweet surprise for Williams, who's a fan. And there were plenty of other cameos before his.
To name a few: members of the metal group Mastodon appear in the Season 5 episode "Hardhome," reprising their roles in Season 7 as wights; Of Monsters and Men strum instruments in the background of the play Arya watches in Season 6 (and weighed in on an Arya theory for HuffPost); and Sigur Rós shows up at Joffrey's wedding in Season 4, which was the only cameo Nairn could get behind.
"[Sigur Rós] kind of got away with it because they're so quirky ... They're almost like 'Game of Thrones' world in real life. They're so elven and spiritual. I think that works, but apart from that — I mean, I understand why people want to be in it, but just no. Go away."
