Game of Thrones cameos: Ed Sheeran, David Benioff, D.B. Weiss

In the season 8 premiere, “Winterfell,” the It’s Always Sunny in Philadelphia star and co-creator got an arrow through his eye as Theon and crew snuck aboard Euron’s ship to save Yara. McElhenney’s cameo isn’t a huge shocker considering his relationship with GoT creators David Benioff and D.B. Weiss goes back years, with the duo even writing a 2013 episode of Always Sunny.
