Jon Snow came back to life in the latest “Game of Thrones” episode. This plot twist, while shocking, is probably something fans have already seen before. Did Game of Thrones Season 6 really rip off Jon’s revival from another show?

According to Collider, Jon’s fate does not seem to be the first time a show tried to make an already shocking character death “more shocking” through a revival. “The mystery of Jon maintained the same course as the mystery of Glenn,” Collider claimed. Glenn is a character from “The Walking Dead.” His seeming death earlier caused quite a backlash, as did Jon Snow’s death.

To be fair, Collider never did claim Game of Thrones Season 6 ripped off Glenn’s storyline. For one thing, Glenn didn’t really die. Fans were just led to believe that he did. In comparison, Jon did die and was only brought back to life. However, Collider said “Game of Thrones” has a lot to learn from the AMC series. “After what happened to Glenn, [Walking Dead] lost a bit of credibility…because of the manipulation of the fans by the hands of the producers,” the news site said.

Meanwhile, actor Kit Harington, who plays Jon Snow, revealed how hard it had been for him to keep his character’s fate a secret. “At first, I thought I would find it fun,” Harington told Entertainment Weekly. “But I had to lie to a lot of close friends and cast members and crew. The longer it went, the more I felt like I was betraying them.”

One of his co-stars even wrote him a heartfelt letter when he told them he was leaving. “Sophie Turner, bless her, wrote me a really long letter about how much she loved working with me,” Harington said. Turner plays Sansa, one of Jon Snow’s half sisters.
