Aside from the now-canon fan theory that Jon Snow’s real parents are Rhaegar Targaryen and Lyanna Stark, the most popular Game of Thrones fan theory concerns how Cersei Lannister will die. Most assume that it will be at the hands of her twin brother and lover Jaime Lannister. But Nikolaj Coster-Waldau, who plays Jaime, disagrees.
“It has a beautiful, romantic, tragic thing [to it],” he said in a recent interview. “It’s probably too obvious.”
The theory comes from the prophecy Cersei hears as a girl, which the show portrayed in Season 5. Recall a younger Cersei visiting a witchy woman in the woods — Maggy the Frog — who accurately foretold the deaths of her children. “Gold will be their crowns and gold their shrouds,” she said. Although the show skipped over this aspect in the books, her prophecy has a crucial second part. She tells Cersei that she will die at the hands of “the Valonqar,” which means “little brother” in High Valyrian.
Tyrion would be the obvious choice, as he’s younger, literally little, and hates Cersei. However, Jaime is the younger twin, and having him kill the woman he loves — committing regicide a second time, reinforcing his legacy as the Kingslayer — would be beautifully tragic.
It’s apparently too beautiful for Coster-Waldau, though. In any case, with that look he gave Cersei as she sat on the throne in the Season 6 finale, their relationship will hardly be smooth sailing in Season 7.
Game of Thrones Season 7 will premiere at an as of yet unspecified date in summer 2017.
