Game of Thrones fan theories are just as beloved to the show's actors as the fans who made them.
Actors Kristian Nairn and Daniel Portman, who play Hodor and Podrick Payne respectively, both have their favorite theories, and while they'd love to see some of them come true, the show's material seems to be somewhat set in stone. One big theory revolved around Podrick being the secret child of Tyrion Lannister and his long-lost first love.
"In theory, it would be nice and really, really cool to tie things up in that way," Portman said. "But I don't think there's any chance of it. A lot of the theories are very, very far-fetched. We've got a whole show, we likely won't go back on something so inconsequential."
As for Nairn, his favorite fan theory is that Hodor is a long-lost Clegane child, sibling to Gregor "The Mountain" and Sandor "The Hound" Clegane.
As far as the upcoming season five of the show, Portman hinted that we'd see more of Podrick and Brienne of Tarth on their search for the Stark daughters. He said the two will grow together and continue to stick together as the season moves forward. When asked about it, neither would comment on the rumored appearance of Lady Stoneheart, a character cut from season four that plays an important role in the books.
In response to a fan question about whether or not they think HBO will finish the show before author George R.R. Martin finishes the book, Portman said that it was very possible, but not an entirely bad scenario. Portman explained that Martin had been approached before about adapting A Song of Ice and Fire for screens, but refused, finally settling his trust on HBO showrunners David Benioff and D. B. Weiss. Even if Martin's series never gets it final installment, the author feels his material is in good hands.
"If it happens, it happens," Portman said. "But he trusts them."
