Stephen King has revealed his prediction for the "Game of Thrones" finale. The acclaimed horror writer is a huge fan of the HBO show, which is in its final season. In a new tweet, King believes Tyrion Lannister will be on the Iron Throne when the show ends. Tyrion is played by Emmy and Golden Globe-winning actor Peter Dinklage. The character is also "Game of Thrones" author George R.R. Martin's favourite in the book series. A lot of unexpected events would have to happen, but King's prediction is certainly possible.
