There is nothing more constant in the world than change. So they say. True, the Seven Kingdoms have their own laws. There, the constancy lies in the fact that the heroes of the saga are constantly dying (and not the easiest death). But still, from the very first season of the series, some things remain unchanged: Jon Snow is still frowning, Cersei and Jamie's relationship is still ... slippery, and Daenerys still cannot pacify her dragons. However, something has changed, and quite a lot: some actors have matured faster than their heroes; some were even replaced in a shameless way; someone lost some body parts (rest in peace, Jamie's hand), and someone completely disappeared. Let's see who has changed in these 4 seasons of one of the most sensational TV shows of our time!
