One of the important characters in Game of Thrones is Tyrion Lannister acted by Peter Dinklage. He turned into a crucial role in the series. In the season 1 of the show, his name appears last after all the other characters like Ned Stark, Catelyn Stark, Cersei Lannister but from season 2 to season 7, his name appears first even before Emilia Clarke (Daenerys) or Kit Harrington (Jon Snow) who have bigger roles i.e., competitors to the throne.

Generally, most important character names are given first in the titles in movies and TV shows. So, is this a hint that Tyrion is an important character than Cersei, Jaime, Jon Snow?
Why is his place in the order of characters changed to first even though there are other important characters than him? Is this a hint that his role has increased importance of his role from season 2? Or is there an out of universe reason for this? Is there a word from the directors or the producers regarding this?
