The characters of "Game of Thrones" have changed so much from the sweet summer children of Season 1. Season 7 has been treating fans to so many reunions and early season callbacks, giving us nostalgia for those relatively simpler days while building excitement for the winter wars to come.

GoT started filming in 2010 for its 2011 premiere, with most of the Stark actors starting as teens or even preteens. Now they and their TV alter egos are adults. You can see how 10 of the show's main characters have changed in these images created by the folks at the betting site sportsbettingexperts.com, showing Tyrion Lannister, Daenerys Targaryen, Arya Stark, Jaime Lannister, Petyr "Littlefinger" Baelish, Cersei Lannister, Bran Stark, Jon Snow, Theon Greyjoy, and Sansa Stark.

Game of Thrones Character Evolution

Those baby-faced kids are all grown up! But you could argue that Cersei is the one whose appearance has changed the most.

Believe it or not, Season 7's seven episodes are almost over already, and then we'll only see these characters again for the six episodes of Season 8. How much will they have changed by the finale? We're not expecting all of them to make it that far...

GoT Sesaon 7 continues Sundays at 9 p.m. on HBO.
