For one, Daenerys Targaryen (Emilia Clarke), aka Mother of Dragons, is the only person in possession of a live dragon and she also happens to be hell-bent on taking her rightful place on the Iron Throne. Could this be a spoiler about how her mission to swipe the throne from Cersei (Lena Headey) goes? TBH, it feels a little too on the nose, but that definitely looks like Drogon.
There is of course another (kinda) person in the Seven Kingdoms who is now the proud owner of a dragon—the Night King (Vladimir Furdik). In the season seven finale, he killed Dany’s beloved dragon and, after a rather labor-intensive effort from the wights, pulled him out of an icy lake and resuscitated him. There’s some debate about whether Viserion is currently a White Walker or wight, but he now has the tell-tale icy blue eyes of a dragon brought back from the dead. So, the likelihood that Viserion is the dragon in the pic and the Night King takes the throne is pretty small.
Another possibility? The dragon and the throne could be combined simply because there are dragons in the show and people like them.
Lastly, we’d be remiss not to mention the three lines in the “O” of GoT. These lines have been present in the show’s marketing since season one, but are particularly prominent on the season eight poster. Could they stand for the three heads of the dragon theory, or maybe the three major houses still in contention for the throne (the Starks, Lannisters and Targaryens)? Sadly, we don’t know.
As for who ends up on the Iron Throne, we’ll have to wait and see when Game of Thrones returns for its final season on Sunday, April 14, at 9 p.m. PT/ET on HBO.
