OK, Game of Thrones fans, it looks like we might actually find out who the prince who was promised is before Season 7 is over. There was a bit of talk about it in Episode 2, including a helpful gender clarification from Missandei.
Combined with this shot of Gilly reading a book that seems to be about Azor Ahai, it's likely these clues will come to fruition sooner rather than later.
For those a little hazy on the details: Azor Ahai/the prince who was promised is a mythical figure who fought against the darkness in the past, and is prophesied to be reborn to save the world once again.
There are A LOT of theories about who this saviour will be in Game of Thrones, so we thought we'd rank them from least likely to most likely.
