A lot has been made on Game of Thrones of Daenerys (Emilia Clarke) allegedly being the last Targaryen to survive Robert Baratheon's (Mark Addy) quest to wipe out the bloodline. But what if Dany's family is still out there - and hiding right underneath our noses?

If you're at all familiar with Game of Thrones theories, you've probably heard of R+L=J, which predicts that Jon Snow (Kit Harington) is actually the son of Rhaegar Targaryen and Lyanna Stark. That would make Jon Dany's nephew and the cousin of the Stark children, as opposed to their illegitimate half-brother.

But what if Jon isn't the only other Targaryen out there? We explain why Tyrion (Peter Dinklage) and Hodor (Kristian Nairn) - yes, Hodor - might also be secret Targaryens in the video above.

Who do you think is actually a Targaryen?

Game of Thrones airs Sundays at 9/8c on HBO.
