Okay so this one may be a little far-fetched, but considering 'Game of Thrones' has had smoke babies and resurrections, we'll go with it. There is a theory doing that rounds that Drogon could have dragon babies.

But Drogon is a boy, you say! Well, according to George RR Martin in his book about the history of the Targaryen dynasty, "determining the sex of a living dragon is a nigh on impossible task". And even if you can, in the 'Game of Thrones' books, dragons can also change their sex.

So maybe Drogon is a lady dragon?

This theory is backed by the fact that Drogon wasn't seen for a while in season 4, so could possibly have gone off to have babies.

And more importantly, there's this shot from the opening credits which show one large dragon surrounded by three smaller dragons.

Also, in one of the pics released from this week's upcoming episode, Euron is shown looking up to the sky with a surprised expression on his face. Surely seeing Drogon wouldn't warrant such a reaction?

We're calling it, dragon babies!* Huzzah!

*Probably wrong.
