Dragons!

One thing is for certain: there will be dragons in season six and big ones at that. Daenerys' babies, gifted at her wedding, were seen briefly in season five, but the man behind the visual effects for Game of Thrones, Joe Bauer, told Yahoo: "For season six the dragons will again be double in size, spanning 120ft from wingtip to wingtip."

Are Tyrion and Jon part Targaryen?

When Tyrion Lannister shoots his father Tywin at the end of season four, Tywin utters: "You are no son of mine." Could this remark be more than a dying retort? Some fans and iDigitalTimes think so.

The theory holds that the Mad King Aerys II Targaryen had an affair with Tyrion's mother, Joanna, thus making Tyrion part Targaryen.  Another theory is that Jon Snow is not Ned Stark's illegitimate son, but rather the son of Ned's sister Lyanna and Daenerys's older brother, Rhaegar. On her deathbed, Lyanna asks Ned to promise her something – fans speculate that this could be a request to bring up her boy as his own. Could Jon follow in Daenerys's footsteps and emerge char-free from his funeral pyre in season six?

Jon and Tyrion's possible Targaryen connections are consistent with a theory that they are the other two dragon riders needed to reclaim the Iron Throne with Daenerys according to a vision she had in season three.
