Game Of Thrones: Is Tyrion Lannister Actually A Targaryen?
His Relationship With Daenerys And Her Dragons
After the meeting of Daenerys and Tyrion in Season 5, and her naming him Hand of the Queen in Season 6, the pair are closer than ever, and means that he'll be supporting her claim to the Iron Throne, and very much working with her dragons.
During Season 6, we actually saw Tyrion interact with two of Daenerys' 'children', Rhaegal and Viserion. He told them an incredibly charming tale about how he always wanted a dragon, even just a small one, and then freed them from their chains. And given they didn't burn him to a crisp and then devour him, it only adds further fuel to the fire that he could have some Targaryen blood running through his veins.
