House of the Dragon is a great show! I just wanted to preface that fact before I said anything else. I cannot tell you how much it pleased me that Ryan Condal and George R. R. Martin not only released a creative experience, but a faithful one as well. I didn’t read any of the books mind you, as I am not much of a reader, but the general tone that I get from the comments made under posts on YouTube and in different subreddits tell me that it’s in a good place so far.
In a later episode, we’re introduced to Dreamfyre, a dragon that evidently belongs to Princess Helaena Targaryen. I’m not entirely sure if there is a bond between the two, as no scenes depicted her riding Dreamfyre, nor any interactions between them have been observed on screen. I only know that Dreamfyre is her dragon. Perhaps in later episodes, I’ll get to see some form of cooperation that dragon riders have with their dragons concerning these two.
