Ser Criston Cole
Here’s a fascinating fact: despite the fact that Rhaenyra and her protector knight Ser Criston Cole appear to have a deeper relationship in the book, they never sleep together. He’s still as guilty and honor-bound as he was on the show. He’s also described as having “coal black hair and pale green eyes,” which looks a lot like Fabien Frankel in House of the Dragon. Similarly, he’s depicted as being just as proficient with a sword as he is in the show.
Rhaenys Targaryen
While there aren’t many detailed physical descriptions in Fire and Blood, Thaenys Targaryen is clearly mentioned as having Baratheon black hair and Targaryen violet eyes. Her hair remains black with white streaks throughout as she ages. Interestingly, they decided to maintain neither for the program, despite the fact that actress Eve Best has dark brown hair. Our best assumption is that she had her hair dyed white to make it clear to the audience that she was a Targaryen. We still think she did an excellent job as the Queen Who Never Was.
