"Matt's damn sexy in this show, he's the sexiest I've ever seen him," Frankel said.
Frankel also discussed the tournament scenes in episode one, where his character, Ser Criston Cole, first comes to blows with Daemon. Frankel said that after the scene, Smith suggested that there may be underlying feelings between the two characters.

Frankel recalled: "We had a blast shooting those scenes. We really liked each other a lot. I remember Matt saying, 'Maybe they're flirting, Criston and Daemon.' It's funny because I thought that in private but I didn't want to say anything in case it felt controversial."
There have only been two canonically queer main characters in the series so far, Laenor Velaryon and Ser Joffrey Lonmouth. However, the latter was killed in the same episode that he was introduced.
Fans have also theorized that Daemon's niece Rhaenyra Targaryen and her best friend Alicent Hightower have romantic feelings for each other due to their close friendship earlier in the show.
During a roundtable interview, which Insider attended ahead of the series, Emily Carey, who plays the younger version of Alicent, said that she thought the characters were "in love a little bit" when she first read the script.

"I think any woman could think back to the best friend that they had at 14 years old, and it's a relationship and a closeness unlike any other," Carey, who is queer, said. "You do toe the line between platonic and romantic."
