History tends to repeat itself, as author George R.R. Martin has taken great pains to spell out throughout his original novels. When “Game of Thrones” was still in its early seasons, readers of the “A Song of Ice and Fire” series anxiously awaited the show’s adaptation of Martin’s bloodiest and most horrific plot twist: the infamous Red Wedding that wiped out several of our favorite heroes at once. Nothing can quite measure up to that level of wanton destruction, of course, but those who’ve read Martin’s “Fire & Blood” knew that “House of the Dragon” had a relatively comparable tragedy waiting in the wings. Rather than the devious Lannisters sending their regards, those responsible for this unspeakable murder happen to be pair of monsters known only as Blood and Cheese.

In the series, as well as the book, fans can only sit by helplessly and watch as terrible characters do terrible things in the so-called Dance of the Dragons. In both versions, it’s Daemon’s nasty idea to exact revenge (“An eye for an eye, a son for a son,” as he puts it) through the most underhanded means. With the help of his one-time paramour and spy Mysaria (Sonoya Mizuno), Daemon recruits a renegade member of the City Watch and a rat-catcher working in the Red Keep to navigate the hidden passageways of the castle, make their way to the royal apartments, and strike at the very heart of Team Green’s family. In “Fire & Blood,” their intended target is King Aegon (Tom Glynn-Carney) and Queen Helaena’s son. In the series, this is altered slightly to be Aemond himself; failing that, however, Daemon strongly implies that murdering Aegon’s son remains a suitable Plan B.

Tragically, Blood and Cheese accomplish their bloody mission.
