Warning: This article contains spoilers for Fire & Blood and A Knight of the Seven Kingdoms by George R.R. Martin, and thus, future seasons of House of the Dragon.House of the Dragonis the firstGame of Thronesspinoffto debut after the original series, but its four-season plan ensures it won’t end for some time — andA Knight of the Seven Kingdoms: The Hedge Knightis poised to spoil its conclusion.A Knight of the Second Kingdomsis the secondGame of Thronesspinoff coming to HBO, and the series is slated to premiere in late 2025.The Hedge Knight’s release windowconfirms what those familiar withGeorge R.R. Martin’s booksalready suspected: that the show will reveal the outcome ofHOTDbefore it happens.
Although viewers know some of the aftermath of the Targaryen civil war fromGame of Thrones— most notably that it diminished the power of House Targaryen and the number of dragons in Westeros — the entire ending may not be clear to every viewer. Joffrey Baratheon doesspoil Rhaenyra’s fate inGame of Thrones,but it’s during a conversation that’s easy to overlook, especially without any real investment in Targaryen history.The Hedge Knightwill also reveal what becomes of the Blacks and the Greens, but two seasons intoHOTD,this will be more noticeable.

The Hedge Knight Book Spoils How Rhaenyra Dies & Who Becomes King
A Passage From George R.R. Martin’s Book Confirms Aegon III Becomes King
A Knight of the Seven Kingdomsis based on Martin’s book of the same name, and it’s set betweenHouse of the DragonandGame of Thrones.This alone sets the show up to spoilHouse of the Dragon, as the details of its timeline will offer clues about how the Dance of the Dragons turns out. However,Martin’s book also outright states the outcome of Targaryen civil war. For one, it confirms that Aegon II becomes king again. When Dunk learns Egg’s true identity, he asks him, “How many Aegons have been king?” The squire tells him, “Four Aegons.”
House Of The Dragon’s Perfect Replacement Show Can Be Set Up By The Next Game Of Thrones Spinoff
House of the Dragon season 4 will be the show’s last run, but one part of Game of Thrones history lends itself to being a perfect successor show.
Since Egg is only the fifth Aegon Targaryen, it stands to reason that every Aegon thus far has been king — including Viserys' son inHouse of the Dragon.Of course, he does claim the Iron Throne during the early days of the Dance of the Dragons, so this line alone could be glossed over. ButA Knight of the Seven Kingdomsalso contains a passage referencing Rhaenyra’s fate, though it doesn’t mention her by name. When Dunk remembers how Ser Arlan would tell him stories of the last dragon, he recalls the man saying, “Some say King Aegon poisoned her.”

Arlan clarifies that he’s talking about the third Aegon, who “was afraid of dragons, for he’d seen his uncle’s beast devour his own mother.” The fact that he needs to specify between the two King Aegons indicates that the second one will be on the throne again later on. It also reveals howhe manages to reclaim power: by feeding Rhaenyra, Aegon III’s mother, to her own dragon. It may confuse viewers that Rhaenyra’s son ends up on the Iron Throne, too, but that’s the result of him marrying Aegon II’s daughter, Jaehaera, in an attempt to reunite House Targaryen.
AssumingA Knight of the Seven Kingdoms’adaptation includes these conversations, it will be obvious howHouse of the Dragonends well before its final season.

After all,these scenes will show up inThe Hedge Knight’s one and only outing in 2025. Based on the two-year gaps between seasons ofHouse of the Dragon,its final episodes won’t arrive until 2028 at the earliest.
A Knight Of The Seven Kingdoms Shouldn’t Worry About Spoiling House Of The Dragon
Although some viewers may be frustrated ifA Knight of the Seven Kingdomsgives awayHouse of the Dragon’s ending,the nextGame of Thronesspinoff shouldn’t worry about spoiling things. The original series gives away the outcome ofHouse of the Dragonanyway,and it’s even more crucial thatThe Hedge Knightdoes so. The references to Targaryen history are critical toA Knight of the Seven Kingdoms,and that includes those discussing the Dance of the Dragons and the absence of dragons that follows.
Including these details sets up the world the Targaryens find themselves in duringA Knight of the Seven Kingdoms.

Including these details sets up the world the Targaryens find themselves in duringA Knight of the Seven Kingdoms.It also contributes to Egg’s individual character arc. Egg becomes determined to bring the dragons back, and the Targaryen history established inHouse of the Dragonadds necessary context to his obsession. It would be a shame to lose that just to avoid spoilers.
