Ultimately, Rhaenyra has two husbands (not at the same time) and gives birth to six children.
Rhaenyra will have two marriages (and two lovers) in House of the Dragon, with six children (technically three by each husband, the suspicion that the first three are by another man is a source of much violence and discord in Westeros).
Rhaenyra marries twice in the books, at first to Laenor Velaryon. In true Targaryen fashion, she marries her cousin so that they join forces with House Velaryon.
Who is Rhaenyra's second husband? Daemon Targaryen, younger brother of King Viserys I Targaryen and uncle to Princess Rhaenyra Targaryen, weds his niece shortly after the loss of her first husband and his second wife.
But, while time may heal all wounds, 10 years certainly wasn't enough time for Alicent's wounds to heal over being lied to by Rhaenyra. We last saw her find out the truth in "We Light the Way" that Rhaenyra lost her virginity to Ser Criston Cole (Fabien Frankel).
The story of the princess and her valiant knight did not end as a fairy tale, though. A sordid and controversial story began to spread that Rhaenyra lost her virginity to her uncle Daemon at age 16. No one knows if that is true. But Targaryens had long married within the family to keep their bloodlines pure.
After Daemon's first wife dies, he gets together with Laena Velaryon—who was initially suggested as a bride for King Viserys. They have two daughters. Meanwhile, Rhaenyra marries Laena's brother, Laenor Velaryon, and they have several kids.
Rhaenyra Targaryen (Emma D'Arcy) and Daemon Targaryen (Matt Smith) finally had sex on House of the Dragon. After teasing their deep connection for weeks, making out in a brothel, and flirting their way through King's Landing, uncle and niece at long last did the dirty.
In "Fire & Blood," Rhaenyra's longest-lasting relationship is with her uncle, Prince Daemon Targaryen. In addition to the age gap and the incest, their relationship starts off on an especially controversial foot, with rumors that he either seduced her or taught her to seduce Ser Criston Cole, resulting in his exile.
Although Rhaenyra's mother's death initially made her fear the notion of bearing heirs, adult Rhaenyra Targaryen now has five sons in House of the Dragon – three healthy boys with Laenor Velaryon (fathered by Harwin Strong) and two silver-haired boys with her husband Daemon Targaryen.
In George R.R. Martin's book Fire & Blood, we are told of the incident where Rhaenyra Targaryen's husband Laenor Velaryon dies while attending a fair in Spicetown, on the island of Driftmark. We learn he was “stabbed to death” by a knight in his father's service, his paramour Ser Qarl Quarry.
Corr continued: "For an audience to believe us, we have to show all shades of the character. So we spoke about that in great detail and Miguel and Ryan also made it paramount that Harwin very much loves Rhaenyra. He lives his life in service of this love and of his family."
Back in her chambers, Rhaenyra's gaze lands on the handsome Ser Criston Cole (Fabien Frankel). After some initial reluctance by Criston, who has much more on the line as a lowborn member of the Kingsguard, Rhaenyra playfully seduces her long-standing crush and they have sex.
— then Rhaenyra officially loses her virginity to Ser Criston Cole. After Daemon leaves Rhaenyra all horned up and alone, she sneaks back into the castle and lets Ser Criston see her in her page boy disguise.
Also, he may have realized the gravity of the situation (he was about to become very intimate with his niece in a brothel) and felt some sort of guilt and shame. These things mixed together, making Daemon physically and emotionally unable to complete what he set out to do.
By House of the Dragon's fourth episode, Rhaenyra is around 18 years old and Daemon is 34. "The idea that a teenage girl is in any way able to consent to that sexual interaction is a mess.
In George R.R. Martin's fictitious history of the Targaryen family, we learn that Rhaenyra does eventually have children with her uncle Daemon: two boys named Viserys II and Aegon III, both of whom eventually become king.
Turns out, Rhaenyra and Daemon are endgame, meaning they have a sexually tense relationship, eventually hook up, and get married—which is pretty significant from a power play perspective considering (1) they both want the throne and (2) their Targaryen union is almost sure to guarantee that happens—even though Alicent ...
Since Daemon's body was never recovered from the Gods Eye, singers say that he lived to spend the rest of his days in secret with Nettles. Daemon never achieved his ambition to sit on the Iron Throne, though his sons Aegon III and Viserys II eventually did.
Rhaenyra and Daemon's sons Aegon, Viserys, and Visenya Targaryen. Sorry for the spoiler, but we did watch Daemon and Rhaenyra get married in last week's episode, so you probably knew this was coming! We haven't seen them yet in the show, but Daemon and Rhaenyra have three sons together.
Some dragon-like babies are born after incredibly complicated and anger-induced births, so it's possible that the fire of the dragon being released within both Rhaenyra and Syrax during the birth somehow impacted her daughter's physical characteristics.
Rhaenyra's three eldest sons all died fighting during the Dance of the Dragons, but her two youngest sons, the sons by her second husband, Prince Daemon, survived the civil war.
During her short reign, the taxes were raised every day to fill up the treasury, while she grew fat due to her gluttony during her reign. In the end, the people of King's Landing turned on her and named her “King Maegor with teats”.
