Laenor and Rhaenyra had three sons together: Princes Jacaerys 'Jace', Lucerys 'Luke', and Joffrey 'Joff' Velaryon.
Daemon, Rhaenyra and Alicent have 11 kids among them by the eighth episode, which is set about six years after the "Driftmark" episode.
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.
Jacaerys Velaryon Is Rhaenyra's Firstborn Son and Heir
Firstborn son of Rhaenyra and her first husband Laenor Velaryon, Jacaerys was affectionately known to his family as Jace.
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.
The comes the final blow: Rhaenyra's baby daughter – whom they'd named Visenya, according to George R.R. Martin's Fire and Blood – is stillborn after a brutal, bloody labor. This is similar to the book, where the baby also has dragon-like birth defects, including a hole in her chest and a small tail.
Eventually, it's Daemon and Rhaenyra's two sons who end up sitting on the Iron Throne, but is that for a future series? The Velaryons survive, but in recent years Ser Corlys has come to support the Greens, after falling out with Rhaenyra and being accused of treason (unfairly).
Alas, the baby did not survive and while it wasn't shown very well on camera, there were debates among fans whether the baby was normal-looking or deformed.
“The Princess and the Queen” opens up with Rhaenyra giving birth to her third child, another boy. Laenor decides they'll name him Joffrey after his late lover who Criston beat to death right before he and Rhaenyra wed.
In the book, Visenya was described as being born with dragon-like defects, including scales, a tail, and a twisted body. Rhaenyra's baby did end up having scale-like defects and a malformed body in House of the Dragon, which aligns with the occasional reports of Targaryen women bearing dragon-like stillborn children.
One of the first times we see Rhaenyra as truly angry throughout the entirety of Season 1 is during the traumatic miscarriage of her daughter Visenya.
Like Laenor Velaryon's sexuality, it was a “known secret” in the Red Keep that Harwin Strong was the father to Rhaenyra's three children: Jacaerys, Lucerys, and Joffrey.
Born at the start of episode 6, Joffrey is Rhaenyra's youngest child, for now, and only a baby — and therefore pretty unremarkable on his own terms.
It isn't explicitly stated in the show, but because we learn after episode six that all three boys have dark brown hair — and despite Rhaenyra and Laenor's matching blond color — it has been strongly implied that they are actually the children of Ser Harwin Strong, the Lord Commander of the City Watch.
Rhaenyra and Daemon's Marriage
Soon after being widowed, Daemon and Rhaenyra marry each other in secret when he is 39 years old, and she is 23. Their marriage causes a huge scandal at court and another rift between Daemon and Viserys, but it is eventually accepted.
The shock of the loss of her father, combined with the Greens' ruthless betrayal sends her into early labor. Without modern medicine, a baby born so early had very little chance of survival in the best of circumstances - and in these terrible conditions the baby, a girl named Visenya, is stillborn.
Rhaenyra doesn't just lose her baby, but this happens in an unnecessarily long and detailed scene that could have been dedicated to literally anything else. It is a mind-boggling choice, and just the first of the violences enacted upon her in the finale.
Rhaenyra cradles her daughter and weeps. Though the Silent Sisters come to prepare the body, Rhaenyra wraps her child in funeral cloths by herself. Visenya is cremated on Dragonstone just as Ser Erryk Cargyll arrives with the crown of King Viserys I, and Rhaenyra is crowned queen at her daughter's funeral.
After the assassination plot against Laenor Velaryon, which led to the widespread belief that he had been killed (though a brief scene at the end of "Driftmark" reveals that he and his romantic partner, Ser Qarl, have fled Westeros), Princess Rhaenra married her uncle Daemon, and they have had two children, Aegon III ...
Nonetheless, Rhaenyra and Daemon's youngest son becomes King Viserys II Targaryen, with the crown passing through his line. New episodes of House of the Dragon release Sundays on HBO/HBO Max.
Episode 6 also shows Rhaenyra's eldest son, Jacaerys, reconciling with the fact that his paternal bloodline lies with House Strong rather than House Velaryon.
Aemond killed Rhaenyra's son after a dragon chase through the rain, before which Aemond laughed and tried to cut out Luke's eye. The pursuit culminated in Aemond losing control of his dragon, which brutally chomped Luke and his dragon.
Age = 2 years 6 months in episode 4: When Daemon returns from the stepstones, it's assumed that around 6 months have passed from the events of episode 3.
He died during the Storming of the Dragonpit trying to ride Syrax, his mother's dragon, in order to save the dragons in the Dragonpit, but the dragon rejected him and he crashed to the ground, dying instantly.
