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.
Fans concluded the Targaryen genes were recessive, but when it came to children of a Targaryen male and non-Valyrian mother their first would be born with darker features, while subsequent offspring were blonde.
Though Rhaenyra is married to Laenor Velaryon, all three of the young princes have brown hair, instead of the signature platinum locks that the Targaryens and Velaryons are known for.
Rhaegar had his silver, white hair, while Lyanna had the dark hair. Jon has his mother's hair instead of his father's. Now 170 years in the past, Rhaenyra gives birth to three brown haired boys, instead of the signature Targaryen hair because they are bastard sons with the son of the hand of the king, Harwin Strong.
Rhaenyra has had a tough couple weeks. First, she finds out that her half-brother Aegon II has usurped the throne and that she will have to fight for her claim as queen. Then, she gives birth to a stillborn child. And finally she loses her second eldest son Lucerys to a dragon battle.
In 117 AC, Rhaenyra gave birth to her third son, whom Laenor named Joffrey, in honor of Ser Joffrey Lonmouth.
Prosthetic designer confirms: the baby was deformed
“When the babe at last came forth, she proved indeed a monster: a stillborn girl, twisted and malformed, with a hole in her chest where her heart should have been and a stubby, scaled tail. The dead girl had been named Visenya.
Aegon III, aka Aegon the Younger: Rhaenyra and Daemon's first child together.
It was rumored that those sons of Rhaenyra's were actually fathered by her lover, Harwin Strong, called 'Breakbones', as all three were born with brown hair, though Laenor and Rhaenyra both had light silver/gold hair.
If two brunette parents both have a recessive blonde gene, there's a 25% chance they'll each pass down their recessive gene, resulting in a blonde child.
It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up. If two brunette parents have a blond child, they had to have instructions for making blond hair hidden in their DNA.
Both parents must possess the gene for a red-haired child to be born. Redheads have fewer strands of hair on their heads. If they both just have the gene but have brown hair lets say then there is a 1 in 4 chance of having a baby with red hair. If red is the dominant hair color but the father has brown hair …
Viserra Targaryen was described as the most beautiful of Jaehaerys and Alysanne's six daughters who lived to adulthood, and was regarded as a "goddess" by some of the boys who met her.
Notes. ↑ Although The Princess and the Queen, published in 2013, stated that Rhaenys had silver hair, this was changed for the publication of Fire & Blood, where she is described to have had black hair, like other Baratheon descendants.
In the book, it says that Rhaenyra wasn't set to give birth for “another turn of the moon” but is induced into early labor after a fit of rage following the news of the coronation of her brother Aegon (totally merited).
Rhaenyra's baby died during childbirth.
According to the book Visenya, like Maegor the cruel's children, was born with scaled dragon-like skin and a small tail. Apparently, she was also missing her heart and instead had a hole in her chest.
The true parentage of Rhaenyra's three eldest children is still unclear. Despite these rumors, there was no doubt that King Viserys meant for Rhaenyra to succeed him as heir, and for her sons to follow her. By royal decree, each of Rhaenyra's Velaryon sons was given a dragon egg in the cradle.
Rhaenyra has been pregnant with her daughter Visenya since House of the Dragon's latest and last time jump, and it is heartbreaking to see her deal with this loss. The way in which the scene plays out makes it especially disturbing.
In 196 AC, the year of their marriage, she painstakingly produced a set of twins, Aegon and Aella.
The episode doesn't really beat around the bush when revealing that Harwin Strong (Ryan Corr) is the father of Rhaenyra's children. He's there soon after baby Joffrey is born so he can meet him, and later on in the episode Jacaerys (Leo Hart) even asks his mom if Harwin is his real dad.
That's right, during the Oct. 2 episode of House of the Dragon, Rhaenyra (Emma D'Arcy) and Daemon (Matt Smith) stopped fighting their feelings for one another and finally got together. However, this was more than just an illicit liaison, as Rhaenyra and Daemon got married at the end of the episode.
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.
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.
In House of the Dragon's season 1 finale, Rhaenyra learns about the tragic death of her beloved son Lucerys Velaryon, after having sent the young boy to deliver a message to Lord Borros Baratheon.
Daemon and Rhaenyra share two children together: Aegon III and Viserys II.
