Emma D’Arcy Explains Helaena and Rhaenyra’s Final Moments (Exclusive)

House of the Dragon Season 3 was bookended with Targaryen deaths. The season began with the loss of Prince Jacaerys (Harry Collett), Queen Rhaenyra’s (Emma D’Arcy) heir, and a string of deaths of the royals and their allies, plus countless civilians and soldiers, followed. It all culminated in a destructive battle in Tumbleton, plus a tragedy in King’s Landing. D’Arcy explains why one finale death was a turning point from which “there’s no way back.” Warning: House of the Dragon Season 3 spoilers ahead!

Rhaenyra awoke in the Season 3 finale to learn that her half-brother, Aegon (Tom Glynn-Carney), had returned to some power with the revival of his dragon, Sunfyre. The beautiful beast had survived the battle at Rook’s Rest after all. Aegon flew to Harrenhal to accost his treacherous brother, Aegon (Ewan Mitchell), and band with him to take on Rhaenyra in the upcoming fourth and final season. Back at King’s Landing, his sister-wife, Helaena (Phia Saban), was still imprisoned in her room in the Red Keep, while mother Alicent (Olivia Cooke) was on her way back from her attempt to kill Aemond in Harrenhal.

The pregnant Helaena has been grieving the murder of her young child, Jaehaerys, all season. The boy was killed in Season 2 Episode 1, and Helaena was forced to point out the young prince to his killers. She and her daughter, Jaehaerys’ twin Jaehaera, were spared, but traumatized. Confinement in the Red Keep after Rhaenyra took back the throne worsened Helaena’s mental state, and her mother/fellow queen did little to comfort her. In fact, her efforts to comfort mostly made Helaena feel worse, as the younger queen was realizing how little she was understood and how often her wants and needs were betrayed or disregarded by her family.

Unable to overcome the grief of her son’s murder and bound to her room, Helaena’s mental health worsened. Her pregnancy was a source of hope at first, but the child had little hope for a good — or even long — life with Rhaenyra in power, especially if it were a boy who would threaten her claim to the Iron Throne.

The former queen started hurting herself with the needles used to make her prophetic tapestry, the updates of which were dictated by her prophetic dreams that painted out certain doom for her and her Targaryen siblings. When Helaena refused to eat, Rhaenyra had knights force-feed her, and Helaena told her sister that simply being alive is not enough to feel like you’re actually living. A life in captivity in comparison to death was little comfort.

Helaena killed herself in the finale’s last moments by jumping from a window of the Red Keep, her completed tapestry hanging from the ledge. Rhaenyra arrived at the scene, saw Helaena’s body and the deadly omens sewn into the tapestry, closed the window, and the season was over.

“Helaena is the moral heart of the show,” D’Arcy told journalists in a finale press conference. “She’s maybe the only character who has a proximity to power, but remains uncontaminated. Her death condemns Rhaenyra to the path she’s chosen. There’s no way back after that.”

D’Arcy said “there’s certainly no route back to a more moderate form of leadership” and that they “don’t know where we go from here, but I imagine it’s likely to be impassable in her relationship with Alicent, which I think also means Helaena’s death condemns Rhaenyra to be alone in her pursuit for power.”

Rhaenyra and Alicent have retained some sort of closeness throughout the season out of a residual love for their former close friendship as girls, but there was no real hope for the women to truly reconcile after Alicent usurped the throne in favor of her son, thinking it was King Viserys’ (Paddy Considine) dying wish. Alicent’s actions were done in earnest, but she didn’t stop her treacherous father, Otto Hightower (Rhys Ifans), when she learned that he and other men on Viserys’ small council had secretly plotted to steal the throne for Aegon in the time before the king’s death.

D’Arcy said that Alicent was like a judge for Rhaenyra in House of the Dragon Season 3. The queen would go to the captive Alicent and Helaena’s room to seek council and information. Intentional or not, Alicent has always had a hand in the events that led to the deaths of Rhaenyra’s sons, Jace and Luke (Elliot Grihault), as well as the premature stillbirth of her daughter, Visenya.

Rhaenyra became obsessed with finding proof of her divine right to rule to make sense of the deaths of her children. By the finale, the queen had descended into tyrannical behavior. While she’s a monarch with absolute rule, she’s displaying increasingly paranoid behavior that the creators of the series say could impact her judgment.

“It’s hard for me to say whether Rhaenyra recognizes Alicent’s culpability, because I’m not sure that Rhaenyra recognizes that her leadership is becoming increasingly tyrannical, at least not for most of Season 3,” D’Arcy told TV Insider. “I’ve really enjoyed their relationship this season. I think in part because there’s a nice thing where Rhaenyra’s constituent parts got externalized this year in some way. Daemon is the ego, Mysaria the conscience, and Alicent is the judge.”

“I really like the idea of locking your judge up in the basement, but then periodically going down to check in with them about how you’re doing,” D’Arcy said of Alicent. “Something about that feels very truthful, although it’s bizarre and abstract.”

House of the Dragon Season 4 is set to premiere in 2028 on HBO.
