Laena comforts her daughter Rhaena who is attempting to hatch her dragon egg in a fire. She is afraid it'll never hatch, and Laena reminds her that some never do, but that doesn't mean she'll never ride one. While Laena didn't bond with Vhagar initially, they clicked, later on, something that may happen with Rhaena. Laena is more involved with their daughters, and we get a brief look at her relationship with Daemon, which isn't all that strong. They have different ideas about what the future holds for their family.
At a meeting of the Small Council, they discuss a dispute between two lords over land. Rhaenyra and Alicent find themselves on opposite sides of the discussion, with Lyonel agreeing with Rhaenyra, something Alicent scoffs at.
They argue over how to defend the Stepstones. Alicent argues that the cost of protecting the area might be too great, and Rhaenyra says that a war would be even costlier. To heal the rift between them, Rhaenyra proposes a marriage between Jace and Alicent's daughter, Helaena. In addition, if Syrax gives birth to more eggs, then her son, Aemond, will have his pick.
Alicent informs Rhaenyra that she is accidentally lactating, bringing the meeting to a halt, and Alicent says they will consider the offer. As Alicent and Viserys walk back to their chambers, she tells him they can go forward with that proposal when she is dead.
It seems pretty clear that she doesn't want to accept Rhaenyra's offer.
Lyonel meets with Viserys and Alicent and tells them that he believes he should resign his position as Hand of the King due to Harwin's alleged transgressions. Viserys doesn't accept his resignation, saying he is perhaps the best Hand he has ever had.
He asks for time away from the Court to take Harwin back to Harrenhall, as Harwin has been expelled from the City Watch for the incident with Criston. Viserys accepts, and a frustrated Alicent leaves and has dinner with Larys Strong.
For the past few years, Larys has been Alicent's eyes and ears around King's Landing. She tells him that Lyonel is escorting Harwin back to Harrenhall, and Alicent wishes her father were still in Court to help her in these affairs. Despite having a slimy guy like Larys in her corner, she claims to have no one on her side.
Larys visits the King's Landing dungeons and recruits some of the worst prisoners there (a murderer, a deviant, a traitor, you get the idea) for a mission. To ensure their silence, he has their tongues ripped out.
In Pentos, Laena is struggling to give birth, much like Queen Aemma did in the first episode. The doctor tells Daemon that there's no more he can do, and the baby will not come out. He's given the same choice that Viserys was, but before he answers, Laena rises from her bed and goes to Vhagar.
To die a Dragonrider's death, she commands Vhagar to breathe fire, which the dragon reluctantly does and kills her. Daemon rushed to stop her but arrived too late and was forced to watch her be engulfed in flames.
Before leaving King's Landing, Harwin says goodbye to his sons. Jayce realizes that he is his birth father as Harwin departs. He asks if he is a bastard, and Rhaenyra says that he is a Targaryen and that is all that matters.
Rhaenyra, fed up with the scheming and politics, wants to leave King's Landing and move the family to Dragonstone.
The Strongs arrive at Harrenhall, as the men that Larys recruited watch on from a distance. As Lyonel sleeps, smoke begins creeping into his room, and Harwin tries to get out of it as it is engulfed in flames before the roof collapses and kills them both.
As Rhaenyra and the family get to Dragonstone, we get a voiceover from Larys, describing how children may be the end of everyone seeking power. Saying that people surrender what they shouldn't to protect their kids, love stays the hand.
We see that the voiceover from Larys was him telling Alicent what had transpired and that he was responsible for the deaths of his father and brother. Alicent expresses disdain for this, saying she didn't want them to die. However, now that the Hand of the King position is open again, her father may return to the post. She is now involved, and he will be rewarded by her when the time is right.
