House of the Dragon Season 3 finale has five obvious fires to put out, although this family’s preferred method involves pouring dragon fuel over each one. The season opened with the Battle of the Gullet and Jacaerys’ death, after which Rhaenyra seized King’s Landing, executed Otto, and began treating her claim as a sacred mission. Emma D’Arcy described that shift to Entertainment Weekly as Rhaenyra believing she has a “divine mandate to rule,” which explains why disagreement now looks like treason from where she sits.

Criston died at the Butcher’s Ball on Episode 6, while House of the Dragon Season 3 Episode 7 left Corlys in Ormund’s custody, Alicent fleeing Harrenhal, Helaena dreaming of Dreamfyre, Sunfyre returning to Aegon, and Ulf considering an offer to betray Rhaenyra for Driftmark. Director Nina Lopez-Corrado even advised book readers to refresh their memories about Tumbleton, so subtlety has packed its bags and left Westeros. These predictions rank the finale’s likeliest developments from a dangerous political choice to the betrayal that could scorch an entire town.

5Corlys’ Capture Forces Alyn to Pick a Side

Corlys’ mutilation cannot remain another unpleasant letter on Rhaenyra’s desk. Ormund has taken the Lord of the Tides prisoner, removed one of his fingers, and offered Driftmark to Ulf as though Velaryon land were a tavern prize. That insult places Alyn in a position he has spent the season resisting: he may need to defend the father whose name and affection arrived years too late.

The Gullet already pushed Alyn and Corlys into open conflict, with actor Abubakar Salim describing the naval battle as both catastrophic and bound to their troubled family relationship (via Entertainment Weekly). A rescue attempt would give Alyn a choice grounded in character rather than bloodline. He can save Corlys without forgiving him, and I would prefer that thornier route over an instant father-son reconciliation.

In Fire & Blood, Corlys remains one of Rhaenyra’s senior advisers until their alliance fractures over Addam Velaryon. The show has moved pieces around, so his captivity may replace part of that political rupture. My prediction is that Alyn takes command of the Velaryon response while Baela refuses to surrender Driftmark to Ormund’s bargain-bin lord.

4Helaena’s Vision Warns of the Dragonpit

Helaena’s Dreamfyre vision probably will not end with her charging into Tumbleton like a surprise cavalry unit. It looks more like a warning about the Dragonpit and the violence waiting inside King’s Landing. Episode 7 places Helaena on Dreamfyre as an army of smallfolk advances, and Lopez-Corrado explained that Helaena views dragons as forces that corrupt people and reshape the world around them. That fear matches Fire & Blood, where Dreamfyre remains chained in the Dragonpit until a furious mob storms it. She kills more attackers than the other trapped dragons combined before crashing into the dome, which buries her beneath stone (via A Wiki of Ice and Fire).

The finale may connect Helaena’s eclipse, snow, and approaching crowd to Rhaenyra’s deteriorating rule. I expect another vision rather than the full Dragonpit disaster, since the show still has an entire final season to fill. Even so, Helaena may understand that taking King’s Landing has placed her dragon, children, and the city’s people on borrowed time. Rhaenyra grabbing Helaena for answers was also a rotten move, and I hope the finale lets Helaena refuse to become the queen’s personal prophecy dispenser.

3Alicent Delivers Aemond’s Location to Rhaenyra

Alicent escaped Harrenhal after drugging Aemond and learning that he had tried to kill Aegon. She now carries confirmation that Rhaenyra wanted, along with the knowledge that Alys has tied herself to Aemond’s ambitions. The season began with Alicent and Rhaenyra attempting a pact that neither woman could fully trust. D’Arcy told TVLine that their history makes trust difficult, and seven episodes of executions, secrets, and endangered children have not improved the arrangement.

My prediction is that Alicent returns with Aemond’s location, but she asks Rhaenyra to spare him or capture him alive. Rhaenyra will refuse, which could finally kill their fragile pact. In Martin’s history, Daemon waits at Harrenhal for Aemond before their fatal confrontation above the Gods Eye. The show has delayed that collision and placed Alys more firmly beside Aemond, so Episode 8 may end with Daemon learning where his nephew is rather than fighting him immediately.

2Aegon and Sunfyre Turn Toward Dragonstone

Sunfyre’s return gives Aegon an escape route, a weapon, and something resembling confidence after an entire season of pain and humiliation. Lopez-Corrado connected the dragon’s recovery to the mythic bond between Targaryens and their mounts, while Fire & Blood records that Sunfyre survived Rook’s Rest despite being unable to fly for a period (via Entertainment Weekly).

The book path eventually takes both rider and dragon to Dragonstone. Aegon hides there, gathers supporters, and captures Rhaenyra’s ancestral seat before she realises it has fallen. Sunfyre later fights Baela and Moondancer, suffers further injuries, and becomes the dragon Aegon uses to execute Rhaenyra. The finale probably will not race through all of that, since doing so would cram half a season into one hour. I expect Aegon to abandon Braavos and choose Dragonstone as his destination. That decision would give Season 4 a loaded trap waiting beneath Rhaenyra’s supposed refuge.

Aegon has been down and out, but Sunfyre’s arrival puts him back in the game with a dragon-shaped chip on his shoulder.

1Ulf Betrays Rhaenyra at Tumbleton

Ulf’s betrayal is the safest prediction because the show practically handed us a map, a torch, and written directions. Ormund offers Ulf Driftmark and the title of Lord of the Tides after recognising how much he resents Daemon’s public punishment and Rhaenyra’s restrictions. Lopez-Corrado confirmed that the exchange leads into Episode 8 and directly told readers to revisit the Battle of Tumbleton (via Entertainment Weekly). In Fire & Blood, Ulf and Hugh arrive as Rhaenyra’s defenders before turning Silverwing and Vermithor against Tumbleton. Their treachery changes an apparent Black victory into a massacre, earning them the name “Two Betrayers.” (A Wiki of Ice and Fire)

House of the Dragon Season 3 may split their decisions. Ulf has already swallowed Ormund’s bait, while Hugh has received no comparable offer. I predict Ulf defects during the finale, but Hugh either hesitates or remains loyal long enough to make their eventual partnership messier. That change would suit the adaptation. Ulf betraying Rhaenyra for wounded pride is believable; Hugh following him without further pressure would be a harder pill to swallow. Episode 8 may end with Silverwing burning Rhaenyra’s soldiers while everyone realises that handing enormous dragons to resentful strangers was a fairly dodgy recruitment policy.

My money remains on Tumbleton as the finale’s main calamity. Corlys’ captivity, Alicent’s information, Helaena’s dream, and Aegon’s comeback can all point toward Season 4, but Ulf needs to make his choice now. The season has spent too long setting the fuse to end with another council meeting and a meaningful stare across a table. Will Ulf become the finale’s biggest traitor, or is Sunfyre about to steal another episode from under everyone’s noses?
