What Gayle Rankin said about Alys Rivers Season 4
Rankin spoke to The Direct and confirmed she will be involved in the shoot for the fourth and final season. She was careful not to reveal details, but she explained why her return is natural: both Alys and Aemond Targaryen are “still alive” at the end of Season 3, as mxdwn reported.
On timing, Rankin said filming is expected to begin “early next year,” according to Wiki of Thrones. Winter is Coming noted that this lines up with comments from showrunner Ryan Condal and from Alicent actress Olivia Cooke, which means House of the Dragon remains on schedule.

Why Alys Rivers has unfinished business with Aemond
The Alys Rivers Season 4 story picks up from a Season 3 plot that Wikipedia’s episode summary describes in detail. At Harrenhal, Addam, Hugh, and Ulf wait to ambush Aemond, but Alys urges them to leave. Aemond then reaches Harrenhal on Vhagar, kills Simon Strong, and is injured. He begs Alys for help.
When Criston and Gwayne arrive, Alys claims Aemond is gone. She then helps him recover in the castle. mxdwn notes that Season 3 concluded with Aemond and Alys as lovers, which is why Rankin’s comment about them being alive matters so much.
Alys also has history with Daemon. In Season 2, Wikipedia’s summary notes she foretold his death at Harrenhal. That prophecy, her bond with Aemond, and the castle’s dark reputation all give the character threads that remain open.

The filming timeline for Season 4
Rankin’s “early next year” is the third cast or crew comment pointing to the same window. Condal said around July that Season 4 had essentially been written already, and that HBO would have all the drafts over the summer. Production would not start until early 2027, he explained, because the schedule is a complicated puzzle:
“Because the schedule is such a Jenga tower.” — Ryan Condal, on the Scriptnotes podcast, as reported by Inverse
A few weeks later, Olivia Cooke said filming starts “next spring,” according to Winter is Coming. Wiki of Thrones also reported in August that pre-production and set construction at Warner Bros. Studios Leavesden begin in October 2026, with principal photography with the full cast expected in early 2027.
Put together, the Alys Rivers Season 4 shoot appears to be targeting the first half of 2027.
What to expect from Alys Rivers Season 4
Nothing about Alys Rivers’ Season 4 story is confirmed, and Rankin gave little away. mxdwn argues that fans should expect more of her, noting that Alys has quite a bit more to do in the books. That is an outlet’s reading, not an announcement.
What we can say is that the setup is strong. Alys is one of the few characters connected to both Aemond and Daemon, and she controls what the other characters know about Harrenhal. The Alys Rivers Season 4 storyline will likely revolve around those relationships, though the show has changed many details from the source material before.
Rankin herself is a Scottish actress who joined the show in its second season. Wikipedia lists her as a main cast member with 12 episodes so far, and she is also known for GLOW.
When the final season arrives
HBO has set the final season for 2028, and Inverse points to summer 2028 as the most likely window. Season 3 aired from June 21 to August 9, 2026, and the show has typically returned within two years of the previous season.
That leaves a long wait, but the production updates from Condal, Cooke, and Rankin suggest the schedule is holding. For Rankin’s original comments, Winter is Coming’s report has the full context.
