House of the Dragon can't get enough of a good prophecy.

We've already had a number of these courtesy of Helaena (Phia Saban), but there's one big central prophecy that things keep coming back to. We're talking, of course, about the Song of Ice and Fire dream that Aegon the Conqueror himself had, and which Viserys (Paddy Considine) told young Rhaenyra (Milly Alcock) about back in the show's very first episode.

We're now a few seasons on from that moment, but the prophecy continues to hang over our central characters like a shadow. So, how did it rear its head in episode 3, and what does it mean? Let's recap.

How does the prophecy feature in Season 3, episode 2?

The prophecy is mentioned by Daemon (Matt Smith) when he returns to Dragonstone and finds adult Rhaenyra (Emma D'Arcy) bedbound with grief over the death of her son, Jace (Harry Collett).

"I saw it, Rhaenyra. At Harrenhal," he says. "The darkness in the North. The Song of Ice and Fire. I saw a girl with silver hair in a desert far away, and there were dragons at her breast."

He's talking specifically about the visions he had during his time at Harrenhal in Season 2, during which he saw images from the prophecy, along with glimpses of his own role in the story.

For a moment, Rhaenyra remains unmoved. But then Daemon says something that clearly gets through to her.

"But if it is real, what my brother told you... if it were true... what, then, would you do?"

What prophecy is Daemon talking about?

Hang on a minute. What did Daemon's brother Viserys tell Rhaenyra again, exactly?

Here's a reminder of his speech, word for word, from episode 1:

"Just as Daenys foresaw the end of Valyria, Aegon foresaw the end of the world of men. 'Tis to begin with a terrible winter, gusting out of the distant North. Aegon saw absolute darkness riding on those wings, and whatever dwells within will destroy the world of the living. When this great winter comes, Rhaenyra, all of Westeros must stand against it. And if the world of men is to survive, a Targaryen must be seated on the Iron Throne. A king or queen, strong enough to unite the realm against the cold and the dark. Aegon called his dream the Song of Ice and Fire. This secret has been passed from king to heir since Aegon's time. Now you must promise to carry it and protect it. Promise me, dear Rhaenyra. Promise me."

Looking back on that, it's not hard to see why Daemon's mention of the prophecy — and the fact he's seen it himself in a vision — is enough to persuade Rhaenyra to push on to King's Landing. Back in Season 2, she tells Jace about the prophecy in a way that suggests she has come to believe it. And given that she also believes her father wanted her to be his heir, it follows that she needs to return to King's Landing to carry out Viserys' wishes.

House of the Dragon Season 3 is now streaming on HBO Max, with new episodes every Sunday at 9 p.m. ET on HBO and HBO Max.
