Back in episode two, and more than 13 years ago in the timeline of "House of the Dragon," King Viserys spoke with Lord Corlys Velaryon and Rhaenys about the turmoil that could plague Westeros if House Targaryen did not shore up its line of succession.
Viserys wanted to delay remarrying after Aemma's death, but Corlys told him that waiting any longer could be risky.
"To elude a storm, you can either sail into it, or around it," Corlys said. "But you must never await its coming."
All these years later, Corlys' son Laenor is now married to Rhaenyra — but she's been having children with Ser Harwin Strong, making her children "bastards" in the eyes of the realm and therefore invalid successors to the Iron Throne. More attention is being brought to this "rumor," leading to Rhaenyra's decision to leave King's Landing and take up residence in Dragonstone, the first home of Targaryens in Westeros.
"The wise sailor flees the storm as it gathers," Laenor told her before she made her choice.
But we'll have to wait for next week's episode to see how sage this advice really was. Can Rhaenyra really get around this storm? Or will she need to sail straight into it soon?
