Instead of being a symbolic prize for King Viserys' eldest son, the regal stag walks up to Princess Rhaenyra Targaryen, which carries even more weight.

House of the Dragon episode 3 begins three years after the conclusion of episode 2, with unseen events such as Viserys and Alicent marrying, Alicent giving birth to Prince Aegon, Alicent becoming pregnant again, and Daemon and Corlys fighting a losing war in the Stepstones.

High lords and ladies from across the realm gather in King's Landing to celebrate Prince Aegon Targaryen's second nameday, which includes a feast and a celebratory hunt. While Viserys would rather drink and hunt, he is constantly confronted with the one topic he despises: his succession.

The white stag is a symbol of a quest for wisdom or glory in the stories of King Arthur and is said to be impossible to catch. It can also represent purity, otherworldliness, and prophecies—themes frequently connected to House Targaryen from Game of Thrones.
