The second episode of House of the Dragon saw House Targaryen further divided, as Prince Daemon broke off on his own (after Rhaenyra was named heir to the Iron Throne), stealing a dragon egg on his way out the door. A conflict arose later when it was revealed that the egg Daemon stole was the one selected to place in the crib of Baelon, Viserys' son who died shortly after birth. That egg was important to Viserys, but it could also be important to the overall Game of Thrones lore, as well as another Targaryen we're all very familiar with.
