The time leap in House of The Dragon:
In the first two episodes of House of The Dragon, the friendship between Rhaenyra Targaryen (Milly Alcock) and Alicent Hightower (Miley Carey) was established. After King Viserys I Targaryen's wife's (Paddy Considine) death, he is expected to take another wife, hoping she can bear a boy to ensure an heir for the Iron Throne. However, Viserys named Rhaenyra as the heir to the Iron Throne, breaking the tradition and angering his brother Daemon Targaryen (Matt Smith).
Viserys then declared that he would marry Alicent Hightower, which immediately caused Rhaenyra to become very distraught. Not only is Alicent now a threat to her grabbing the Iron Throne, but Rhaenyra also seems resentful about her friend wooing her father. Now, as the war for the Iron Throne will centre on family turmoil, House of The Dragon will take a 10-year time leap.
