In addition to his usual cunning intentions, Otto Hightower (Rhys Ifans) predicts House of the Dragon's future with a startling degree of accuracy.

Otto was introduced as a prominent opponent in the first season of House of the Dragon, and Viserys eventually fired him from his position as Hand of the King as a result of his well-planned schemes.

Despite demonstrating his extreme unreliability by compelling his adolescent daughter to seduce the King and adamantly defending his grandson Aegon's claim to Rhaenyra,

In the fifth episode of House of the Dragon, Otto is halted as he leaves King's Landing by his daughter Alicent, who laments that her activities led to his dismissal.

Otto cautions Alicent that standing up for Rhaenyra was foolish and that doing so is only delaying the steps that must be performed to install Aegon on the Iron Throne.

Otto Hightower will be one of the leading proponents of putting Aegon on the Iron Throne, along with Alicent and Criston Cole.

With several Great Houses already revealing their true selves in House of the Dragon episode 3's search for the white stag, being fired as the Hand of the King now allows him plenty of time to gather additional Great Houses to Aegon's cause.

After House of the Dragon episode 5, suspicion about Rhaenyra's private life persisted, giving Otto more justification to damage her reputation in favour of Aegon.

This does not alter the reality that Otto's scheme is an outright takeover of the Iron Throne from the legitimate heir, and that this treason has only grown more perilous since Viserys revealed the significance of Aegon's prophesy to Rhaenyra.
