Alicent Hightower appears with her father, Ser Otto Hightower, the Hand of the King.
Alicent is described as "the most comely woman in the Seven Kingdoms." She was raised in the Red Keep and "possesses both a courtly grace and a keen political acumen."
According to HBO, Otto "loyally and faithfully serves both his king and his realm. As the Hand sees it, the greatest threat to the realm is the king's brother," Prince Daemon Targaryen, played by Matt Smith, "and his position as heir to the throne."
