For those who don't know what I'm talking about, The Prince of Egypt, is one of Dreamwork's first animated films, and it was an adaptation of Exodus. But the element that causes me to connect it to House of the Dragon is because unlike most adaptations of Exodus, this movie takes a more personal and emotional route. In this movie, the entire plot revolves around the fact that Moses and Pharoah, are adopted brothers. As such, before Moses becomes a Shepherd, we see him and his adopted brother Rameses, having a very good brotherly relationship.
But the problem is that Rameses lives in the shadow of his dominating and overbearing father who sees his son as "the weak link". And his desire to live up to his father's expectations, is what causes him to refuse to let the Hebrews go. So, Pharoah is portrayed as more tragic. We know why he's making his choices and how much is destroys him and Moses to declare war on each other.
I think Rhaenyra and Allicent are the same. Both once loved each other as sisters and the heart of the entire story revolves around that. But when Otto forced his daughter to marry Viserys, and both becam caught up in the intrigue and rivalries of politics and family, both became the very people they hated. But I can tell that deep down, this is breaking both of their hearts. And I won't be surprised if in both of their final scenes, they'll realize the monsters they have become, long for their "sister" and miss the woman they used to be. It'll be more tragic then that dinner scene.
