Why is Alicent going to Harrenhal
I have a theory about why Alicent is going to Harrenhal.
Alicent made a deal with Rhaenyra for herself, Helaena, and her daughter. Rhaenyra had promised them safety. But at the time of the deal, Alicent did not know about Helaena’ pregnancy and that she would have a boy. The High Septon will refuse to crown Rhaenyra until there is proof of Aegon's death. Rhaenyra is not going to spare even Daeron and wants to send him to the wall because he is a pretender to the throne. And then Aegon's son, the heir, is born. In the leaks about Maelor, it is clear that the child is not being held by maids or nannies, as is the case normally, but by Rhaenyra’ royal guard. I don't think she'll order the child to be killed, but she probably won't let Helaena and Alicent raise him. Most likely, she will take him away to be raised under her supervision, and then she will probably send him to the wall like Daeron. And then, perhaps, Alicent will remember about Aemond. We know she's going to Harrenhal on some kind of mission. But her real goal may be to convince Aemond to kill Damon in order to save Alicent, Helaena and the children. It doesn't look like he's burning Riverlands in the middle of the season, he's probably just at Harrenhal with Alys. And it takes some kind of catalyst for him to start doing it, to lure Daemon out. In the last conversation, Alicent tells Aemond that she will come to Harrenhal to see him. Moreover, she tells him that he needs to lure Daemon out and kill him, this will be a very serious blow for Rhaenyra, from which she will not recover. Maybe she was just talking nonsense so that he would fly away, but it would be funny if all this actually happened. By the way, that's exactly what Aemond said in the book, and that was his plan. Maybe Helaena will contact him, too.
In addition, Ewan said in his interviews that Aemond wants to win the war for his mother. And I remember a song that Gayle posted about a year ago, where the hero prefers family to a girl, even though the girl loved him more. Maybe all this doesn't mean anything, but it seems to me that Aemond’ story will somehow be connected with Alicent.
