HOTD Season 2 has been a hit since the beginning, and with each episode it continues to grow in popularity. The anticipated Targaryen civil war began with the Battle of Rook's Rest, which ended with the deaths of Rhaenys and Meley. Aegon also suffered severe injuries after crash landing on the ground. While some fans thought it was an accident, several fans were confident enough to say that it was Aemond who tried to kill him. Everything was speculative until Haela's words hinted at Aemond in the season 2 finale. But how did she know that?

Yes, the Targaryen Queen Haelena knows that Aemond tried to kill her brother-husband Aegon. Well, she didn't see the whole ordeal with her own eyes, but she knew about it.

Haelena Targaryen was one such character of the universe created by George RR Martin, who was always sidelined due to her introverted personality. Since childhood, she was often seen either talking to insects or enjoying her own company. So it's obvious that no one paid attention to her prophetic abilities. She is a special character who in HOTD Season 1 foreshadowed some big events that really happened later in the series.

For example, when Aemond tells his mother Alicent that he needs to claim a dragon, Haelena predicts that he will surely get a dragon but not without losing an eye. I clearly remember what she sounded like back then. Her words were: "He must close an eye." After that, Haelena also prophesied about the civil war.
