I think you're right, but it doesn't make a difference to me either way tbh.
But the 2 queens trying to avoid war is part of my irritation with them trying to paint everyone grey. They should've just had Rhae saying, fukk all that, call the banners, and not used the shoddy 'misunderstanding' trope for Alicent to push the coup. It would've been better if Aemond and Luke weren't both yelling "no dragon, no!" at the same time during the biggest moment in the entire season so far. They could have at least had Aemond saying "oh well" with a smirk or something at the end. Dude just ran down a little kid on his giant murder lizard and we're supposed to think he was like "Oh no, I accidently killed him with my giant dragon! Whoops!"
It just frustrates me that everything is laid out as a 'series of unfortunate events' that characters get roped into, instead of people just being decisively shytty or good. Otto and Daemon seem to be the only ones who stick to their guns.
It wasn't a misunderstanding. Alicent is literally taking it as the king's dying wish to install Aegon as king. But also remember, an Rhaenys explained this to Alicent. Women are NOT empowered to be decision makers in Westeros. As she said "why don't YOU want the throne, why give it to your ain't shyt son?"
Alicent and to a certain extent Rhaneyra are all subject to the wills of MEN. So when Alicent thinks that the king wants his SON to follow him...she runs with it. When Rhae dares to show restraint, in opposition to her uncle/husband, she gets hemmed up for it. AND SHE A QUEEN.
Also, the foreshadowing of Dragons being not truly controllable has been set up. Besides that, remember that all of the kids are basically teenagers besides Aegon. If you've never had a tiff with your siblings and cousins then i don't know what to tell you. But that's in line with how immature people behave. Not to mention everything about Aemond says he has a mean streak, but he's NEVER been positioned as a kinslayer. He even still refers to Jace and Luke as "nephew". Dude is salty about his eye, but he's never been portrayed as a pure evil man. Hell if anything Daemon is more diabolical than Aemond has ever been.
Lastly, that IS how most things happen with war and history. It's very rarely some carefully intricate plot. Most times, its a sole actor jumping up and doing something without understanding the consequences. Otto and Daemon can be that way because they have DECADES of political/war experience. You see that in the past two episodes. While everyone else is freaking out, Daemon instantly goes into general mode and Otto starts politiking. That's what natural leaders do. Doesn't mean they are always correct but that is what they do.
