#a selfish impulse that ultimately leads to his brother's injury bringing Aemond immense guilt

[sylvancastor]

Writing out my preferred way the battle at Rook's Rest should have gone because why not.

The beginning mostly stays the same. Criston signals for Aemond and Vhagar, but Sunfyre arrives first. Aemond sees him fly overhead and is pissed, but he doesn't wait to follow him into battle because he's not an idiot and as much as he wants the crown, he's aware of the intensity of the blow losing Aegon would be to their cause.

Still, Vhagar is slow and has to launch herself off the ground, so Aegon gets their first and has an initial fight with Meleys but Vhagar's quick arrival keeps Sunfyre's injuries from being quite so intense. The two of them attack Meleys side by side, but due to her speed and Rhaenys's expertise, she manages to keep evading them with fairly light damage.

Meleys takes off high into the clouds and Aemond and Aegon follow her. No one can see them from below. Aegon urges Sunfyre to engage directly with Meleys and the two dragons become locked together. Instead of intervening this time, Aemond simply watches as Sunfyre is injured and Aegon cries out for his help. Aemond only watches.

We can see the anger in his eyes. It would be so easy to allow Meleys to kill Aegon and Sunfyre. He could say he did his best, but that Aegon refused to battle carefully. He would be honored after he died and Aemond would become king. Aegon doesn't notice the inaction, too focused on saving Sunfyre and himself. In a desperate move, Aegon unclips one of his restraints to grab the dagger at his side and drives it into Meleys's eye as Rhaenys screams in shock and fury.

Meleys wails and lets go of Sunfyre, dropping out of view. Aegon is triumphant and turns to his brother with a smile. Aemond isn't smiling. We watch as he follows Meleys's descent and decides he's safe for now. He returns his attention to Aegon. It would be so easy to do the deed himself and blame Meleys. He contemplates it only for a split second, but Aegon's face goes from smiling to horror. We think he's understood what Aemond plans to do, but in fact, his eyes are fixed on a sight behind him. Meleys has darted up from behind, mouth open and poised to burn Aemond in his saddle.

Aegon doesn't hesitate. He urges Sunfyre forward and as Meleys breathes out a wall of fire, he throws himself and Sunfyre in front of it to protect Aemond from the blast. Before Aemond can react, Meleys sinks her claws into Sunfyre's chest and pulls him out of sight.

Aemond pursues, but it's too late. Meleys has bit into Sunfyre's wing and Aegon can barely stay in the saddle with his one remaining restraint. Meleys rips her head back breaking off part of Sunfyre's wing and the king and his dragon fall through the air, landing in the forest.

Similarly to the show, Aemond is able to defeat Rhaenys and Meleys on his own after Aegon's fall.

Later on, we learn the only reason Aegon was able to survive was the one remaining restraint held him to the saddle but allowed him to slide off to the side enough to evade some of the dragonfire. He's still burned and in pain. He sacrificed himself for his brother and Aemond can't betray him now. Not when he owes his brother a life debt, not when he's seen how deeply Aegon loves him. He becomes Prince Regent and reconciles himself to forever protecting his brother from this point forward.
