I donât think that Aemond Targaryen Actually died during the Battle over the Godâs eye.
In the show Aemond is shown to have a helm that buckles under Aemondâs chin that takes a moment to unbuckle & remove.
First of all the book states explicitly that there is only half a second between the time Daemon leaps from Caraxes, holding a sword in one hand, somehow lands on his feet without falling off despite having no free hands to hold on, because Daemon supposedly unbuckles Aemondâs helmet & despite having no hand holds &/nor tether on a free falling mass of fire lizard manages to not only stay astride Vhagar but also apply the precise force necessary to cut through a saphire the size of a ping pong ball with a sword.
While Aemond is also conscious, belted in & has amp,e opportunity to push Daemon off of Vhagar &/ or fight back.
Daemon is not especially athletic during the BOtGE either & is explicitly stated to barely be able to climb astride Caraxes.
I think none of this version of events from Fire & Blood sounds plausible.
These dragons are in free fall, with different Aerodynamics so itâs unlikely that theyâre maintaining the same positions relative to each other making clearing that jump implausible even for a young man like Aemond, least of all Daemon, due to the mobility of the target.
Furthermore Daemon makes the bizarre choice to take the time to remove Prince Aemondâs helm even though Aemondâs seeing eye would be easier to stab & way less of a time wasting hassle. Removing Aemondâs helmet just for Daemon to specifically give himself the task of trying to stab through a massive sapphire on a moving dragon, lodged inside a moving target seems completely nonsensical, nigh impossible & irrational. Itâs just too bizarre a thing to do given the constraints both temporal & physical of that situation.
Additionally since Daemon would be holding Dark Sister in one hand & fiddling with Aemondâs helmet & its buckle unnecessarily that leaves Daemon no way to hang on even if Daemon really did manage to land on Vhagar.
Nor could Daemon have defended himself against Aemondâs fists & any melee weapons Aemond brought up on Vhagar with him. Thereâs no way Daemon would have actually managed to stay on Vhagarâs back even with more time.
Furthermore, Rhaegarâs rubies were being hunted upon the trident fifteen years after Rhaegar died. But for some reason the divers who took the time to haul a dragon, a sword & a human skeleton up from the bottom of the Godâs Eye didnât bother recovering a sapphire the size of a large walnut, that beggars belief.
Plus Aemond has the cats paw dagger & we all know that makes it back to kingâs landing-as does Black Fyre which Aemond now wields as acting King. These two Valyrian steel nearly priceless heirlooms are never mentioned in the recovery process.
Daemonâs corpse also mysteriously vanished during BOtGE.
I donât think that itâs Aemond that died during the BOtGE, I think Daemon died & Alysmond needed some story to explain away why Aemondâs most prominent personal effects were missing. I think Aemond managed to get free of Vhagarâs saddle, I think Alysmond dumped Daemonâs body & Dark Sister with Vhagarâs remains.
Otherwise I think Daemon would have just been said to have killed Aemond & all these bizarre impossible mechanics wouldnât be brought into the story.
I think Aemond, now with a wife & child Aemond genuinely loves didnât want to marry the Baratheon girl & I think Alysmond & baby Alysmond all vanished within a couple years of each other & the family went to live somewhere safe in Essos.
I donât think Aemond was dead, I think Aemond was in Harrenhal with Alys & baby Alysmond the entire time the DotD was winding down. Alys somehow is keeping hundreds of dangerous criminals under Alysâs thrall with all these spontaneous acts of inexplicable violence. Especially all the strangling, thatâs Aemondâs move. Alys is stated explicitly to have to stop Aemond from, choking a page to death. Thereâs some bizarre dragon magic in Harrenhal that everybody who goes in there swears they saw. I think the only reason Alys & baby Alysmond & Aemond do t all disappear at once is to avoid arousing suspicion & starting yet another dispute over Aemondâs broken pact with the Baratheon daughter to marry the latter.
Aegon is terrified of Aemond-at least in the show, it seems way more like,y that Aemond is Aemonding & going hey Aegon build this monument & say Iâm dead or else then that Aegon just spontaneously had a change of heart after the injuries & Sunfyre dying.
I think it could be a metaphorical dragon the these criminals see in Harrenhal-maybe sensimg Aemond there. I think itâs kind of a green flag Aemond might have lived after all that anybody who laughs at Alys/doesnât believe Alys gets killed like, instantly & nobody ever sees how they died supposedly. Aemond is known to be touchy about being laughed at- a sensitivity one could easily reason would extend to Aemondâs wife & child.
I donât think that thereâs any other explanation that covers all the bizarre details that are weird about the BOtGE & its aftermath, as it were.
