it’s an unserious name but a serious theory!!!
WHAT WE KNOW ABOUT QUENTYN BALL
If Daemon had ridden over Gwayne Corbray . . . if Fireball had not been slain on the eve of battle . .
-small mention from eustace in the sword sword
For his hot head and red hair. Ser Quentyn Ball was the master-at-arms at the Red Keep. He taught my father and my uncles how to fight. The Great Bastards too. King Aegon promised to raise him to the Kingsguard, so Fireball made his wife join the silent sisters, only by the time a place came open, King Aegon was dead and King Daeron named Ser Willam Wylde instead. My father says that it was Fireball as much as Bittersteel who convinced Daemon Blackfyre to claim the crown, and rescued him when Daeron sent the Kingsguard to arrest him. Later on, Fireball killed Lord Lefford at the gates of Lannisport and sent the Grey Lion running back to hide inside the Rock. At the crossing of the Mandel, he cut down the sons of Lady Penrose one by one. They say he spared the life of the youngest one as a kindness to his mother.
-egg says this in the mystery knight, bolded parts mine
Daemon was the name Daena gave to this child, for Prince Daemon had been the wonder and the terror of his age, and in later days that was seen as a warning of what the boy would become. Daemon Waters was his full name when he was born in 170 AC. At that time, Daena refused to name the father, but even then Aegon's involvement was suspected. Raised at the Red Keep, this handsome youth was given the instruction of the wisest maesters and the best masters-at-arms at court, including Ser Quentyn Ball, the fiery knight called Fireball. He loved nothing better than deeds of arms and excelled at them, and many saw in him a warrior who would one day be another Dragonknight.
The king sent the Kingsguard to arrest Daemon before he could take his plans for treason any further. Daemon was forewarned, and with the help of the famously hot-tempered knight Ser Quentyn Ball, called Fireball, he was able to escape the Red Keep safely. Daemon Blackfyre's allies used this attempted arrest as a cause for war, claiming that Daeron had acted against Daemon out of no more than baseless fear. Others still named him Daeron Falseborn, repeating the calumny that Aegon the Unworthy himself was said to have circulated in the later years of his reign: that he had been sired not by the king but by his brother, the Dragonknight.
-these are both from TWOIAF, again bolded and italicized parts mine.
Quentyn is married, a landless knight, and clearly older than Daena - it’s not just about a man “spoiling” a young, royal maiden but imo also that Quentyn specifically would get in a LOT of trouble because he is low class (see: Bonifer & Rhaella) and married to boot
He was master at arms, which gives him the ability to be in Daemon’s life without arousing suspicion from anyone, and also proximity to Daena to allow for an affair, even with her on the Maidenvault.
He’s name dropped SEVERAL times and he’s clearly very important to the founding of the Blackfyre Rebellion despite being both very lowborn and also dying in a kinda lame way (not even during the battle, just by a lone archer)
He wanted so badly to be on the kingsguard he forced his wife into the Silent Sisters, only to be denied by Daeron
He seemed to be on good terms with Aegon IV
Everyone seems real sure that the daddy was Aegon and we’re not given a reason why
Aegon doesn’t claim Daemon as his bastard until after (presumably) Daena has died
Also, Aegon doesn’t claim Daemon as his bastard until after all of the Great Bastards have been born
EYE think that Aegon IV was purposefully trying to have a bastard that could challenge Daeron, and that his affairs weren’t just like lust, boredom, wanting to disrespect Naerys & Aemon, etc. There is, imo, a shift in his mistresses being just, any woman he has access to - Falena, Bellegere, Cassella, and Meg - to woman who are highborn maidens from powerful families in Westeros - the Blackwoods, Brackens, and Lothstons. Even Serenei fits in here, given that Targ-looking wives from Lys & Volantis are not uncommon before or after Aegon IV. He’s even mentioned as still having a role in Aegor’s life by visiting him, potentially trying to groom him to rebel. But then everything with the Brackens blows up in his face (which is his own fault tbc), and Brynden is an emo fuck with red eyes, and Shiera is a girl. Then Daena dies…..and an opportunity opens up. Daemon looks like a Targaryen, no one knows who the father is, but for some reason everyone already suspects him (imo this is due to Rhaenyra’s boys looking like Harwin - like just a misogyny thing that SURELY Daemon couldn’t get his look from his mother alone, look at Rhaenyra’s kids vs Alicent’s), so publicly claiming Daena’s child at last gives him the perfect rival against Daeron.
ALSO, we have a few times in the story where someone joins the Kingsguard to be closer to a woman they want to protect - Aemon & Naerys, Jaime & Cersei, and Loras & Margaery. I think Lewyn & Elia likely fall under this as well. I think it makes sense Quentyn would see joining the Kingsguard as an opportunity to be closer to both Daena & Daemon especially given his low class status; skilled knights can rise to the Kingsguard even from lowborn or baseborn backgrounds. ALSO ALSO again, our only evidence of Aegon IV being the dad is, ya know, Aegon himself. Daena stayed silent her entire life on the subject. I like to think she had a reason for this - not that she protecting Aegon, but that she was protecting Quentyn.
