GRRM added these random fucks for a reason.
yeah, as filler for the 5 years of downtime corner he painted himself into. they are ultimately meaningless
Aegon will show up in the show, otherwise if he doesn't then it will just confirm he's a non factor in the books. They are set on putting major plot lines from the books, more than the holding back and cutting major stuff out. Ya I know Stoneheart isn't in the show, but that's just filler in the book.
no way in hell aegon shows up in the show. There's only going to be 15 more episodes of the series. Not only has the show confirmed that he's a non-factor by not including him, the books confirmed that he was a last minute retcon by grrm to fill space while we waited on peoples training montages to complete.
Go back and read chapter 32 from A Game of Thrones, the one where Arya's chasing cats through the red keep and ends up in the hidden tunnels underground. She overhears the people talking, but as an 8 year old girl she doesn't understand it nor can she explain it to her father, but you as the reader know that Ilyrio and Varys' entire grand scheme is laid out. It was always Viserys takes the throne by way of dany's marriage to khal drogo. The speech varys gives at the end of book 5 is a continuity error on GRRMs part when he retconned the character in to fill pages and pass the time.
The only thing that matters is the realm is proper fucked so dany's conquest is easy, easy enough that she's got enough forces left to rally the survivors and fight the ww.
edit: The above quote further illustrates my point. They've been training "aegon" since birth to rule, clearly he would be their ideal candidate for the throne. but 'originally' post book 5 filler retcon, the plan was for Viserys (unquestionably the rightful heir of the last targ king) + 50k dothraki to somehow team up with Aegon (allegedly the true heir) + 10k golden company, and together they would conquer westeros? And then what? Get gay married? Oh but then he died, so then you have Dany + baby dragons and no support, who can then marry aegon + golden company, and together reclaim westeros, but she said fuck it and built a massive army and started sacking cities and doesn't even need the golden company any longer....so now just wait on her and her massive army and dragons to come along, and you can hitch a ride with her. Oh and then try to woo her and if you are lucky she will let you marry her and become king, otherwise if you try any shit you'll just get eaten by her dragons or else get kicked to the curb.
as much shit we give the show writers, grrm's last few books on which they are somewhat based are equally just as shit. Just like the dorne storyline that also tried to retcon some secret master plan, which was 100% full retard.
