Long time followers of fandom drama will remember that during the hiatus between Season 2 and Season 3, "Princess Skyla" was rumored to be the foal offspring of Shining Armor and Cadance. A clever /mlp/ anon cleared up the confusion that some other anons had with this recent news, as well as predicting the future:
Hey, maybe don't put your daughter as a self-insert into the show then?
We can only wonder what race/gender the new foal will be,
though we all know it's gonna be a fifth female alicorn considering that Cadance was born a pegasus in the books McCarthy now takes as canon, but who knows. All we know is that it's gonna start shit.
