Wow. That makes it more confusing lol Someone pointed out that Luster Dawn would know about the mane six and them still being friends despite the separation (or at least partial because it seems like Rainbow Dash, Applejack and maybe Pinkie still live in Ponyville) if she were the spawn of Glim and Sunny Boy. I mean, wouldn’t Starlight tell her daughter. I’m sorry, I really, REALLY like the idea of her being their daughter but I feel there’s a few big things that make it a little hard to believe.
Actually now that I think about it, maybe Starlight tried to show/convince her to go for the Friendship school and that friends are the way to go but Luster just wouldn’t budge. And Starlight just gave her room instead of being pushy and let her do what she wanted, hoping she’ll learn one day. Especially since Twilight would be her teacher…….You know what this could work with some careful handling. Whelp, I changed my mind! My only issue is that raising a kid while being full time school runners is probably not the best idea. It much to juggle, you know. Though that can play into Luster not thinking about that school if she’s been around it a lot growing up and not seeing the big picture due to being desensitized/jaded with it as a result.
TL;DR I can actually see Luster Dawn being Starlight and Sunburst’s kid now lol
