Well, yes. But I mean in canon it’s the most likely explanation.

For me Twilight has the Role of big Sis AND a Mom.Celestia and Luna are his Aunties

Spike, in all likelihood, was an orphan egg, left unhatched in a clutch that was abandoned. Otherwise, he wouldn’t have been there as an egg at all.

Is it weird that this made me think of when Inuyasha and Kagome finally kissed? That’s the music that comes to mind for this scene.

The fact that she hatched him at a young age doesn’t stop her from being mom. Sure, Velvet might help to take care of Spike, and I suspect Celestia had more than a hoof as well, but that makes them his Grammas, not his mom.

I don’t think the school in Canterlot has dormitories, they probably live at home and walk to school, like normal kids.

Twilight’s definitley a better big sister than a mom. I dunno about Velvet. Was Spike raised in the Sparkle household or celestia’s castle? I guess it depends where he grew up.

Wouldn’t Twilight Velvet be more like Spike’s mom and Twiggles be closer to his big sis?

She is the closest thing to a maternal figure he has but they’re so close to the same age it feels a bit weird for him to consider Twilight his mom. Big sister? That feel a lot closer to the mark.

But unlike Twilight, they were never there for him, and that makes Twilight his real family.

Eh, I prefered it when they were just friends. Spike did have parents after all (Otherwise, how would the fucking egg even come into existence…?)
