well, no. but Celestia never raised spike, even as an egg. they just have those eggs incubated somewhere to give to students.
Then who raised him then? Twilight couldn't do it since she was too young.
who asks this many questions about a childrens' show?
I do.
And that's fine. When you like something, especially a fictional story, you should make discuss them thoroughly and create storyline theories. It strengthens the ran community to converse like that's together. It's what we do very often in the BIONICLE fandom at BZPowee.com Anyway, the idea that Celestia raised Spike after he was hatched by Twilight was just an idea Lauren Faust had. She suggested that the writers use it, but they ended up writing the story so that Twlight had raised him alone ever since she hatched him. She wven says it in an episode.
