“Aunty Luna?” Is this about this “Celestia’s Spike’s mother” nonsense?
 
None of Lauren’s ideas like “Celestia raising Spike” were meant to be considered canon, ever.
 
Lauren hasn’t said that “Celestia is Spike’s mother” when she only mentioned Celestia just raising him. Once Twilight grew older, she took over. Twilight’s parents could’ve been the ones who raised him since his birth, as well.
 
It doesn’t make anyone a “mother/father,” nor having “motherly/fatherly” moments, acts… when she/he is just looking after or raising someone.
 
Anyone like Celestia or Luna, who’s a beautiful and powerful alicorn, doesn’t fit as a “mother” or “aunt” for a small, goofy, and clumsy character like Spike.
 
“Adoption” isn’t a must-thing. What’s only most important is that you take care of whoever you’re looking after.
 
It’s stupid and ain’t worth imagining this kind of stuff because it’s just “cute,” nor if it’s all only about Spike himself, at all. Celestia/Luna is only USED.
 
It’s impossible, and no point in having Spike in the show. Lauren wouldn’t say that Spike was “just left on someone’s doorstep,” that his parents “just abandoned him,” that his parents “just died…”

Just throw the CMC into one of his dreams. More then enough punishment.
 
NSFW || Or even better, this. That’ll scar a guy for life. >_> ||

I love his strut in the last panel. Spike is about to dish out some dream justice.

It probably says something about me that my first assumption was that that was Rarity’s dream.

I don’t know whether it would be better or worse if that was even his own dream.

I need this to be a thing now.

Okay, that got a chuckle outta me.
