Or is it?
Here is my logic:
Two southener siblings that live on the outskirts of the town.
Big Mac is like one of the only Stallions in Ponyville.
Applebloom has no parents we can decipher.
Call it what you want, I'm just posting the fact that I see.
Also, I'm a little bit of a sick f*ck, so that tends to get in the way of things.
