Actually, Cadance has never been referred to as Celestia’s niece in the show, only in the side material.

@Cryosite  
You would think Twilight at least would know the difference between “exercise” and “exorcise”.

@Cryosite  
But the sirens aren’t in this image.

I think there has been a terrible misunderstanding here. This isn’t what we meant by, “exercise the demon.”

cadance is so happy!

@Yet_One_More_Idiot  
She did refer to her as her niece in ACW.

@Lord Seraph  
Isn’t Celly the aunt of Cady?
 
That would make her Flurry’s great-aunt, no in-law required. :)

Best grand aunt in law

omg this is precious <3

@Moon Flower  
Maybe they’re using their magic to bat the ball back and forth? Just without showing the magic aura. :)
 
Lulu sleeping and Twiley with büükface are the cutest things about this for me. :D

It’s a matter of seconds until that ball is no ball anymore. Pokey horns. :D

I think it is silly to assume that Sparkle would have no wings.  
Flurry Heart happened way after she got her wings.  
And as someone mentioned already, Cadence’s and Luna’s wings aren’t seen either.  
I guess they covered by their bodies or the blur of the background.

super cute!

@Background Pony #C9F4  
Nah, I’d say no. You can’t really see the wings clearly for Luna or Cadence either and I see no reason for the artist to go out of their way to do that for all three of these characters. If anything, it’s an accident at the most, and at the least, it’s just an angle thing.

Ambiguous Twilight?

While it’s not enough for me to change it, it would be weird on multiple levels if Twilight wasn’t an alicorn in this picture. Dunno.

Tagged with unicorn Twilight, are we sure on that? And also, her horn seems to be missing too.

It’s nice the youngest and oldest get to play together and just have fun

;3;

don’t head but the ball

Not afraid to say that everypony in this picture is really freakin’ cute.
