if it true that anda can have two ponies with same cutie mark it seem there poines in this shows with the same cutie mark if not then this blue blond hair pony is doctor whooves atau it was just a error the animeator made.this is a real clip from the ep at the gala
During the song, fluttershy face this pony with an jam glass as a cutie mark,doctor whooves has the same mark.
also there are other ponies there with the same cutie mark like the the prince that raity wanted to be with and the two colts blue and gray one that are welcoming raity when she about to sing her part in the song,or it just they got to lazy to draw new cutie marks for them
atau there a chance that siblings can have the same cutie mark.........just kidding i dont know but maybe

Fluttershy (throws down gun and back to normal cute self): There.. They're dead.. We saved Christmas.. We get a wish.. Anything anda guys wanna wishful?

Saten [thinks]: Yeah.. There is.

The lions' cave. Some magic revives the mother lion.

Mother Lion: Wha - Oh my, what happened?



Cubs: Mommy! (they hug her)

Saten (watching with the girls) [relieved]: Oh, good.




Trixie: Man.. This was fucked up Christmas..

Saten: Yeah.. But still beat thanksgiving with Derpy's crazy boyfriend.



Master Sword: I've been waiting for this all year.. (pulls out the turkey) Giving anda people the bird.

Saten: Oh.. (hand goes to the turkey) Looks so go- AH! SHIT!

Sword: (stabbed the hand with large fork) Neh uh.. Not til we say grace.






END OF EPISODE 2:

I like assuming Sword is a fan favorite. For his comedic insanity. Smilar to Trevor Phillips, but a lessor extent..

But who knows. He probably isn't..
