I’m honestly surprised that the show made this callback

Interesting.

@Copper Knight  
Found it

@Copper Knight  
Yeah, I’ve seen a video about this situation some time ago, it besically saids that the more distent the family is, the less incest it’ll be.

@Copper Knight  
Good point.

@sTs  
Technically speaking it was around 8 generations ago. That is super, super removed and you wouldn’t share any blood by that point.

@sTs  
Yeah. It seemed to imply they weren’t related.
 
Unless it did and Hasbro dropped the idea…
 
If so, ApplePie anyone?

@TheMultiBrony21  
Do you remember that other episode, where pinkie pie and applejack could be cousins?

@sTs  
That is likely not true.
 
Marble and Big Mac showed interest in each other in the episode they met.

Are you guys not aware that big Mac and marble pie could somehow be related?

@Copper Knight  
The staff loves to do Hearth’s Warming episodes (can’t blame them, I’m a huge fan of Christmas). Creating headcanons is a good way to avoid confusion!

@Background Pony #2B76  
Well, it’s just that Sugar Belle and Big Mac didn’t get together until season 7 and season 6 had a Hearthswarming Episode. And then we had another in season 8 too.

Tough luck for her.

start a harem!

@Copper Knight  
About how many times passed since that one… I like the way you think! I headcanon Best Gift Ever is Twilight’s fifth Hearth’s Warming since she and her friends defeated Nightmare Moon. Anyway, Marble needs to move on!

@Background Pony #7B4F  

 
Meh, if you want a friend forever and you’re truly good of heart, why not? ^^

Funny

Well, she should have tried to win him over. It was a year before he got with Sugar Belle and it’s been three since that one Heartswarming. She couldn’t have expected him to wait and stay single…

 
LIES AND SLANDER

@Background Pony #7B4F  
You say that like it’s a problem.

@Autumn_Shy
 
Pinkie for an inlaw. Think about that…

@Autumn_Shy  
Good point. ^^
 
(I know a few though.)

@TheMultiBrony21  
What brony wouldn’t? ^^

One day she will find her special somepony.  
And so will Limestone.

I hope the show will resolve this plot issue in Season Nine.
