Yeah, as of “Rainbow Rocks” and “Slice of Life”, I think that ship may have sailed.
 
Pun not intended (for once).

Nope.

@DrNazus  
Precisely! Well, either that or everyone, and I mean EVERYONE, is adopted.

@Scrounge  
I think we can safely say that genetics don’t work for them exactly the same as it does for us.

Seriusly, though, it took this picture to make me realize how many families in Equestria look nothing like each other whatsoever. Pinkie looks nothing like the rest of her family, the Cake twins don’t look like either of their parents, and don’t even get me started on the Apples. And that’s barely scratching the surface. Sweetie Belle and Rarity kind of look alike, but they seem to be the exception rather than the rule.

Lyra-Bon Bon  
Aloe-Lotus  
Flitter-Cloudchaser  
eh works the same for me…

…I don’t see a family resemblance, but I’ll admit that I wouldn’t have guessed that Pinkie and Maud were sisters if I hadn’t been told.

We always need a little rationality to stabilize the madness that is a fandoms interpretations.

@Arne  
To tell the truth, yes. It was already freaky enough with Twilight being paired with Shining Armor, and Apple Jack paired with Big Macintosh. Lyra and Bon Bon are either siblings or just best friends. Besides, they’re background ponies, We barely know anything about the way they interact with each other in the show. And out of all background ponies who got attention, Derpy got the most, but she only spoke in 2 episodes. Face it people, No matter how many “theories” are made based on characters such as Lyra, Bon Bon, Derpy Hooves/Ditzy Doo, Doctor Whooves/Time Turner, Vinyl Scratch, and Octavia, THEY’RE ALL MOST LIKELY FALSE!!! And as much as I wish for a side story that focuses on them, there is a very slim chance that there will ever be an MLP episode that focuses more on the famous background characters like in the IDW comics.

It’s kinda true. Pegasisters and pegacest are both practically synonyms for “Flitter and Cloudchaser.”

@SRD639  
I am. Are you honestly going to say that people wouldn’t ship it more due to the addition of incest?

@Background Pony #B857  
I meant your brains! Your minds! your thoughts! I didn’t mean that type of head!

@SRD639  
But dicks have heads too.

Seriously? ( _*)
 

 
Really guys… can’t you use your heads instead of your dicks to think for once?

Then we get a bunch of hot incest art.

I could get behind that… though my idea that Bonbon might be related to Twist would mean … oh god Lyra would be related to Twist too
 
shuddering

Well even if it’s incest… who cares, really?

INCEST! I love it!

Then people would ship you two even harder.

That makes some of the artwork I’ve seen of those two pretty awkward.
 
_{But also a bit hotter.}

Hot
