AJ’s vector is likely from S06e15, “the Cart before the Ponies”

No thanks.

@Masem  
Yay! I bet Rara’s gonna come back! :D

@Masem  

 
Yup. I wonder what kind of vehicle they will be riding.

Never understood the attachment to this character; an apple crushing on AJ is better. However the transgender aspect of caramel/toffee makes their character tremendously more interesting.

 
Vegas confirmed by larson

@Mr. Horrible  
More like Applebloom’s.
 
@Background Pony #8391  
Or Flim and Flam had a hoof in it and we have an aesop about revenge.

Hobojack.

Revelation for this or future seasons:
 
Twilight will lose/sacrifice her wings
 
Pinkie Pie is NOT adopted, but turns out her mother ate some poison joke when she was pregnant.
 
Flim and Flam lost their parents in the same incident that Applejack lost hers.
 
Fluttershy is not her real  
name!  
But might as well be because there’s barely any difference.
 
Adventure time-style gender swapped episode with crystal mirror. Must include cameo by real Twilight at the end.
 
Twilight knew spike was gonna grow up one day, so after his first birthday she put a spell on him that slowed his aging. But she messed up, and now he’ll barely grow bigger than Big Mac. Drama drama drama!
 
2 part eg crossover episode sunset takes in homeless Dazzlings and open their eyes to what real friendship is. When she takes them to Equestria to show Twilight, the lack of evil in their hearts turns them from sirens… Into PONIES!!!  
Adagio screams in rage  
Aria screams in fear  
Sonata screams in joy
 
Light hearted zombie episode and Rarity will be the one of last ones and save the day… Wait What?!?
 
Twilight is s desencdant of Starswirl!!!!
 
Rainbow takes Lightning in after she is completely fired for a misunderstanding when she actually tries to help somepony
 
Caramel, Noteworthy, Written Script, Neon Lights, Fedric horseshoe pin, dr whooves, Thunderlane, Flash sentry, CMC’s counterparts Rumble, and Button, and featherweight all need better status! MORE BOY TIME!
 
Lyra and Bon Bon need their OWN episode
 
More applejack episodes… And actually make them good!
 
Cheese sandwich returns! And for God’s sake have him meet Discord!
 
Mane6 team up with background6!
 
Rainbow…Soarin…crappy date…happy end! NOW!  
Or at least have some guy we actually LIKE develop a crush on Applejack (caramel?)
 
More idw eeferences
 
And finally…Drum roll…
 
Twilight gets to be a villain!! Sombra’s magic=  
Shadow Twilight! Go save us Starligh- …
 
 
We’re DOOMED…
 
Unless Sunset of course…
 
So what do you think?

And to cement the BG as Los Pegasus, you can see a ponified Sphinx head, so that + the pyramid is the Luxor hotel:

@Masem  
By the gods, YES.

I just realized what AJ’s outfit could imply, if you remember this other teaser image:  

 
NASCAR NASCAR NASCAR

@DragonMorpheus  
It’s absolutely meant to be Los Pegasus, there’s no other explanation for the roller coaster and the giant pyramid.

I’m kinda curious about the background. Las Pegasus, perhaps?

So Applejack appears to be covered in what looks like motor oil, wearing a cap with Big Mac’s cutie mark with inverted colors. This could be leading to something interesting.

Why does Rarity’s face here look so familiar?
