We have lost containment.

@absolfusion  
Which was why I avoided that one.

@Trilby Pony  
what about Rosy Quartz? That would even be named after her… wait.

I love that the Clone That Got Away tumblr sudden became canon. “Diane” even escaped to Manehattan in the story.

@Scrounge  
That’s much better than Rosey Rock. I vote Marble Cake for the Pinkie Clone.

@headlessrainbow  
Doomie wasn’t this good at being Pinkie though..
 
 
@headlessrainbow  
@Trilby Pony  
Or she takes the first name from her twin sister, and the last name of the family she lived with in Ponyville, and calls herself Marble Cake.

@headlessrainbow  
You mean Envy the Changeling?

@Vinylshadow  
If it is, it better be Doomie

I think that clone has avoided being murdered by Twilight long enough to deserve her own name.

Probably a Changeling

I want to name her.
 
I will call her “Rosey Rock.”
 
If the Peter Parker clone could get away with using Uncle Ben’s first name and Aunt May’s maiden name, I think a Pinkie Pie clone using a synonym and part of her father’s name.

This is the moment when I lost it. I mean for real, just fell over laughing like I haven’t in a long time, could not keep watching the show I was laughing so hard.

@karstvgl  
Ooh~  
Freaky thought!

>Season 6 finale villain

Changeling - Eyes not green, possible but implausible  
EG Pinkie Pie - Possible but so far the franchises have not been connected (or else we’d have seen Sunset)  
Time Traveling Pinkie - I mean, this is Pinkie Pie so… maybe  
Mirror Clone - Directly implied by the script having another Pinkie appear when Pinkie was talking about clones

@Inkan1969  
Given what happened near the end of the opener, I really wouldn’t be surprised in the least if this was another hint at something and it is a Changeling.

@Background Pony Number 17  
So far:  

@Inkan1969  
A proper scientist explores all hypotheses.

@thewerehog  
It’s interesting how Pinkie is talking about the clones specifically, but people have noted several other plausible explanations for this double.

@Dirty Bit  
nope, this is our pinkie.  
one was just lost in teh crowd and was afraid she would get poofed…….
 
think she might have been the very first one.

@thewerehog  
I don’t know which one I would like it to be more, Equestria Girls Pinkie, or a Clone. Both would be amazing.

could be eg pinkie in the pony world

One escape

and more than a couple of fanfics were validated
