You called?
 

@OptimusPrimevil  
I dunno, for some reason I’m now thinking that Sardonyx would work best for Rarijack.
 
At the very least, you have to admit Rarity would make a pretty good Pearl.

@Scrounge  
all we need now is someone to use both of them in a sexual manner (as in “we felt USED!!!”)and they have a massive rage fit to complete the comparison.

@OptimusPrimevil  
I take back what I said. While they’re not always literally a single being, they are seen together pretty much always now. Garnet is probably the best answer and I apologize for contradicting you.

@OptimusPrimevil  
Not sure what to say. Um, good luck?

@Scrounge  
speaking of garnet, can’t find a good pic of lyra being patient. bonbon has at least two pics being furious and this is their ‘conversation’

@OptimusPrimevil  
And the only reason I’m not agreeing with you on Garnet is that they probably aren’t going to stay like this for more than eight hours, ten tops. ;)

@Scrounge  
rainbow quartz is only valid if one of them is trying to make a male love interest jealous.
 
dammit pearl!

@OptimusPrimevil  
Amethyst and Pearl have shown some signs of giving a shit, even if they do drive each other crazy…
 
But mostly, I said that because I thought the options were either Opal or Sugilite at that point, and a destructive Lyrabon rampage seems unlikely to me. (And because one of them actually has turned into a giant woman… Well, giant mare)
 
But I’m changing my answer now that I know about Sardonyx. This would totally be Sardonyx.
 
Or Rainbow Quartz, I forgot about Rainbow Quartz too.

@Scrounge  
but opal is a fusion of somewhat barely tolerating each other co-workers.

@OptimusPrimevil  
Or at least Opal. (The gem fusion, not the cat.)

@lasty
 

No, you’re Garnet: made of lesbians

Nope, yer a CatDog

@Background Pony #E5CF  
she’s garnet now

Doesn’t really fit, considering how much Bon-Bon and Lyra like each other.

Really? Me, too!  

 
You rang?
