Not Pinkie Pie

Crystal, you seemed surprised once you heard that the princesses were coming.

Cotton Candy, what's your plan for when the princesses show up?

If all your magic was drained, would you revert back into butterflies?

Can't you just dye yourself not pink?

Your home looks amazing, Holly. You must've had some help cleaning and repairing the place to be liveable for you?

In order to not sound crazy, just give her a random sounding excuse. Just don't mention Twilight and her friends.

*Holly, seeing a sad Crystal, flutters over and hugs her*

There are other universes where there's some Pinkie Pie clones that escaped from Ponyville and are currently living new lives under new identities without Twilight and her friends knowing about them.

You can't yell at them to be friends. Go and see what's the problem is, Cotton Candy first. We'll all be here to give you help.

Can you give everyone a tour of your home, Holly?

Friendship problem at 12 o'clock, meaning ahead of you. It looks like it's a big enough of a friendship problem that the map is picking up on it. You need to hurry before those mares find their Cutie Marks glowing and go check the map. Find out what's going on, give some advice, like if it's caused because one pony is not honest to another or whatever, and solve it before it's too late.

I have to say that Queen Chrysalis is my #2 favorite Equestrian villain. She may be evil, and used to have a kingdom and loyal subjects/army, but she's still pretty dangerous and deceptive in her own way. Sounds like one tough mare, Crystal. If you were to encounter her, what would you do?

I guess you being created thanks to my chaos magic must've given you a special magical power, Holly Blue. Make sure you use the power for good, okay?
