Chara then adds her magic to the performance, a trio of fireballs appearing to orbit her on her command. The mare plays with fire in front of your eyes, quite expertly so. For a few seconds you even forget the sexy component of the dance as you marvel at the mare juggling the flames on her hooves or making the balls roll along a wave of her arms and back. But you're reminded of it quickly enough, as the mare then bounces the fireballs off her butt, all while theatrically presenting the audience a faux-outraged pout.
Chara finishes her performances after few more spins, earning her the ecstatic applause of your group and of many other patrons and passers-by who caught a glimpse of the fiery mare.

"I think we're on the same page you and me, aesthetically speaking." Chara comments as she sits near you again, her seat now creaking much louder under a rump that can no longer help but to rub against yours. "Oh, I think I will enjoy this trip with you, Hearty. At this rate, the show I might give at Sky Diamond might end up being the biggest one in the history of ponykind."
"Sounds like I should book my seat already." You smile back, tastefully crossing your legs to hide your enthusiasm. "Because this is exactly the kind of project I had in mind when I learn my spells."

You share a couple more drinks and toast to the success of your musical collaboration. As night gradually falls outside, you move on to other topics.
"Say, I've meant to ask." You turn to your whiskered partner. "Would you like me to use my magic on you, Hilda? And to make you bigger?"
"On me?" The rodent cocks an eyebrow. "Would that even work? Well, in all cases, no thank you. I wouldn't nearly be half as efficient in my trade if I were bigger, and let's not even talk about how my buttocks clapping with every step like the ones of the fire wench would be the end of my flawless stealthiness." But then Hilda seems to give it more thought, and soon doesn't sound so opposed to the idea. "Unless… Maybe if you could make me, like, WAY bigger. See, it would be another story if I could be the large one among ponies for once and replace the sleuthing with some smashing! I bet you would all finally show the due respect to my form. And don't worry, I would carry you just like you carried me. If our roles were reversed, I would not forget your diligence, and abide the rules of bigness oblige."
The truth is that you can't know whether trying to grow Hilda will work without trying. Ratchel told you at the time that 'there is a lot of pony in Hilda', which made you consider that it would be possible at all. Anyway, your magic just wouldn't work and you wouldn't spend any mana if you tried and that your magic ended up having no effect.

>What do?
>Attempt to grow Hilda?
>Anything else you want to tell your friends?
>Turn in for the night? In the comfort of the embrace of Brass Compass?
