Despite what your mother told you about not following strange colts you've never met into alleyways in towns you've just arrived in, you can't really help yourself. This guy is just so handsome and mysterious. And mysteriously handsome. And handsomely mysterious. Oh you get the idea. The point that, despite your extra-pudge you've got around your midsection, this fellow is very interested in you.
"Hello, miss." He says, "I couldn't help but notices that you're not like the other ponies in this town. And neither am I."
This guy sure is confusing, "Are you coming on to me?"

You're taken back, "How did you know who I am?"
"Well, that's the deal. I saw what you did, that belch. As a man of science I could not sit idly by while a pony capable of creating seismic disturbances with her gas just walked around my hometown.

He leads you all the way to the back of this surprisingly long alley, right to a small area surrounded on all sides by a chain-link fence. They must be doing some construction around here.
"It's right over here, with this machine we'll be able to take care of your little problem." He motions to a device covered with a tarp.
"Listen," You say, "I don't think I could even do that burping thing again. This all seems extreme, and I'm not really comfortable getting on any machine that a doctor in a back alley built."
"Alamode, please," Doctor Whooves says, "I just need you to trust me. This machine is completely harmless. All it's going to do is take care of any future outbursts by..."
