You explain you're not there to hurt the pony. She let out a little squeak. "Are you sure?"

You hold up your hands and take a step back.

The gesture seems to sit well with her and she lets out a thunderous sigh. "Why did you chase me like that!"

You explain that ponies are not a common sight, and you wanted to meet her.

Her cheeks warm a little. "Me? Well... hi!" She waves a hoof at you. "Nice to meet you..." You give your name. "I'm Starfire, and now that we've swapped introductions, you can stop chasing me around town?"

You assure her that talking to her is better than chasing her around. You ask her what she's doing.

"Being lost, and chased..." She scuffs a hoof on the ground, kicking a rock into the little stream. "Look, you seem... nice. Maybe you could help? I need to get home, or at least a safe place. Can you help me?" She gives a smile as big as a pony could give, which is pretty big. "I'd be ever so grateful."

You want to help her, of course. It sounds like others have noticed her, with the distant noises of sirens and other activity. She couldn't just stay there, and wandering around sure seemed like a bad idea.

Perhaps you could take her home and proceed to Chapter 1B1
Or you could take out your phone/laptop and show the wonders of MLP to hopefully explain where she's may have come from,
head to chapter 1B2
