Fluttershy went through the Crystal Mirror to get Angel since he went through the mirror. However when she went through...she noticed something. She lost her wings and hooves. She was a human. She walked the city after getting Angel and placing him in her bag. She noticed you.

Fluttershy: "E-Excuse me. I'm a little lost. Can you please tell me where I am? I hope I'm not asking for a lot but I'm new here."
