Awwwww sad unicorn face! Jenny's heart is melting. "We don't know why we're here either?" she offers. "It's just a friendly magic bar with tasty drinks, I think!"
"But I didn't see it!" says the unicorn. She peers around anxiously, then her horn glows gold and she shuts her eyes.
Er. Is she blind? Is there a polite way to ask? What's polite for a unicorn? (unicorn unicorn unicorn!) "But... don't you see it now...?"
The unicorn opens her eyes again; her horn dims. "I mean I didn't see it in advance with my spell. And it doesn't work here at all!"
There is a star on her butt.
"Is that why you have the star? That's adorable!" Jenny says enthusiastically. (Unicorn!) "Also. Hi! I'm Jenny! I'm sorry about your future...seeing...thing?"
"The star isn't because of my name, it's because of my talent," says Guiding Star. "Uh, it's nice to meet you."
"I'm Lexi," Lexi puts in. "I have never met a unicorn before!"
"It's very exciting! You are many wonderful bedtime stories come to life! Seeeeee?" Jenny nods at Mr. Fancy next to her.
"It wasn't on purpose! I was returning it to my little sister and then the door wasn't the door it should have been and now I'm here. Me and Mr. Fancy both."
"Are you from Earth too?" Is there an Earth with unicorns, Jenny might have to move.
"Must be a different sun. That or we had different lessons about the solar system growing up."
"Probably both," she says cheerfully. "What else is different? Are there more unicorns where you're from?" (!!!!!!)
"Yeah, plenty. About a third of the ponies in Ponyville where I live are unicorns."
"Ponyville, awwwwww, that is completely adorable. It sounds so nice! Can the pegasi fly?"
"Well, in our world, the larger something is, the harder it is to fly! So I wasn't sure." She reconsiders Guiding Star's size. "Maybe it's not as much a problem for you...?"
