You tell Leaf Chaser that you were just about the ask her the same thing, and suggest catching up over a quick meal.

Leaf Chaser: "Yeah, let's do that!"

Autumn Skies: "Actually, I'm afraid we have to be home for supper. It's Chaser's turn to cook tonight, and she's not getting away from it this easily."

Leaf Chaser: "Aw, butt muffins..."

Autumn Skies: "To answer your question, we flew up here for today's flight practice, and decided to have a look around. What brings you two to Canterlot?"

Moonflower: "We're here to take the train to another city so we can go to a mysterious island with a big tree in the middle of the ocean!"

Leaf Chaser: "Wow, that's so cool! Can I come?"

Autumn Skies: "You know the answer to that, filly."

Leaf Chaser: "Bummer. Well, don't forget to bring drawing supplies! You can't just go exploring and not draw maps."
