You ask Autumn Gold what kind of "together" she means.

Autumn Gold: "To be honest, when you're this close to somepony, it's hard to put a label on it."

Lucky Smith: "Are you asking if we're best butt buddies? Because that's a secret!"

Leaf Chaser: "Is it a secret? 'Cause the other day, I was flying over the orchard, and I'm pretty sure I saw you two—"

Lucky Smith: "It's a secret‼"

The family bursts into laughter. Autumn Gold rolls her eyes, smiling amusedly, and begins to stack some of the empty plates and trays in the middle of the table.
