Killué was flying.
They weren't sure where, or why. They were just exploring, really, trying to find people to help. They enjoyed helping, though a lot of people seemed to be afraid of them. That confused them and made them sad.
But as they're flying, they see a strange sight: a group of people, standing around, talking.
They smile and swoop down, landing in a tree, not noticing the other person that was in it.
The othe rperson would probably notice them, though, considering Killué's bright colors.
They listen closely, tilting their head like a confused puppy.
