"Y-y-yeah!? A-and you don't like that, right!? N-nicknames chosen by other people without our input are bad! We should call Emmie by her name! A-a-at least until she can decide things by herself..." Even Chako knew this was a terrible comeback... But she just had to say something!
... And had to keep playing with Emmie, so she started moving her tails around near Emmie's cheek, letting her pick a tail if she wanted to... And bracing herself for the possibility of having a tail filled with drool.
"W-wait, hold on, what!? An airship from beyond this world!? Y-you mean an Alien airship!? You're not saying it's from Earth, right!? Like, some other world beyond Arcia!?" Chako didn't even know this world's name yet, but still, not even from a different continent than Arcia, but straight up an alien airship!? She did not expect that!
The next part was also amazing, but in a much lovelier way, "So you could talk before you were born Emmie? Did you talk from within your egg? That's so amazing! You're such an amazing girl! I can't wait to hear you talk!" Chako tilted her head a bit, "Though I wonder what made you stop talking... Was getting out of the egg tough? Did it mess up with your vocal cords? Well... If you need healing, you know you can count on me! I'm good at healing magic, Emmie!" Though Emmie really felt like a normal baby, so... "Or was it your mind that regressed? That would be a shame... But you can always learn how to talk again! I trust you! You're an amazing girl, after all!"
