We all have it

"Arian Adravendi, I'm sorry for intruding. My mother is Epiphron and she told me I didn't need permission to enter Fiori so I thought I would look for my family here. I did find what I was looking for though." she grinned at Vitus looking at the owl as well. "I'm one of your aunt's I just wanted to say hi and pass by since we've never really had a chance to talk or meet." if he was a mute she was no stranger to that. Spending time around Sarka(which Vitus had met before, though Arian didn't know that) one of Azalea's children she had learned to communicate through those signs of body. So she and Vitus could have an entire conversation without speech if he so wished it.
