Agnes’ surprise

Anges gazed at the Dragonborns with a stupefied look on her face. She had never seen such striking scales from a demi-human before. 

Not only that, but their frills made them look very similar to the draconian race that dominated the world a couple of times throughout history.

As she watched the young red-scaled Dragonborn 'play' with the drunken dogfolk, she saw the overflowing natural strength and talent he had in the Physical Arts. The Dragonborn was clearly a novice, with his moves lacking efficiency and control, but his strength and power were clearly on par with veterans.

She knew talent when she saw one.

Agnes wouldn't admit to this, but she was considered to be one of the best Physical fighters in the entire continent. She was the reason why Yuna's parents allowed her to travel so far from their home.

So, when she admitted that someone was more talented than she was, it was the truth.
