Perhaps, saying the name out loud, Quinn was expecting somewhat of a reaction from Hannah, but there was nothing. If Tinker didn't know what the leaders' names were, it was unlikely that Hannah would know either.
For a split second, Hannah saw a change in Quinn's expression. She knew he was expecting something. Seeing this made her recall the time when she first saw him. When the two first met, she wasn't afraid of him even after knowing his great strength. She just knew that she needed to be cautious and not get on his wrong side.
Honestly, even after seeing what this vampire could do, her opinion didn't really change. In Derik's incident…she had figured out what most likely happened after she had time to think about it. During the fight in the room, her reactions were irrational after seeing the Dhampir.
