(I'm going to do a little modding of Azure here, though i can always have what is said here just be really bad rumors or i can go back and change it as you see fit.)
Instead of striking at the....undead?....Zetrin just keeps his hammer pointed at the creature. He then looks over at the woman and smiles a little at his luck or miss fortune. He quickly looks over the woman studying her current form, though he doubted that he could deduce anything real about her if the rumors were true. "Aaahhh, The Azure Witch I presume? We finally meet, though I'm not sure if this is a good or bad thing yet." He thinks back to the rumors again and remembers a clear detail he had heard multiple times. "Hhhmmmmm, odd, she doesn't look like a hag." He whispers to himself.
He then returns to the question at hand. "Yea, I can let him go if you can answer a few questions for me." He had a feeling what she meant given her current form, but he was still in business mode.
