Getting an artificial master level mage as our ally is a great addition. Though our expert level mages are stronger than the cult's artificial master level mage, it's still a great help for Iris to join us.
After getting her join us, Albert asked her some more questions. And then we let the Professor to talk with Iris, but it seems like it wasn't necessary. She hated him for experimenting on their son even if that's the only way for the boy to recover.
If only the medical knowledge of this world has advanced just ten years into the future, she could just ask any reputable surgeon to operate on her son. And she doesn't need to go to the cult to ask for help.
After hearing Iris' report on her son's condition, I can tell what his illness was, and I could heal him by performing surgery. Though it happened a few years ago, even before I returned back in time.
