Zale and Liz observed Han diagnosing Serf. They observed the process such as when the physician put an instrument on the prince's chest. Checked the eyes while flashing light into it. But what shocked them was that the physician made the prince take off his shirt during the process. Liz wanted to run to the physician and stop this abomination, but she couldn't. On the other hand, Zale was in awe of the young physician's skills.
As Han finished diagnosing Serf, he gestured to Zale and Liz that they could come here now. Seeing the gesture Liz hurriedly went towards them while Zale followed. "Did you find out what's happening? How bad is it? Can he be cured?", before Han could say anything the mother bombarded him with questions. Seeing how the concubine was acting Zale sighed.
