Dr. Ranui hums at this news about Ms. Gunzenhauser, looking thoughtful. "I trust you kids to know if something's amiss. Thank you for coming to me. It's probably just that she's been under a lot of personal stress, but we do take this seriously. I promise I'll speak with her."

As for Ms. Treetops, he seems a great deal more light. "Oh, missing!" He laughs. "No, no, she had a family emergency. We were quite worried, as well, after a student reported that she was gone, but she got in touch with us a few hours later. She should be back this week."
