Dr. Avery is a children therapist. Had the little Emma Person under his treatment. He told her mother that she suffers from Corona Syndrome and handed her over to Doctor Frey.
A week later her mother brought her to Dr. Avery and Dr. Frey to take her to the clinic. Instead of Dr. Frey Avery saw two men, Mr. Finn and Mr. Jones enter his office who took her to the clinic.
