Dr. Mark Kaylis was a physician at the CTU medical clinic during Day 4.

Day 4 Edit

Dr. Kaylis was the physician for Maya Driscoll, the daughter of CTU Director Erin Driscoll, when she was admitted to the clinic. Due to a mixup with her file, he administered Haldol, to which she was allergic. With help from a nurse and some other medical staff, he revived the young girl. Dr. Kaylis was replaced by Dr. Sanford afterward.
