Story[]
Dr. Hoffman and Kasal call Derek to the office to discuss his recent operation on Linda Reid. They inform him of a mysterious disease known as GUILT that has claimed several lives in recent history, and show that Linda was tested by an external organization and confirmed to be a GUILT victim. Derek's Healing Touch ability and his recent successful operation has earned the attention of Caduceus International which seeks to recruit him.
Derek is a little reluctant to join Caduceus as he prefers the close doctor-patient relationships at a small-scale hospital. To better illustrate the threat of GUILT, Greg lets Derek read a cryptic letter that the hospital received shortly before Linda's admission. The timing of these letters and GUILT outbreaks have led the WHO to believe that GUILT is a man-made disease and cannot turn a blind eye to the acts. Derek is shaken by the news and Hoffman urges him to carefully consider his decision.
