Stephen Clarks is a character who appears in Under the Knife, Second Opinion and Under the Knife 2. He is kind and caring, which comforts many sick patients. Apparently, he didn't do a very good job against Deftera, being only able to thin out some of their tumors. It was originally intended for him to operate on Linda Reid when she had Post-Kyriaki, but seeing who she was made him let Derek do it instead. He is head surgeon at Caduceus USA in Under the Knife, Under the Knife 2, and Second Opinion.
