Langston Miller as he appears in Trauma Center: Second Opinion.

Langston Miller is the British director of Caduceus Europe. He keeps sinners in his lab to research how the body captivates the GUILT and tells Derek that he used technology linked with Triti to easily remove cancerous tissue. He supported Derek in the operation of Triti. They used high vibrations to kill cancer, but the cells of the technology didn't know between the cancer cells and the healthy ones, so the technology made the strain Triti. He also used Z cells from GUILT to help people, but it ended up being GUILT cells.
