Nigel Weir was the warden of Persephone. He was originally a fairly brutal, cold-hearted warden, but when Sofia Lamb fully took over the prison she convinced him to have a change of heart. His Audio Diaries suggest that he was complacent with his role in Doctor Lamb's work at the prison. As long as it helped him to keep his position of warden, he didn't really mind lending prisoners to her for her "therapy sessions." He seemed unaware of the fact that some prisoners had secured parts of the access code to his tower and were close to storming it.
