Mr. Raines is a shadowy, high-level operative within the Centre. A former psychiatrist at the Centre (he was referred to as "Dr. Billy" by young Centre residents), Dr. William Raines worked with Sydney on the Pretender project until his license was revoked. Mr. Raines conducted his own Pretender experiments within SL-27. His pet project was turning Jarod's brother Kyle into a sociopath. Another of his projects was the savant Angelo, whom he offered as assistance in the hunt for Jarod.
