Sydney’s twin brother. He was once a “Special Expediter” at The Centre and was responsible, in part, for processing the children for The Centre’s Pretender project: PRODIGY. He was the one who signed-off on the paperwork that transferred Jarod to the custody of The Centre, but it was Mr. Fenigor who actually had Jarod abducted.

When Jacob attempted complain about his duties and to leave The Centre, he was threatened by Mr. Raines… and a few days later severely injured in an automobile accident (on August 2, 1967) that left him comatose. Sydney had been keeping Jacob at the Mount Pleasant Home and was seeing to his on-going treatment, but had to move Jacob to another location when Mr. Raines found out that Jacob was still alive and sent Miss Parker to the Mount Pleasant Home with Sweepers to kill him.

In December of 1996, Jarod experimented with the Halstrom Technique: a therapy meant to revive coma patients. The therapy worked on Jacob for a short period of time, and during his lucid moments, Jacob told Sydney about the mysterious “SL-27”, and absolved Sydney of the guilt he felt over the accident that had left Jacob in his 30+ year coma. (Sydney had been driving the car in which Jacob was injured.) Before losing consciousness again, Jacob scribbled a note to Sydney: “Not Your Fault”.

In January of 1998, Jacob was again revived briefly by a viral brain infection that re-awakened the damaged part of his brain and allowed him the opportunity to again speak with Sydney. Unfortunately, the virus that re-awakened him also killed him in less than a day, so Sydney was unable to get much information out of him except a cryptic hand-written note that read: “GENE”.
