Reintegration is an experimental process by which an individual implanted with a Severance chip is no longer under its control. The actual process is vague; it does not involve removing the implant. If performed successfully, the result is “full synaptic recoupling.”
Reintegration is performed secretly by Dr. Reghabi, a former Lumon Industries employee. She is a surgeon who performed Severanceimplantations for the company.
The first person to undergo Reintegration is Peter Kilmer. He later died, possibly from Reintegration Sickness. Per Reghabi, “…[i]f he had followed my post-op instructions and not simply run away at the first sign of sickness…” [1] implying that Reintegration sickness is not a foregone conclusion of reintegrating.
The Board does not acknowledge the existence of reintegration.
When Harmony Cobel retrieves Petey’s Chip, people in R&D found evidence that he underwent reintegration. The Board agrees to meet with Cobel and hear out what was discovered. However, that meeting never took place thanks to the unfortunate events of the Eagan Family Gala.
