Alan Crenshaw

Alan Crenshaw (age: 40s) is a CIA lab technician who worked on the Leafman Project and the Ambrosia Project. Over the course of the series, he develops an unhealthy infatuation with Doctor Nikita Sonin and becomes obsessed with her performing surgery on him.

Lab Injury
When CIA Agent Claire Maddison misremembers part of an Omphalos vision because she is distracted by an argument she had with CIA Agent Jack Turner the previous night, the incorrect formula that she gives to the lab techs results in an explosion. A piece of shrapnel becomes lodged in Alan's ribcage and he is rushed to Mercy Hospital where Doctor Nikita Sonin operates on him and saves his life. After this, she checks up on him periodically throughout his recovery and he becomes fascinated with her emotionally distant personality.

Implant Removal
Later, Alan comes to the emergency room with an infected wound on his arm and refuses to talk to anyone other than Nikita. Nikita examines the wound and determines that a foreign object has been inexpertly implanted in his arm. Alan says that it must be a top secret CIA mind-control implant and that he only trusts her to perform the surgery to remove it. Nikita initially refuses because the procedure will be very basic and a waste of her talents, but reluctantly agrees to do it after Alan says that the implant includes delicate monofilament wires that connect to his nerves. When Nikita performs the surgery, instead of a sophisticated piece of biotechnology she discovers a broken piece of a circuit board. When she confronts Alan with this, he breaks down and confesses that he implanted the piece of circuit board in his arm as an excuse to get her to perform surgery on him again. He explains that he is wracked with guilt from the deaths caused and lives ruined by the Leafman and Ambrosia projects and that being saved from death and cared for by someone so devoid of sentimentality felt like objective proof that his life was worth saving after all. Nikita explains that since his problems are clearly psychological rather than physical, there is nothing about him that interests her and threatens him with a restraining order.

Death
When the CIA learns that Nikita has figured out how to reverse Maudling mutations through surgery, Alan decides to defect to the Maudlings in the hope that he will be mutated, giving Nikita a reason to operate on him again. When Alan arrives at the Maudling compound and asks to join, the Maudlings are suspicious (likely due to Deemlind's recent death) and shoot a beam of light through his chest, killing him.
