She revealed that Null was now in the business of producing mutants, and that she needed Lindsey's help in creating the ultimate mutant, having failed repeatedly to produce viable results.
After Old Hob destroyed her lab, Jillian brought Lindsey to meet Null, attempting to convince her ex-girlfriend to take the job with the corporation. However, after Null made it clear she had no choice in the matter, it became evident to Lindsey that Jillian was also trapped, and had had her kidnapped because she was hoping that Lindsey would help her escape her current predicament.
She was initially pleased when Seymour Gutz returned to the lab, claiming that his suit had been damaged and was killing him. But before she could examine him, Seymour revealed that he had set himself up to explode, in hopes of taking the cruel scientists with him.
After the explosion was averted, Jillian was ordered to wipe the research and information on mutants, and then gave Lindsey all the information on their animal testing. In response, Lindsey then punched Jillian and tied her with a cord, leaving her to face the consequences when the Null guards arrived.
