In 2492, a series of incidents occurred at Luna OCS Academy on Luna. They involved the overnight disappearances of his daughter Inna Volkov from family officers' quarters on base, sightings of her in the company of a young man, and a child produced by those liaisons. On June 7, 2492 six cadets were brought before a Board of Inquiry to testify. One of these was a young Preston Cole. Though Cole was not found guilty of any wrongdoing, he married Inna two months later, with the admiral acting as a witness. The child, who was not Cole's biologically, was born December 12.
In his report on Cole's life, Codename: SURGEON suggests two reasons why this marriage took place. The first was the Admiral knew which cadet was the true father and didn't like what he saw, thus finding a suitable replacement for his daughter: Cole. A second was that the child was not the offspring of any of the cadets and thus the Admiral's grandchild would have been fatherless. The third was that Cole had the liaison with Inna, though was not the father of the child. Either way, Admiral Volkov either made Cole marry his daughter, or Cole married her because of a sense of chivalry. The admiral certainly seemed to have liked Cole. When Inna filed for divorce in 2500, Cole wrote back stating that it must have been how she truly felt, as her father would never have pressured her into leaving him.
