Vinny was originally unsure just how far his friend Ansom should trust Jillian. While Vinny had some doubts about Jillian's loyalty, they seem to have respected each other professionally, and fought well in combat together. Their mutual grief over the reported croaking of Ansom brought them together at a deeper emotional level, and Vinny worked hard to make sure that Jillian and Don King had favorable first impressions of one another. When Faq was rebuilt, Vinny was assigned as a diplomatic liaison.
At some unknown point the two became lovers. Vinny tried to persuade Don King not to demand that Jillian pop a heir, in part because he feared it would ruin their relationship. While their relationship has become increasingly strained due to Don King's demands and Jillian's secrets regarding her alliance with Charlie, it is so far intact.
