...or why they would be... could be...should be.
*******MAY CONTAIN SPOILERS!!*******
Henry is a somewhat womanizer when it comes to food, but I think that it would subside if he were to date Vicki. The two are polar opposites and that's why they attract. Henry has had 550 odd years to find someone, and chose Vicki, who was different, out there.
She wasn't afraid in combat and spoke her mind clearly. She is bull-headed and stubborn, but went with her gut instincts. Henry and Vicki made the perfect team.
