Expect a lot of character development. Since they come from different backgrounds, their marriage would be a journey of getting to know each other better. There could be scenes where they teach each other things. For example, Barriss could teach Cody about the Force in a more personal way, and Cody could show Barriss the camaraderie and loyalty among the clone troopers. It could also be a love story that unfolds in the midst of the complex and often dangerous Star Wars universe.
