- History and Experiences Which have Affected Character Greatly: Clarke is a result of the two years Jerry LaSaille spent at Starfleet command between ships. Eshi took him on a whirlwind ride. Bore his child and turned clingy. He wouldn't quit Starfleet for her.
While the marriage didn't end, it took on a distant quality. Jerry spent time with the boy when he could, but tried to keep a healthy distance from Mother.
During his years as the Commandant of El Nanth star base 2278 to 2283 Jerry spent a good deal of time with Clarke. These years are the true basis of their relationship. Even later in Starfleet Headquarters Jerry would use the Express to get a quick weekend back home.
Time with Dad was a treat. His Mother on the other had made every effort to bind her son to her, and for the most part it has worked. Jerry was simply not around enough to counter the influence.
Clarke when first seen is currently drifting. He isn't really seeing anyone, or planing his future beyond teaching research. He has considered moving to Crystal City to get away from his Mother, but for some reason it never happens. Time with Dad is golden, but far too rare.
Clarke is later seen as the farm manager at Bellacolone several decades later. He stayed on Earth and found a wife, had kids.
