That would be Durge. I think the main reason we never saw more of him was cause Kenobi killed him and there was never any build up to his arrival or any kind of mention of him after. Just some guy who could have been a general or some mercenary. Also a primary antagonist who just doesn’t talk or have any personality but being big strong guy definitely doesn’t add well to the tv formula.
Odds are if a church was involved, one or both are gaslighted into believing they are meant to be married that other person for better or worse, and regressive enough subculture/community that finds divorce abhorrent for any reason (other than the man could have a younger bride)
