And thus we have an example of some of the Biblical Tenants against "coveting your neighbor's wife", though commonly, it was through the means of a bondservant by which a person was sold into slavery/bondage due to an inability to pay a debt/sin (anderarum—assuming I spelled that correctly).
I never really got the whole "possession" thing. Resentment over someone picking a pretty jerk ass, maybe, but thinking that one is owed sex like this—eww! I guess as a guy I don't see the appeal of sex taken by force. Revenge being an exception, but the whole power over the weak thing—bleh. Never saw the appeal. I guess it takes a certain kind of crazy? Shrug.
Well, presuming that was foreshadowing for the invasion excuse—I imagine we'll see him save the wife and there be some plot reason involved to demonstrate that he's not sociopathic and villainous, unlike the opposition nobles.
