Oh, what a fascinating scenario--not just two people whose families bring a host of assumptions and prejudices about the background of the other, but two families that have very specific reasons for wariness about crossing the magic/muggle divide, as well as personal experience of the animosity between their worlds. A great story to tell about these two characters. The moment of tension between Dudley and Millicent--the threat of fist and wand--showed how their backgrounds continue to influence their relationship, affection and good intention aside.
