Resolution: the clan gathered for lunar new year, and it turns out one of the cousins actually went to the same college as the groom and knows him slightly. He also fits into his father's evening wear, can get time off work (family business, run by his dad and uncle since our parents retired) for a long weekend and thinks it would be a "hoot and a half" to show up as Sprout 1's guest. They are both tickled -- especially since he also plays Sport. I got him a miles ticket (which neither of them asked for -- he was going to pay), he'll stay with her, and I think they will have a very good time. Thanks for all the great input. And since he is her cousin, they can both use the party to meet others!
