He's twenty-seven. Someone his own age is young and unless she's a bona fide troll would be considered a trophy wife by many.
Being 27, and single with no prospective wife in line, I would think it is safe to assume that several years at a minimum will pass before he gets married. So, best case scenario we are looking at early 30's, but more likely mid to later 30's as the date of his marriage.
Unless he gets a foreign import from a catalog.
