S04E22 — Wedding Balls

Will expects two friends to arrive in New York to plan a wedding, but when the bride-to-be falls ill, he asks a willing Grace to work with the clueless groom to work out the details â€" but she gets a little too involved in the dreamy details and fancies herself a bride instead. Meanwhile, Will and Karen get chummy over a steamy potboiler book that they're both reading which leaves a jealous Jack fuming as the odd man out in the book-of-the-month club.
