As the fourth season of NBC's award-winning comedy begins, Will (Eric McCormack) has just returned from France--alone--while Grace (Debra Messing) is still seeing Nathan (Woody Harrelson). Meanwhile, Jack (Sean Hayes) is adjusting to fatherhood of newfound preteen son Elliot (Sky High's Michael Angarano), while Karen (Megan Mullally) remains, well, Karen. Alas, in "Crouching Father, Hidden Husband," the authorities finally catch up with her (never seen) tax-evading hubbie Stan and toss him in the clink. Grace's relationship with Nathan, on the other hand, continues to blossom until talk turns to marriage in "The Rules of Engagement."
