Will & Grace

NBC | 9:00 pm

Another actor from the original series returns, as Harry Connick Jr. reprises the role of Grace’s (Debra Messing) ex-husband Leo in the new episode "Emergency Contact." The title describes just what Leo is when he’s summoned by Grace’s doctor instead of Will (Eric McCormack). Jack (Sean Hayes) adapts well to his new job. Karen (Megan Mullally) makes a new, and young, friend.
