It was like that!” she then points at Will (Eric Cormack) and Grace (Debra Messing) who are staring blankly into the distance. “Your paw’s inside your maw!” Karen later squeals, as Will takes a sip from a glass of whiskey. “And nine months later, a dust baby!” Jack responds, bursting into laughter and slapping the table. Will and Grace then respond angrily in unison, “COME OFF!” Karen and Jack try not to laugh before Grace cries, “Why did your mother throw her garter? And why am I still holding it?” The first episode of the show reboot’s second season (the show’s 10th total) will also see Grace accidentally running into Noah, a potential love interest, played by guest star David Schwimmer. Will & Grace is set to premiere on Oct. 4 at 9 p.m. on NBC. The Will & Grace reboot is nominated for five Emmy Awards.
