While Jack fills in for Karen at the office, Grace finds out about an old fling of Will's she does not know of. This worries Grace so much that she and Jack rummage through Will's things to find clues of what else he may be hiding. On his planner, they find out that he is having dinner at the Astor Cafe with "K".
Grace, completely obsessed at this point, goes to the restaurant to confront Will and becomes speechless learning that he is meeting Karen as a client. Back home, she apologizes to Will admitting that she acted uncontrollably paranoid because the last secret he kept from her was that he is gay and it changed her life completely.

- The episode was the first time the story line was divided between Grace and Jack, and Karen and Will.

You know I thought I knew everything about you. But you’re a mystery. Wrapped in a riddle. Surrounded by an enigma. Growing boobies. — Grace
Karen files her nails and thumbs through catalogs all day. What's she going to do on a vacation? I guess office work. — Will
|Secretary:||Karen Walker's here to see you.|
|Will:||You girls are going to have a ball, braiding each other's hair and talking about boys and doing the Cosmo quiz.|
|Jack:||Oh, you mean, like, "How to tell if your best friend's a bitch?" Yeah, I already took it. You are.|
|Will:||Where are you?|
|Grace:||It's a secret. Now tell me, how does that make you feel?|
|Will:||Like a sorority girl in a bad slasher movie. Where are you?|
|Grace:||Let's just put it this way: the call is coming from inside the house.|
The day you know more about Will than I do is the day I gladly kiss your butt. — Grace, to Jack
I guess in a lot of ways I'm kind of like a younger, much more beautiful version of Leona Helmsley. First, you marry for money, and then, you find yourself loving the old coot. Then he drops dead, and you get the money anyway. It's a win-win. — Karen, on her marriage
|Grace:||Sort these tassels.|
|Jack:||Do you want me to sort them by color? By size?|
|Grace:||God, what is he keeping from me? Oh, my god. It's drugs. It's drugs. He's doing drugs. Without me. Not that I do drugs, but I'd like to be asked.|
|Jack:||You know what else he wouldn't tell either of us? If he's sick. He needs a kidney! Oh, my god. He needs a kidney. Not that I would give him a kidney, but I'd like to be asked.|
|Delivery man:||Just your name, sir. I don't need your phone number.|
|Jack:||Don't be so sure... sir.|
