Karen's step-daughter Olivia visits her for Christmas, but Karen wants to get rid of her as quickly as possible so she makes Jack take care of her. Other than expected, Jack has a lot of fun with Olivia and Karen suddenly wants to hang out with them. Grace starts to get along with Will's mother pretty well until she ruins her favorite figuring. But since Marilyn doesn't know about it neither Will nor Grace tell her about it. The guilt over not telling Marilyn drives Grace nuts.
