Jimmy overcompensates for his previous paternal failings by letting his kids throw a party. Knowing Diana would disapprove, Jimmy agrees not to tell her and keep her away on party night. Under the pretext of seeking advice on matters 'too personal' to discuss around the kids, he invites her to dinner. At Diana's favourite restaurant, Jimmy discovers that while he and the kids have been sneaking around behind Diana's back, Diana has been sneaking around theirs.
