David invites the other couples to a charity ball he and Karen are attending, where Jenny lets off a fire extinguisher over Natalie (Lorelei King), David's boss. Natalie demands compensation and a written apology from Jenny, putting David in a difficult position. Rachel tells Karen that she is pregnant but does not know whether the father is Adam or Kris, whom she slept with when he was staying in Manchester. Adam proposes to Rachel, thinking he is the father, and is distraught when he learns he may not be. Rachel decides to move to London until the baby is born, and Adam follows her to the station, imagining a Brief Encounter-esque reconciliation. He tells her that he does not care who the father is. Rachel proves that he does care and leaves anyway.
