chunk: Allie advertises for a new roommate to share her apartment in the Ansonia. She eventually settles on Hedra Carlson (Jennifer Jason Leigh), whom she nicknames "Hedy", and they become friends. Hedy tells of how she was supposed to be a twin but her twin was stillborn, leaving her with a constant feeling of loneliness. After a few weeks, however, Hedy becomes overly protective of Allie by erasing Sam's voice-mail asking Allie for a reconciliation. Later she buys a puppy that she names Buddy to bond with Allie. Hedy soon becomes jealous and upset when Sam is able to win Allie back.
  Allie and Sam seek a new apartment for themselves. On their way back to Allie and Hedy's apartment, Allie is horrified to see that Buddy has fallen to his death from the balcony. Angry and upset, she accuses Hedy of leaving the window open resulting in the puppy's death. However that night while comforting a distraught Hedy, Sam tells her that "if anyone's to blame, it's my fault."
