Television critics have expressed differing opinions about Christy's story arc with Billie. DVD Talk's Jeffrey Robinson felt that Billie and Christy were the strongest parts of the season, and Sheldon Wiebe of the entertainment website Eclipsemagazine.com regarded the characters as re-establishing a "dark undercurrent" reminiscent of the show's first and second seasons. Shawn S. Lealos of CHUD.com agreed that Billie and Christy's story was the highlight of the season, but asserted that more screen-time should have been given to properly develop Christy's character.
