After Jack Bauer, Chloe O'Brian is 24's most notable character, and one with great significance to the fan base, thanks to her infamous attitude and demeanour. Many consider Chloe (played by actress Mary Lynn Rajskub) to be the heart and soul of 24, even if she wasn't involved with the show until season three. Chloe's role in the show has shifted and varied many times throughout her six season run, but she continues to be the sole character that without a doubt all viewers know for certain is not a traitor to her country, friends, or duty. Chloe appeared in 125 episodes of the series, and has been named one of the greatest hundred best television characters of all time by countless polls. For reasons unknown, Chloe is coming to 24: Live Another Day with an entirely new appearance., though producers have hinted that it could be in reference to ongoing turmoil in her life as an effect of a tragic loss.
