Kate Warner is Jack Bauer's romantic interest in the show's second season. Kate Warner is preparing for her sister, Marie Warner's wedding, only to soon realize that her sister could be marrying a terrorist. Kate investigates further to find out the truth, and hears of Reza's possible connection with Second Wave. Reza attempts to convince her that he has nothing to hide, but she continues to be suspicious, often at inappropriate times (such as when Reza tries to introduce her to his cousin), sometimes sparking conflict between her and her sister. Both her sister and her father defend Reza.
