In the 183rd episode of the show (Season 8, 6:00 am – 7:00 am), Chloe surpassed Tony Almeida (Carlos Bernard)'s episode count of 115, becoming the character who has appeared in the most episodes of the show other than Jack Bauer. Perhaps appropriately, just after 8 am that day, Chloe is promoted to (Acting) Director of CTU, replacing Hastings. This puts Chloe in an abnormal position in regard to Jack: normally she helps him carry out clandestine operations in defiance of their mutual boss, but now she is the boss he is defying. This new dynamic is put to the test within two hours of her promotion, when Jack steals a helicopter to pursue justice in direct defiance of orders from President Allison Taylor (Cherry Jones). Chloe sticks with the responsibilities of her position, ordering pursuit instead of supporting Jack; this is the first time in several years the two have pursued clashing goals.
