The last four years have not been kind to 24: Live Another Day's Chloe O'Brian.

As viewers learned in the event series' premiere, more than just Chloe's appearance has changed since her days as a CTU analyst. On Monday's episode (9/8c, Fox), we'll find out exactly what went down when Chloe (Mary Lynn Rajskub) tells Jack (Kiefer Sutherland) the heartbreaking truth. An added bonus: Chloe's confession also begins to thaw the icy dynamic between Jack and his former sidekick. 

24: Live Another Day: Is Jack Bauer the hero or the villain?

 But the special moment doesn't make their relationship 100 percent whole. In fact, even though Jack makes it clear to Chloe that he can't stop the assassination attempt against President Heller (William Devane) without her, it's ultimately Chloe's choice whether or not she will continue the mission. Fortunately, Chloe is still on board... for now.

"They do care about each other, they do trust each other," Rajskub says. "She's very angry, and she doesn't want to do it. But there is a part of her that doesn't want to let him down, and she's going along with it, even though that's not really where she's at. But there is a question mark."
