You know, I actually like what they're doing with Chloe. The fallout over the events in season 8 must have been gruesome. For years, knowing that the government was hunting Jack, even after all the good he had done, how the sacrifices he had made in the name of protecting innocents didn't mean anything to people in power. She's not a violent person, she wouldn't take up arms in the traditional sense, she'd use her brain to do damage. While I find it quite questionable in the real world, in the fictional world of 24, it makes logical sense.
