Here's a non–news flash: Jack Bauer (Kiefer Sutherland) is about to have another lousy day. This time the 24 clock will be ticking in the United Kingdom, where political unrest propels America's favorite absentee antihero into action. (Fox's 12-episode season won't document every single hour of the day.) Naturally he's going to need his requisite wing (wo)man, Chloe (Mary Lynn Rajskub). Just don't expect the same eye-rolling smart aleck we loved for eight seasons. After Jack supposedly went off the grid in the 2010 finale, Chloe ended up joining a WikiLeaks-type organization in London. ''I'm more hardened,'' Rajskub tells EW. (William Devane and Kim Raver will also reprise their roles for 24: Live Another Day, premiering May 5 at 8 p.m.) ''I've seen more of the world. When you pick up with me, I've completely turned against the government.'' So that explains the moody makeover? ''It's a very dark, very damaged look,'' explains Rajskub. ''It's a bit of an FU to the world.''
