This usually light USA Network series has begun Season 3 trying to darken the mood a bit, adding more credible danger to the mix, and complicating CIA agent Annie Walker’s relationships within the agency as well as in the field. Piper Perabo (pictured) stars – but has many scenes stolen by supporting cast members (Christopher Gorham, Kari Matchett, and now new arrival Sarah Clarke, for starters), so watch for that. It’s not treachery. Just talent.
