Winston and Guerrero have forgotten more about Christopher Chance than we'll ever know, but the only person fully aware of Chance's capabilities is the man himself. And that's what worries our hero when a visiting foreign VIP is in grave danger tonight: The would-be assassin is Chance's former protege. In fact, he's so concerned that he taps FBI agent Emma Barnes (Emmanuelle Vaugier, from the episode "Embassy Row") for help in stopping him. (Oh, and maybe he's just a wee bit attracted to her, too.)
