That puts it during the Thanksgiving/Christmas season when many other shows will be in rerun. The official word:
NIKITA will wrap up her mission with a final six-episode run beginning Friday, November 22, 9:00-10:00 pm ET on The CW, airing over six straight weeks.
Framed for assassinating the President at the end of last season, Nikita (Maggie Q) finds herself at the beginning of season four alone and on the run, hunted as the most wanted woman in the world. But when she follows up a lead that could clear her name, Nikita unexpectedly finds herself reunited with her old team. Forced to work together again, Nikita and her allies have to get past their emotional wounds in order to take down their nemesis, Amanda (Melinda Clarke). In the process, they discover that the plot to frame Nikita is actually part of a much larger conspiracy, one that could lead to global catastrophe.
