When to Watch: Friday, May 17 at 8 p.m.What to Expect: Nikita's season-finale title? "'Til Death Do Us Part." Yay! Not so yay? The whole death thing for Michael (Shane West) and Nikita (Maggie Q) might come in that episode as Nikita is forced by Amanda (Melinda Clarke) to choose between saving herself or saving Michael. Party pooper!
