Speaking of Alias (and we were, a few items ago), the show is now free to use Amy Acker  so deliciously wicked as Kelly  as much as it likes. The Angel alum has been replaced on CBS' mid-season series, The Unit, with Audrey Marie Anderson of Once and Again. Coincidentally, Acker was to have played the wife of Scott Foley, real-life ex-husband of Jennifer Garner. On second thought, maybe that's not coincidental at all.
