Sources confirm that a major castmember - a series regular - is on the way out. [...] The actor in question will exit the series in a dramatic fashion. I might even go so far as to call it a major freakin' twist, the repercussions of which will be felt well into next season and, perhaps, beyond. One thing I feel reasonably comfortable letting you know is that the aforementioned twist does, in fact, occur this season - i.e., sometime between tomorrow night's post-strike return and the season finale in May.
