Honestly, I don't think an editor's going to do it. Within the first two episodes, you have the beginning and end of the season - October 2nd and November 8th respectively - mapped out, and you have a timeline of three weeks from the first episode to the ninth, leaving only two weeks to get from the ninth episode to the twenty-second. So I can totally understand why later episodes contradict that timeline; in my opinion, it isn't the later continuity lapse that's the problem, but their original timeline. After that, you can go one of three ways: employ some of that neat space-time continuum bending and go back and actually plan this stuff in advance, stick to the original timeline and end up with something that sucks because you were forced to rush it, or ignore continuity and just do whatever the hell you want and hope nobody cares too much, which is what they seem to have done. And honestly, I don't care too much, but time is such a big theme/plot throughout the series that I just wish they'd sat down and planned it all properly from the beginning.

(And honestly? The shows that I love now, I love them, but man do they have some bad continuity. I honestly don't remember anything on Buffy being this blatantly erroneous, and I can't believe that it actually seems wrong now, somehow, for a show not to have massive continuity errors. Man, I miss the days when the continuity editor's job was something other than, seemingly, editing out anything that might be mistaken for coninuity.)
