hey! I've been watching grey's for the first time by watching the episodes online. I'm now on like episode 7 or 8 of season 4 and I haven't missed any. HOWEVER where
the heck did addison go? I mean, she hasn't been in like the past 10 episodes I've watched. did I miss the explanation of where she went? I saw the two-parter episodes that she went to LA but then she came
back and was back. I never noticed a mention of her leaving again. So did I miss an episode I don't think I missed?
