It is pretty obvious Katherine was dropped from the show, and both she and Rhimes have spoken about the reason for that (i.e. Katherine's statement regarding the quality of writing). I haven't found anything to suggest she stopped showing up for work being the real issue.

Izzy's character was dropped. I don't think it would have happened had their relationship stayed intact. While I think it is acceptable that a person would just leave, although she had her reasons, that is no reason why Izzie couldn't be mentioned in regard to what she is doing now. It is a topic I see many fans of hers talking about.

Katherine is happy to return, but Rhimes still doesn't even want to say a little thing about any achievements the character has made, which many characters who have left are given.
