What happend to Alison

Sadly I missed the three last episodes of KH.
All I know is that Kevin lost custody of Sara and that must have been a real tearjerker.But what happend with that weirdo Alison, Dames secretary? The last episode I saw she was working in Dames new firm and I remember they had a party at the firm and she looked very jealous when she saw Dame and Veronica hug eachother.She seemed to be a bit nuts,anybody who remember what happend to her?
