In a subsequent interview with the object of her affection, Jim tells the camera crew that he thinks she is "crazy".
However, in "Last Day in Florida", it appears that she may no longer care for Jim, as she laughs along with Dwight when Dwight repeatedly insults him (although, it is also possible that she was only doing this because Dwight was Vice President to Nellie Bertram at the time).
