Greene is diagnosed with a terminal brain tumor, but is given hope of a reprieve though, when Greene finds a surgeon in New York who can remove the tumor.Corday accompanies Greene to New York City and is present in the operating room for the procedure, by his side all the time.This is a particularly trying time for her - she has to adjust to being at the bottom of the heap after enjoying so long at the top, and on top of that she is supervised initially by Dale Edson - described even by Romano as a weasel.

In season 6, Corday saves the life of serial rapist and killer who starts to engage her in a series of mind games.
