Only the second time Stephanie March (Alex Cabot) and Diane Neal (Casey Novak) appear in the same episode since season 3 episode 10 Ridicule (2001) where Diane Neal was not ADA Casey Novak, but on the other side of the courtroom as Amelia Chase.
This is the first time in which a former ADA and the current ADA appear in the same episode, in this case Alexandra Cabot and Casey Novak. It happens four more times in the series between seasons ten and nineteen.
The two women in the opening scene talking about a TV show are referring to Desperate Housewives (2004).
Alex Cabot's date of birth is May 31st, 1966 according to the information on the computer screen next to her picture.
