Asher Millstone calls Connor Walsh "Waitlist", since he managed to return to law school after he was kicked out for low grades; this is a reference to the nickname that Connor gave Wes Gibbins for being accepted off of the waitlist.
The title along with the writer, director, and filming dates were all revealed when creator/director Peter Nowalk posted a picture of the first page of the script of the first episode of the fifth season on his Instagram story.
Rome Flynn, Amirah Vann and Timothy Hutton have been added to the main cast. The latter will receive the "And" credit.
The episode title is said by Gabriel to Frank.
