In Betty's dream, she goes into her kitchen to find her mother tending to the head wound of a black man sitting at the table. This man is supposed to represent Medgar Evers, a civil rights activist and field secretary for the Mississippi NAACP who had been instrumental in the tumultuous 1962 desegregation of the University of Mississippi. On June 12, 1963, Evers was assassinated in his driveway in Jackson by a Ku Klux Klan member named Byron De La Beckwith. Although the murder was a national outrage, De La Beckwith was not convicted until 1994. When Don and Betty met with Sally's teacher the day before, the teacher mentioned that Sally was asking about Medgar Evers' death, which is why he was in her dream.
The scenes between Don and prison guard Matt - both men waiting for their children to be born - took up over 9 pages of dialogue and were all shot in one day.
Action takes place from June 20th, 1963 until June 22nd, 1963. Eugene's birth certificate states that he was born in the early hours (4:53 am) of June 21st, 1963.
In the previous episode, Sally's dad Gene mentions that Betty's like her mother in defending the maid, who is African American, which makes the dream scene in which her mother's helping the slain civil rights activist Medgar Evers more clear.
