Negan's wife Lucille is played by Jeffery Dean Morgan's real life wife, Hillarie Burton.
It's revealed that Negan's last name is Smith.
This episode reveals that the current series is set in the year 2022.
When Lucille drives away after hearing the news story she switches the station to one playing the song "Partytime" by 45 Grave from the movie The Return of the Living Dead (1985).
When Lucille turns on the radio in her car, a voice says, "the killers are eating the flesh of their victims." That line is right out of 1968s Night of the Living Dead, the first film to have zombies eat the living, without which, there wouldn't be The Walking Dead.
