In the FEMA Detention Center, there is an email in one of the computers titled "Clean up of parking area." After the body of text, there is a postscript: "P.S. Episode 9 tonight? If so, let's go early. I hate standing in lines." This is possibly a reference to the rumored continuation of the Star Wars series with a new trilogy of episodes numbered 7-9 set to take place after the original trilogy, as well as a nod to the fact that Star Wars movies always have long lines on opening weekend.
