Starring: Cliff Curtis, Rubén Blades, Alycia Debnam-Carey, Mercedes Mason
Continuity mistake: When Althea and the MRAP first appear in the show, we learn that it has a kill switch that is disengaged by using various switches in the correct order. However, later in the show the MRAP is stolen several times by various different characters. There's no way these characters would've known the procedure to bypass the kill switch, and given how obsessed and protective Althea was over the MRAP, it's extremely unlikely that she kept the start up procedure written down somewhere inside it.
