Character mistake: When Samson is playing trivia with Cross' kids right at the beginning of the episode, he asks, "First black mayor of D.C.?" and the son answers, "Marion Barry." John awards him the point while his daughter asks, "Who?" Not the first black mayor of D.C., for sure, since that was his predecessor, Walter Washington. (00:03:30)
