Continuity: While speaking to Abrams, Joe mentions that a former spy and friend, Alexander Cartel, had once tried to kill his father, Fenton Hardy. This happened in the episode, "Acapulco Spies."
In the scene where the aide goes into Joe's room to show him the newspaper, it says Tuesday, February 28th, 1979. That is a mistake firstly because there isn't a Tuesday, February 28th in 1979 and secondly because he said his father and brother where to meet the defector on Wednesday the 25th of the same year. The 25th can't be a Wednesday if the 28th is a Tuesday.
