If there were these two follow up seasons of this show, then this is how it goes:

Season 7 begins with a new member, an African-American woman, replacing Cassidy, who quits SIU to travel to France.

Cassidy attends a new college in France and meets a new boyfriend there.

The season ends when Harvey got killed by an explosion.


Season 8 begins with another new member, an Asian-American man, replacing Harvey.

Cassidy and her new boyfriend graduate and then decide to get married.

The season and series end when Nash retires from the SIU, succeeded by Joe, and Nash and his father, Nick, travel to France and attend Cassidy's wedding.
