In this episode, the person of interest was a high school student genius that Finch has to go undercover as a substitute teacher to help. Reese spent the whole episode in a jail cell. The kid was writing a software program that would revolutionize the data compression industry. This episode was different since Finch had to determine if the kid was a victim or the criminal. The storyline was well thought out and it really showcased Finch’s computer skills. Hopefully, Reese will be let put of jail soon so he can start beating people up again.
