> I wanted to acknowledge a worthy opponentThe latest number is Scott Powell, an unemployed construction manager who has sent threatening emails to a congressman and obtained a rifle license. Reese and Finch believe he's planning to assassinate the congressman at a public event in the city, but when Reese tries to intervene at the last moment, they realize the shooter is someone else entirely: Powell is a patsy, set up as the assassin by a computer hacker. With the evidence against him, Powell is arrested by the FBI, forcing Reese to intervene and break him out of custody, which kicks off a city-wide manhunt. Finch attempts to locate the hacker who set up Powell — a woman who goes by the name "Root" — but she reverses the trace and starts destroying Finch's systems from the inside-out. To prevent Root from compromising everything, Finch destroys his set-up at the library and orders Reese to destroy his cell phone before going mobile with nothing but a laptop.While Reese and Powell evade the shooter, who is determined to clean up the final loose ends, Finch calls in Zoe Morgan to help figure out who hired Root and the shooter to kill the congressman. Together, they're able to gather evidence on the congressman's business partner and forward the information to Carter while Reese dispatches the assassin and Powell turns himself in to the FBI so he can be exonerated. After Powell returns to his family (With Finch hinting that Powell may be contacted by a construction company he owns that has a foreman job opening up in the near future), Finch is contacted via IM by Root: she knows his real name, acknowledges him as a worthy opponent, and looks forward to "the next time".

Tropes present in this episode include:
- Brick Joke: The womanizing student Finch meets at the library gives him the thumbs up later on, thinking he's scored with Zoe.
- Chekhov's Gunman: See the background FBI agent overseeing the investigation into the congressman's death? That's Agent Donnelly, and a few episodes down the line, he will become quite important.
- Combat Pragmatist: Reese rips a hand drier out of a bathroom wall and gives Root's gunman a concussion with it.
- Conspiracy Thriller: The episode.
- The Cracker: Root.
- Cut the Juice: When he realizes that his system has been compromised, Finch simply destroys his phone and turns off the generator powering his equipment.

- Fall Guy: Scott
- First-Name Basis: Used to give Harold Finch an Oh, Crap! moment.

- Ikea Weaponry: Subverted; Powell is assembling a confetti-firing cannon.
- Kinda Busy Here: The episode opens with Finch at the library pouring tea, then ringing up Reese to wish him a pleasant "Good Morning".

Reese: I'm working on it.
