It's zero hour for Person of Interest.

In Finch's eyes, Samaritan has had Team Machine on their back foot for far too long. Root's (Amy Acker) death was the last straw for the techie recluse, and Michael Emerson's character is ready to go on the offensive. His plan, however, could eliminate more than the Machine's Orwellian counterpart.

"Out of his fear and his anguish and the sense of hopelessness and loss, Mr. Finch ... doubles-down and finds a solution that is terrible to him in his heart," Emerson said, according to TV Guide. "When no other solution is available, even the roughest-looking idea, you may have to go with it. There's no more time. He runs out of time. He has to do something."

Finch ended "Synecdoche" by stealing a computer virus, and, as ".exe" and "Return 0" play out, that bit of code could do a whole lot of damage. When the finale ends, however, fans are sure to be satisfied.

"We went out in a way that I'm proud of," executive producer Greg Plageman told IGN. "When you get over 100 episodes on broadcast television, it's very difficult to sustain a larger narrative, a bigger story, and then finish it off in a way, because you rarely get the notice that this is the last season. And [series creator] Jonah [Nolan] and I made the decision at the beginning of the year that this was probably it; we should write to that."

Tune in to CBS for Person of Interest's final two episodes on June 14 and June 21 at 10 p.m. ET.
