Person of Interest, Season 3

Root:
So, you see, sadly, I need to be moving on.

Ronald Carmichael:
Okay. So, um, you're going to escape? Hmm. And how do you plan on doing that?

Root:
First the phone on your desk will ring. She'll be letting me know it's time. Then I'll punch you in the carotid artery. It'll hurt, Ronald, but it won't kill you. Then I'll take your car keys.

Ronald Carmichael:
And the guards, how how will you manage them?

Root:
I won't have to. They'll be incapacitated from the desflurane in the ventilation system. It vaporizes at 75 degrees. Which the building climate control has been programmed to reach ten minutes ago.

Ronald Carmichael:
Okay, this voice that you hear, she is she's gonna do all this?

Root:
Of course not. She sees everything, but there's very little she can do about it herself. That's where I come in. She tells me what to do and I do it. Well, she did help me a little with stealing the desflurane from the automatic dispensing system. Don't worry. I closed the vents in your office two days ago. It should have cleared out by now. Do you hear how quiet it is out there? Must be almost time. Are you as excited about this as I am?
