The next number the Machine dispenses to Finch and the team belongs to Cyrus Wells, a custodian. His current blue collar job belies the fact that he has an MBA and was once a multimillionaire. What they also quickly learn is that the person who may figuratively pull the trigger on Cyrus, the target, is Root. Finch learns directly from Root that she has her own Machine-driven mission with Cyrus, her tasks (unlike Finch's) are laid out for her by the Machine immediately before she is to carry them out. All Root knows is that her overall goal is to protect the Machine, most specifically now from a competing Machine, namely Samaritan, which is close to being functional. Finch and Root will have to figure out if their Machine-driven tasks are incompatible, especially as Root has demonstrated in the past that the death of someone like Cyrus is acceptable collateral damage.

When Finch is reading the precautions for the Helium to be delivered to Maxwell Ltd., it refers to the handling of compressed Helium (at room temperature). He tells Reese, and we later see, that there is liquid Helium being delivered. Liquid Helium is at -458°F and requires much more stringent handling procedures. See more »


Root: I heard you skipped breakfast, and you and your Australopithecine coworker can just take the day off. I've been doing just fine without a safety net.
Sameen Shaw: Look, the only reason you're not stuck in a cage right now is me. Don't make me look bad.
Root: I couldn't make you look bad if I tried.

One of the very best POI episodes
19 February 2018 | by bassmanproSee all my reviews

I don't know who exactly had the idea of creating the Root character, but whoever this is, this person is a pure genius. Though I loved the show straight from pilot, I found it even much more interesting when Root was introduced (then gradually became on of the main characters).

This episode is focused on Root. Her major action is what is happening today and regarding tomorrow's threats, but also her past. The richness of this episode still blows me. It could have been directed by Mr Spielberg : there is EVERYTHING in this episode : (much) fun, (much) action, redemption, danger, violence, intelligence, strategy, etc.

It's in this episode one may realize that probably no actress except Amy Acker could have impersonated Root in this show. She acts it awesomely, at a point when one may wonder where does Amy stop and when does Root begin. She plays so naturally.

Great, great, great episode, including the starting point of a huge danger that is coming. This episode can be watched standalone if you didn't watch the previous episodes and seasons, but of course, having watched them will help understanding the subtle elements.

Producers : please bring POI back to life !
