Did You Know?


There is a flashback along the timeline, but since the Machine is, for the moment, unable to differentiate the past from the present, the moment is designated as "Day R", with the letter 'R' displayed in "Blackboard bold" (a.k.a. "double struck") typeface style, because that is the convention used in Mathematics to denote the set of Real numbers. Real numbers can, of course, be thought of as points on an infinitely long number line. And the Machine is unable to pinpoint the flashback moment's place on the timeline. See more »


While Reese is pinned down by the hit woman he has a phone conversation with Finch. In the conversation Reese tells Finch he is out of ammo and the scene clearly shows his handgun with the breech fully open indicating the weapon is empty. In the next sentence of the same conversation we see the handgun again with the breech closed. See more »

Crazy Credits

The title sequence starts with the usual Harold voice-over, but then the audio and video "glitch" and "crash", symbolizing the malfunctions the Machine is experiencing. See more »

Tows The Line Between Good And Evil
9 May 2016 | by awoolforkSee all my reviews

Its hard to describe this... im trying hard to give a decent but spoiler free review but the level at which this episode operates is great and i mean great! Watching the machine trying to find its way and tow the lines between who's good and who isn't is marvelous. If last week showed us how scary Samaritan can be, then in many ways this was The Machine flexing its muscle also. The cast were awesome, style, experimentation, everything. Episode took the awesomeness from Episode 1 and turned it up even more. This is the best early start to a season the POI writers have ever written.

Everyone go watch this episode!
