They had a scene together in "The Devil You Know" in S4 as well.

And then, towards the end of the season, it's just one episode per week (Tuesdays)

Blackwell is played by Joshua Close, who did a great job in S1 of "Fargo" as Martin Freeman's brother. I think he can hold his own here.

They mentioned in the season premiere that the shootings happened in a dead zone. That's why they interviewed Fusco to prove that he killed them both, rather than a sniper taking them both out.

I remember in "If-Then-Else" that neither group had access to the bowels of the Stock Exchange. Root and Finch had to play IT support while Reese messed with the cameras on the public floors. This let them into the room to give The Machine access that Samaritan didn't have.

I believe the only thing I will have left will be "Mom" because I love both Anna Faris and Allison Janney. I'd have watched Nancy Drew also because Sarah Shahi but they messed that up too.

I know. Seems they're switching to single episodes per week later, to screw with the show's ratings more. But here is the schedule I have seen for the rest of the season -

Alexa mentioned last week that she misinterpreted the schedule last week, and we would be back to regular episodic reviews starting this week.

Everything's coming up Milhouse!

I like to think it wasn't, because she has had that scene in each simulation!

I loved Ellen talking about how they "rounded up to the nearest million" because there's really less than 100K of them.

It was definitely a big hint when they mentioned it was Root's place.

I believe this episode was slated initially to be episode 7 of this season, and it was moved up to episode 4. It'll be interesting to see how the season plays out and what is changed based on the order it eventually became.

Jonah Nolan has stated that part of the reason Amy Acker was hired was because his wife was a huge fan of "Angel" and it put Acker on their radar. It absolutely wouldn't surprise me if the show has influenced "Person of Interest."

I didn't know that mystery caller from the 911 episode was coming back. It's cool to see the show tie off a loose end like that, especially if it enters into the end game.

From the IGN interview -

I'm just hoping its less revenge and more love!

He certainly learned to wear a vest in dark alleys after Carter.

I wouldn't count "The Danish Girl" as big budget, though. It was specifically an Oscar bait movie.

Root actually got her own set, as the Analog Interface. Those were people who The Machine needed to save herself (aka Root's gang of nerds, Finch, etc). They weren't Relevant numbers either.
