Michael Emerson, talking to himself in public with aplomb.

There's also the end of Q&A, when Greer's getting into business with Fetch and Retrieve, after the company's search algorithms led a man to suicide.

Root even had one in Skip ("Flag on the play, Harold").

Another strong POI writing debut. Among many great lines, my favorite is this one from Finch: “There’s no way to keep the victim safe if the perpetrator is Samaritan.” Directly, it encompasses the times when the team have dealt with people and places getting special attention from Samaritan. Indirectly, I think it…

I take it to mean the episode is strong enough in its own right. These aren't rankings.

I agree that Khan's great, but my other favorite is Walter Dang. In hindsight, I feel like Simon wasn't given enough focus, that he didn't really stand out in the midst of the plot. It's a tricky balance, though, tying a case of the week to the larger story.

First, Root looks awesome in shades. And speaking of which, she and Finch have been through many tonal and moral shades this season. Their interaction in this episode, as in “Prophets”, surprised me in how serious it became (the intensity between these two is crazy). It's cool to see more of the cloak-and-dagger…

The episode could be considered setup in the grand scheme, but I think its structure nonetheless makes it very solid and enjoyable. It’s one that feels especially like a ride, the way it weaves through its set pieces, and so lends itself well to repeat viewing. It’s a flow that holds attention in each scene and…

Iris, too.

I don’t know to what extent Finch was playing the game. Part of me thinks he may have tipped off the security guard, or told Fusco to do so. In any case, Finch was played, but as he told the Machine: “Mind you, you’ll encounter far more capable opponents than me, if you go looking.” He was true to his humanism, on…

Claire was under the impression that the sniper WOULD miss, which would've been even more conspicuous.

David Slack tweeted that Guilty is the first episode of the series to include not a single gunshot. It’s a nice bit of trivia that, I believe, also underlines the episode’s place within the larger story. Whereas Control-Alt-Delete is a shift of perspective, this is one of scale. Whereas the early scenes of The Cold…
