The episode title, music- kind of fitting really. In a sense, every just "went away"…Elias, Root and, finally, Harold's stringent adherence to a scrupulous nature.

You made a very important point. The first instance of Finch's darker side did indeed appear in Beta when he said "if they harm her in anyway…kill them all".

Now that we know Root is dead and the Machine adopted her voice, the voice-over intro to B.S.O.D. comes to mind. It is the Machine speaking to anyone who's listening.

Probably Michael Emerson is in a league of his own…too good for Emmy's and Golden Globes.

Emerson has enough 'feelsy' moments in this season alone to win an Emmy and a Golden Globe. For some reason, his performances are being constantly being passed under the radar.

Remember a few episodes back, there was a bit of foreshadowing from Elias…something like "the quietest ones are the darkest in heart" or something similar. That, the events in Sotto Voce and the loss of two of his comrades have changed Finch. Now we get to witness his descent into darkness.

Bummer!

There's not enough time. And even if she resurfaces, it won't be satisfying since there isn't the time to show what happened in the interim. Had there been the usual 24 episodes, the season could've better shown the escape efforts of both Shaw and Control.

All they need now is for Control to resurface (somehow). But there isn't enough time for that to have a satisfying storyline,

One of the greater problems of a shortened season, as I've found watching the last three episodes, is the inchoate nature of the storylines. 'QSO', 'Reassortment' and 'Sotto Voce' try to contain three stories, which some might find a little unsatisfying precisely because of the lack of screen time. But, in all…

Also, Elias referred to Harold as "friend".

The intro and outro sequences of this episode really resonated. Moreover, I was hoping to see when Finch would finally give in to his darker side.

NCIS: Baghdad was a nice touch! :P

Yeah, they were all thinking about loved ones: Finch was thinking about Grace, Reese pondering over his lost chances with Jessica (and possibly Iris) and Root still in her quest to find Shaw.

The eugenics bit was terrifying. I agree with Samaritan's Machiavellian proclivities, but this is evil!

That was a priceless moment in terms of the show and really sad.

While "A More Perfect Union" was a rather bland episode (number-wise), there were some terrific moments: Finch singing "We're not gonna take it", his moment with Root during the dance where he expresses his concerns over whether they themselves are capable to making the right decisions faced with the possibilities of…

I really liked Elementary during the first two seasons. The first had the Moriarty arc (who doesn't love Natalie Dormer?) and the second one had the whole thing with Mycroft. I began to lose interest from the third. The fourth featured John Noble, which is great, but didn't really pull through all of it. Again, the…

In my heart, I always knew Elias would live. He wasn't shot fatally like Dominic. Also, I happened to come across some leaked photos from later episodes which showed Elias with Finch, which got me thinking.

I second that.
