Last paragraph:
"…but I’m not sure that it made logistical sense"

Oh - thanks.

I see the poster, and the numbers on it - but the significance escapes me; are these numbers we should recognize from somewhere else in the show?
Would someone in the know care to enlighten me?

Some here have already mentioned but it bears repeating:
the fact that in such a stellar, spectacular, A+ episode that has evertything from humorous banter to dramatic gun fights and deeply emotional character interactions, with all this going on, some of the most poignant and moving moments for me nevertheless where…

In case someone is still reading this thread I would love an explanation because I don't quite see the hidden meaning here.
I believe "Riesen" is pronounced close to "rising" and "Whele" simply like "wheel" - so what, if anything, is this referring to?

What everyone said: THIS SHOW.
Plus: props to Uncle Nolan. John Nolan as Greer is such great, sinister, ruthless, near-demonic presence. His face-to-face with Harold in the last two episodes was just captivating. Whenever they do the close-ups on his withered face - the X-Files Smoking Man has nothing on him - with his…

Okay, I see 2 possible scenarios for who is pulling Collier's strings:
1) The Machine is playing everyone - she actually wants to go public
Admittedly somewhat unplausible, since Harold and the gang have been going up against Vigilance in the past, with the help of the Machine/Root; plus back in 2010, when the initical…

I have to say I am in totally in Adalind's camp. It would be completely understandable if she went on killing rampage.
That was just not okay - stealing her child…

I watched the entire season but apparently I have a very bad memory:
can someone please explain to me why Raylan suddenly is so eager to have a go at Boyd after he hardly paid him any mind all seaon, except as a means to an end?

"Adalind is a goner" - is that a guess or do we know anything about Claire Coffee leaving the show?
I admit it sounds plausible but it would be SO cliché for the mother to die suddenly and unexpectedly… plus what a waste of that whole "Adalind gets her powers back"-storyline.

I am confused:
How much does Fusco know by now? Don't the others basically talk about the Machine openly in his presence already?
At least in one instance, when they are leaving the building shortly after Collier's escape Root and Finch talk about "her" and Fusco doesn't bat an eye.

Okay, that was evil :-)
I hadn't heard about J.J. Abrams fascination with lens flares before…

Someone posted (either here or on io9) that a press release mentions her as appearing next week.

The letter with the supercomputer chip specs had one abbreviation I couldn't decypher:
2200JJs.
GHz, Kelvin and the 2 elements Nb and Si I can understand but what are JJs?
Something to do with energy, as in Joule? Or is it some unit of computation as in TeraFLOPs and the like?
First couple of searches in Google didn't…

No, a cell phone jammer can definitely not kill AM radio; possibly some high frequency FM but still unlikely.
So that's a plausible theory.

Agree to what you say about cellular and bluetooh. About the infrasound: was there some indication of this in the episode?
Interesting idea, anyway.

Okay, that's possible, yes.
I actually thought the phone she destroyed in the doctor's office was his - so he couldn't call the cops on her too soon. But you could be right.

Well, yes, but the voice she hears in the implant still comes in via her phone, so once you knock out cell-phone reception it's over.
Your explanation makes sense only if the "countermeasures" disrupted the wireless uplink from the phone to the earbud but I think what we actually see during the scene in the park that…

Probably a bit of a nitpicky question, but how is it plausible that Decima's "countermeasures" - presumably some kind of white noise interference on cell phone frequencies that knock out reception - work against Root's ear bud but not against her cochlear implant?

The threat assessment Machine graphic at the end of the episode, with all the probablities of fatal outcome in red for Finch ('Admin') and the rest of the crew showed one name that I couldn't place:
"Maria Martinez".
Has she already appeared or is that someone we will be introduced to going towards the season finale?
