Sorry, I’m running a bit behind on my recapping.  On this week’s Sarah Connor Chronicles, we finally learn the secret behind those three bloody dots on the wall that have been driving Sarah to distraction …

RECAP DETAILS AHEAD (don’t read if you haven’t watched it yet) …

The secret?  “It’s just a fucking logo, you crazy bitch!”  Or maybe it’s not, but it’s as much as we know for now.  Sarah’s obsession with the three dots leads her to a small start-up company called Dakara Systems, a Japanese father and son operation that’s working on … you guessed it … a new kind of artificial intelligence.  She and Cameron use some deception and play acting to learn as much as they can about Dakara, so that they can “burn it down” before it gets off the ground.  Unfortunately, it turns out the father is deceiving them right back, and he swindles them out of millions of dollars.  Sarah gets the money back, but in the process realizes that her zeal to take down Skynet has turned her into a paranoid nut, seeing patterns where there are none and generally comprising both her and the family.

We finally learn — as many of us have suspected all season — that Riley is not what she seems.  Apparently, she’s been sent back in time along with Jesse by a faction from the future that is alarmed by how much time Future John spends with Future Cameron behind closed doors, because Future John is making bad decisions.  Jesse admits to Derek that the plan is to “stop” Cameron here in the now, arguing that if Cameron and John spend the next 20 years together, Cameron will change what John is supposed to become.  In return, Derek shares with Jesse the fact that he’s John uncle … but Jesse doesn’t tell Derek about Riley.  Meanwhile, Riley is a bit unhinged, particularly after John breaks up with her — she clearly has developed feelings for him — but Jesse gives her a pep talk, and Riley gets her head back in the game, winning John back over again.

Over at ZeiraCorp, Doc Sherman has died as the result of actions that the Babylon A.I. took to protect the resources it needs, and this prompts an internal investigation by Agent Ellison, who learns that during his time with Babylon, Doc Sherman had begun referring to it ironically as “John Henry” — the folk hero — a man who “defeated the machines, but couldn’t stop progress.”  Ellison determines that the doctor’s death was accidental, that John Henry exhibited no malice, and that the only reason it didn’t try to save the doctor’s life is because it didn’t care enough to — it has no ethics or morals to drive its behavior, only procedures.  And the big reveal for the episode is …

That’s right.  Cromartie’s back.  Sort of.  It’s Cromartie’s body, but what’s inside is the John Henry A.I.  Good news for Garret Dillahunt (the actor)!  Not so good news for humanity, though.  Because you gotta figure, this is kind of a fast forward for robot-kind, isn’t it?  In the original timeline, robots progressed to the human cyborg with A.I. stage over decades.  Still, it looks as if the Cromartie body is tethered to that bank of computers — presumably because ZeiraCorp has no ability to manufacture the kind of chip Cromartie used to have yet.  (Look at that picture above, and reimagine Cromartie as a ventriloquist dummy.  I think that pretty much sums it up.)  So there’s plenty of time for the Connors to “stop progress” on this operation before it gets too far.

As Cameron explains, the title of the episode refers to a Chinese game Go — in particular, a point in that game where anything can happen.  It’s a metaphor.
