Fantastic season finale to what has been some of the most entertaining TV I've watched in a long time. Still in shock that this was produced by SyFy! I thought they did pretty well with Dark Matter and Killjoys last fall, but The Expanse is on a different level altogether. I hope this is just a taste of good things to come from the network, I've missed good Sci-Fi on TV in the last decade.
I really enjoyed how this episode opened. It basically ran through everything I'd summarized/theorized earlier in the thread, acting as both a "previously on" segment and filling in some minor gaps in the story and continuity. It also helped set the stage for later events without a ton of exposition needed, as we quickly learned everything we needed to know about the proto-molecule from watching Julie's story unfold. I assumed the lasers were to feed the proto-molecule the energy it needed to grow, just as the radiation burst was for the newly injected folks. It looks like the scientist guy and his mercenaries are trying to turn the station into a giant nest for the proto-molecule, to see how it will adapt, grow and evolve. The only thing I can't figure out is WHY? It's not like they can control it, or even communicate with it, unless maybe scientist guy is thinking if they grow it big enough, perhaps they can communicate with it. That could be what it was trying to do with cyber-spy guy before deciding just to absorb him instead.
The only part of the whole thing that struck me as kind of dumb was that the bad guys were working for Earth-based people, with the knowledge of the UN version of the CIA, and somehow were still stupid enough to use engines that could be traced back to their manufacturing origin. I know they killed the UN woman's friend and tried to set it up so that it looked like he stole and supplied the engines, but it's pretty weaksauce for the level of game their playing everywhere else in the universe....
Bummed that it will be 2017 most likely before we see any more.
