I think the creepiest part of this episode wasn't that John was turned to stone, it was that he was aware of everything that happened to him.
Can you imagine being decapitated and then tossed around and thrown into a vat of acid, only to be rescued by freaking Scorpius? Totally frelled up, if you ask me. During the entire sequence where John was decapitated, I kept trying to imagine what he was saying. The crap coming out his mouth would've been a hilarious voice over. All the acid stuff was pretty gnarly. We not only got John's disembodied head floating in it, we also got Chiana being hung above it, John threatening Scorpy with it, and Cargn getting kicked into it by Crichton. (I guess turnabout is fair play, since Cargn was the one that threw John's head into the acid first.) The one thing that bothered me more about the whole thing was, did John really have to show Scorpius mercy? I literally yelled at the screen, "Just kill him!".
I didn't quite buy Jena not killing Crichton, once she realized he wasn't actually a Peacekeeper spy. However, I did like what her actions said about individual Peacekeepers. As a whole the Peacekeepers are a merciless, monstrous, and fascist presence that easily parallel every nasty Imperialistic government ever to exist. Yet, the people once divorced from that indoctrination are as capable of compassion and mercy as anyone else. So although I thought their relationship was a bit forced, I liked Jena as a character. At the same time it bothered me that John slept with her, even though she was a gorgeous alien spy and the Kirk in him was totally overwhelmed by his libido. To me it felt marginally like he was cheating on both Katralla and Aeryn. So he totally lost points with me there.
John's daughter will at least be raised by two good people (Katralla and Tyno). She'll also be rich, powerful, and the future ruler of millions, so that's something. But for John to lose family like that, literally the only biological connection he may ever have for the rest of his life, must've been devastating. Which is why the end of this episode was so significant. Not only did the reveal that John and Aeryn are biologically compatible give this entire trilogy meaning, it also allowed Crichton to hope that a real family could be in his future.
For Aeryn, the way I interpreted her smile after they kissed using the genetic drops, was that she fully turned away from her Peacekeeper past, and embraced the idea of being irreversibly contaminated. Which I think was the whole point of Aeryn's sojourn into the wasted lands. It was all a trial of pain so that she could work through her feelings -- falling off the rock wall, breaking her leg, dragging a dying Dregon across the desert, and ultimately coming to realize that the potential pain of emotional risk was worth it. I guess for her character it was an important journey, since it was pointed out that she was trained to kill, not to feel. She grew up in a society that shunned emotions, that actually killed or imprisoned people for having attachments. It's easy to forget her journey isn't a simple one.
With all that other stuff, the Moya/Zhaan subplot is a little forgettable and ultimately irrelevant. It turned out that Moya being decommissioned was just a ruse to figure out if Zhaan was good enough to protect the galaxy from Leviathan gunships. That seems convoluted at best, but I suppose it makes a bizarre kind of sense. I'm not sure it fits though, because in Zhaan's rage over the Builder killing Moya, she tried to kill him. That doesn't strike me as a particularly good trait to base their decision on. Or should I look at it another way, that she was willing to kill to protect Moya? I don't know if I can buy that logic, but the Builders are an advanced alien species, so maybe they don't have the same values that we do.
The Builder looked like Londo from Babylon 5, even though his makeup more closely resembled a Minbari than a Centauri.
Clavor really got what he deserved. It also showed that Scarrans are much like the scorpion that asked to cross the river, basically never trust them because their nature is to deceive and kill.
So Scorpy is immune to acid? Damn, either he's really bad ass, or his suit is.
D'Argo's sympathy for John was also a really nice touch, reminding us that he lost his own son.
So those blue rods that we've seen Scorpy put into his head are designed to balance his physiology. As half Sebacean, he is vulnerable to heat. With his Scarran side, he is at home in the heat. So he's literally at war with himself. No wonder he's so vile and hateful.
I loved Scorpy and D'Argo's conversations. They were noticeably missing from the second part of this trilogy. I thought that they had a nice bantering chemistry.
John: "Well there you go, good guys win for once. And I have a child that I'll never know."
D'Argo: "I cannot find Crichton's head anywhere."
John: "How Batman was that!"
Tyno: "Crichton, where are you going?"
John: "I don't know. I'll let you know when I get there."
Okay, this was a flawed story, contrived to bring our main couple (John and Aeryn) to a very specific place relationship-wise. Still, as a bridge from a 'will they won't they' to a full on romantic story, it wasn't so bad. There was more than enough good to outweigh the tedious and bad.
2 1/2 out 4 Holographic children for the whole 'Look at the Princess' trilogy.
