I don’t think that full-on skinjobs are being created yet, so I don’t think we’re likely to meet one in this flashback. Given the state of the severed limbs we see in the lab (which look like rudimentary attempts to hybridize human parts and robot parts), it seems their research is not that far along. We of course know where they’re going with it, but maybe all that is evident to Adama is that they’re engaged in some kind of human experimentation, which could be motivated by any number of goals. Maybe it’s only when he encounters Leoben in the miniseries that it finally dawns on him what they were up to 40 years ago.
That’s exactly why I don’t think we’re going to see an original human version of a skin job in the flashbacks. Not that RDM is incapable of a dramatic reversal, but it seems like far too big of a revelation to be tossed out in a minisode. Also it would make Adama go from being mildly unperceptive to incredibly dense for not figuring out sooner what the Cylons are up to.
I think it’s the voice of a Hybrid. Maybe the First Hybrid. (It seems reasonable that the development of the Hybrids would have been a necessary transition step to the Skinjobs.) Hybrids also wax philosophical/schizophrenic, and we’re led to believe that Leoben has gotten many of his ideas from listening to the Hybrids. The question is, why/how does Adama hear this voice? It’s after he’s taken his hand out of the mystery fluid, so where is it coming from?
I’m inclined to agree with you, though maybe there are other classes of toasters that we haven’t encountered yet. It doesn’t make sense that humans would have used a one-size-fits-all Centurion design for all purposes. Maybe there was a lab-assistant class of Cylon with more intelligence and manual dexterity?
I’m going to assume that the mystery fluid was exerting some kind of mysterious pull on Adama. What I find stranger than his ill-advised impulse to stick his hand in the tub is that it had an effect on him. I had assumed that only Cylon nervous systems could interface in this way and that the fluid would be completely inert for humans. So either Adama is a Cylon or this assumption is wrong.
This conclusion has led me to some wild speculations. What if the fluid/goo interface was actually invented by human scientists as a way for humans to more efficiently program and control computerized machines, and what if the humans unintentionally transferred their emotions and sentience to the machines though the goo? What if this is what led to the paradox of the Cylons revolting against humans while at the same time being obsessed with transforming themselves into humans?
And what if Adama not only got a glimpse inside the Cylon mind in this scene, but what if they also got a glimpse inside his? Is a copy of his consciousness now a part of the Cylon database? Is that what Leoben meant when he said Adama was a Cylon?
