[Spoiler] The old man with the tomatos IS Gordon Rosewater, founder of Paradigm Corp. However, he apparently IS really going dotty – maybe as a result of the mental trauma of having had to set all this up.
Rosewater apparently was behind the big cataclysm involving the Megadeuses being used to bring about the downfall of civilization, and took on its reconstruction. The disaster apparently involved a war in which the Megadeuses were the primary weapon. Included in the process of the reconstruction, ostensibly, were the “tomatoes”, a set of persons apparently cloned from those alive at the time of the disaster, who were preprogrammed with latent memories for later call-up – such as Roger, who apparently can remember significant flashes from 40 years ago.
One key part about the Megadeuses is that a “true” Megadeus (such as Big-O or Big-Du-O) DOES have an intelligence and can to a point make a choice about what person it will synch-up with. The synchronization is not purely mechanical but apparently partly psychic/neural (more on this in Season 2). Thus Big-O’s login message: “Cast in the Name of God, Ye Not Guilty” actually DOES mean that Big-O “reads” that Roger is a “good guy” and worthy to pilot.
As you are aware, there are TWO “seasons” of Big-O, the second one of which was created in response to US-market demand after the first run of the cancelled-midseason original. At the end of the First season this is as far as we get, so here’s a spoiler box for the rest[/spoiler]
[spoiler] Most of the 2d Season is a Grand Misdirection, but a sometimes really wonderful one. But you wanted spoilers so here it is: In the last 3 eps we learn Rosewater’s reconstruction of the ruined world is a “Matrix” or “Truman Show” type grand simulation, put in motion not with the helpo of the original Waynerights and the clone-sources for Roger Smith and other characters. We also get the hint that many of the population may not even be clones, but mere sims – after all, in VR what’s the difference?
This world is complete with a shadowy “external enemy”, the Union, presumably representing another civilization surviving outside Paradigm, of whom Angel is supposed to be an Agent. However, it seems she’s one of the tomato-children, a clone/sim avatar of an original Angel, inserted into the world of her own creation w/o knowledge of her true identity. The Union though are just as set-up as everyone else – when a Union agent attempts to take over a Megadeus, the screen flashes: “Ye Guilty” and the agent is absorbed.
First to discover this is Schwarzwald!
However, the system has become unstable. There are suggestions that this is due due to the effects of latent memories being activated at the wrong times, attempts at free-will action of some of the players, and that it just stores 40 years’ worth of data – that is, that the disaster may or may not have happened 40 years ago, but it may be that that is as far back as everyone’s simulated memory extends, i.e. the disaster ALWAYS happened “40 years ago” no matter if this is really year D + 18, 19, 39, 41, 50 or 600! This results in ever more frequent paradoxes (such as Dastun meeting a woman that was in a movie he saw as a child and replaying the death scene himself) the system can’t resolve seamlessly.
Alex Rosewater, current CEO of paradigm, who may be the real son of Gordon or may himself be one of the clone/sim tomato-children, has an imperfect notion of wwhat is happening and is setting things up to take back control of the system and reshape it “right”, as it were. The Union has an ambiguous “Cold War” relationship with him on that – each is trying to use the other and doublecross them in the end. The backup for the operating system, that would allow an Alex-controlled Megadeus to take over, supposedly was placed within R. Dorothy’s OS by old Wayneright.
This struggle is having the effect of destroying the environment in which the common inhabitants of Paradigm live, both physically and notionally. In the end, as it all crashes the real final arbiter is revealed as an uber-Megadeus intelligence known as Big Venus. Whose real creator, author of the system that Gordon Rosewater used to recreate the world, is his daughter… Angel. Whose completely suppressed memories were held in reserve in case it is was ever necessary to bring Big V about to do a hard reset.
When it all is coming down, and Big-V seems ready to do a total reformat, Roger performs his final feat of negotiation – as the hard reset would mean erasing all the “reconstructed lives” and those instances of unpredictability that brought about the crash, he pleads the case that the life-consciousness, the life-experiences of those inside the sim, ARE worthy, that they should not just be wiped away, that a sim life is better than nonexistence.
The “lives” of Paradigm are spared, their world is reconstructed, and we get the briefest hint, that in the middle of it all, Dorothy, Angel and Roger, now awake and aware, have come to terms.
HOWEVER, VERY LITTLE OF THIS IS EVER EXPLICITLY STATED SO, YOU HAVE TO INTERPRET, so anyone else’s read is as good as mine.[/spoiler]
