Hi!
No problem, our discussion lives from the various standpoints we have.

My look at it is not simply fanfiction, I ´ll show you why I think so below. As an aside, with the game advancing further and further it becomes clearer that Sophia/Abel are shaped to be a middle path to go on. They certainly are not something akin to Kath and Chuck, opposing them, but also have few qualms to do what they consider necessary. Sophia (we know not much about Abel so far) is one of the few bright lights in the club, but she has a couple of black schlieren on her.
We should not forget that so far the game never shied away from showing consequences of events happening, e.g. Jacob putting Oliver into coma. Until now there has been no pics showing what happens in the cellar, while we have info on some other "delicate" happenings. There is someone kept prisoner in there, that´s for sure, but I doubt that Sophia does much to him/her. The advances of her "Viagra+" are far too quick even for a genius like her (remember Abel and Sophia are in the club not much longer than our hero is) to be made in that cellar with one "lab person".
It is far more likely that the newer versions are coming from Abel and Sophia´s black labs, with additional research info gained from the use in the club with older versions. It is complete BS to believe they research the drug at the club when they have black labs available. Abel and Sophia are shown as two geniuses, she even outshining him. There is no way in hell that they would be so dumb as to research an illegal medicine/drug in a location not really secret and under control from others. This could potentially ruin Abel and his firm´s sterling reputation, so a no go. The "research of super-viagra" in that cellar is most likely a scam, a stage play to seem similar deviant as many of the other VIP members.
You might remember our discussion on personality imprints, grafts and special training, worthy of secret services and stuff. I theorise Sophia (and Abel to a lesser degree) has several done on her to be able to function undercover in the den of depravity the club is. I think they underestimated what these imprints can and cannot do and what they will do to them over the long run.
What in this discussion on Abel/Sophia is also frequently lost, whatever the exact parameters of their relationship are, Sophia is his chosen successor. Given Abel´s age, he will retire within the next few years and Sophia will become leader of a medical empire. His corporation is depicted in the game as one of the truly major players in medical production and research.
