By the way, speaking of mold and virus, my personal theory is that the origin of the Black God is very similar to the origin of the Queen Leech.
In other words, at some point it was a life form that evolved because of the Progenitor Virus and therefore learned to steal genes. Thus, it has assimilated biomaterials for centuries and has become something completely new.
In fact, we can easily doubt that the abnormal mold is a fungus, because fungi do not have real tissues, since their cells divide in one direction, after which these filamentous hyphae branch and intertwine with each other to form bodies such as mycelium and fruit body. But the mold from the games not only has tissues, but also has the genes of different life forms in them. In other words, it is a hybrid life form, which is attributed to fungi only because it is structurally closer to these microorganisms.
I think this is equivalent to how we can hardly call the Queen Leech a leech, because it is a new life form in its essence.
And Oswell Spencer, being passionate about eugenics, decided to find the key to evolution itself, which could lead humanity to the next stage of their biological species, avoiding thousands of years of natural development. I think that the meeting with Miranda became for him a proof of the concept that very powerful biological agents that can give immortality and turn people into weapons actually exist in the real world. And it could also support the theory that viruses, including the Progenitor Virus, so named for a reason, are directly related to the evolution of all life forms on the planet.
And again, Spencer believed both Marcus' theory of virally-driven evolution and Travis' work, although the scientific world did not accept any of this. It's kind of hard for me to believe that it was just silly luck, but we know that Oswell was fond of archaeology and even had a book about El Dorado, so he could have witnessed something special. That's why I think everything fits perfectly.
Similarly, I just love how the Spencer family crest was added to one of the photos. This was a big surprise for me, because even such a devoted and optimistic fan as me doubted that the developers would remember it. And I was wrong.
However, there is a certain irony in the whole story of Oswell E. Spencer. It seems to me that the new game intentionally established parallels between Miranda and the Queen Leech, since their abilities are described in the same way on katakana, and they are also both associated with the image of Jesus Christ. And the irony is that one M-mimicry gave Oswell direction, which led to the beginning of everything, when another M-mimicry ruined things, which led to the collapse of everything.
