If you don't mind, I'd like to say a little bit about what the new game might be about:
1. First of all, I think it's no secret that the game takes place in Romania on the Carpathian Mountains. Nowhere has this information been officially confirmed, but I am familiar with the visual representation of the area, because I myself saw these mountains when I visited my grandmother in a Ukrainian village. I'm sure you know the Carpathian mountains thanks to the famous Transylvania, where, according to the novel by Bram Stoker, count Dracula's castle stood. Also in the trailer on the gate in front of the castle, you can see images of execution, reminiscent of impaling, which were so common in the times of Vlad Basarab and Ivan the Terrible.
2. Of course, I was impressed by the architecture of the castle. I immediately wondered who owned this building. And I think the trailer hints at that.
This owner could be Oswell Spencer. I'm sure you've noticed the Umbrella symbol, but the clue is that this symbol, if you remember Resident Evil 2002 well, sprouts from the Spencer family cross.
The second clue is the coat of arms, which can be seen at the moment when lady Bathory (let's call her that) is talking to someone on the phone. The coat of arms is very similar to the mix of the Spencer coat of arms from Resident Evil 2002 and the Spencer coat of arms from Resident Evil 3.5.
The third clue is the bas-reliefs of lions with rings that adorn the entrance doors to the castle hall. As you may remember from Resident Evil 2002, such a bas-relief decorated the door that leads to Spencer's room.
3. If you look closely at the embryo, you will notice that it is parasitized by a foreign organism. This organism has several characteristics of the Las Plagas parasite, which is why I assume that Spencer's castle in Romania is the location of the parasites that Umbrella used for NE-α. Perhaps the castle was built very long ago and especially close to the source of these ancient organisms.
As you know, the reason why Umbrella had to artificially recreate the parasite instead of just using it was because the only viable parasites were only in Spain, since they were mummified by Ramon's ancestors, so I expect the Spencers only found fossils.
Also note that the embryo closely resembles the technique that Evelyn was created using. If a mold gene was inserted into Evelyn when she was an embryo, that child was a victim of the parasite. Perhaps The Connections tried to use parasites to implement their project even before the discovery of the fungus and its cultivation with the help of a virus.
Perhaps, after Spencer's death, the castle was privatized, and the syndicate set up another research center there.
4. Note that one of the women in black who attacks the protagonist can release insects, thus reminding Margaret. So I assume that these three women are agents of the new girl, which is lady Bathory. If Evelyn ordered altars to be made for her older sisters, Bathory may also be prone to folk horror, so she founded a cult and recruits villagers using mental control (we've already seen in the trailer that someone tried to take control of one woman). Perhaps Bathory considers herself the new heir of the Spencer family, so the wings and nest resemble the cross of their family.
And she drinks blood because she believes that this way she can stabilize aging and preserve eternal youth.
5. Chris Redfield has always had a consistent personality. Even though he's a good guy, he's never been a perfect superhero. He could quarrel with his superiors and take the initiative into his own hands, even if this initiative is revenge. Therefore, if Chris suspects a corrupt connection between American politicians, Umbrella, and even the BSAA, Chris will not be idle. It is easy for me to believe that he can act as an illegal avenger in this story.
But!
If Chris and the masked men steal the baby, I suspect that Chris may be blackmailed, because I can't imagine any other reason for this act.
But why kill Mia? It's hard for me to justify this murder. I can only cite two reasons that underlie Chris's motivation.
Obviously, Mia is still a criminal who should be held responsible for the incident in Louisiana, but for some reason it didn't happen. Either Mia hid her involvement and Ethan backed her up, or Umbrella did. In the first case, something terrible could have happened that could have been prevented if Mia had not kept silent, so Chris carried out an act of revenge. In the second case, Umbrella may have a connection to the syndicate, and Chris was sent to clean up the mess and apprehend or destroy the traitor Lucas. In that case, if Mia is still working for the syndicate, she's still a useful ally. Then Chris simply punished her.
But both of these options are not excuses for me. If Chris did this consciously, he will have to be held accountable.
Thank you for your time! And sorry for my poor English.
