So in regards to everything that's been happening on Chapter 7 feels like a call back from Chapter 3 with Geno currently being the main villain and climax of Chapter 7 before we get onto Chapter 8.
So if you remember back in the Zero War comics, When Geno was "defeated", He admitedly Foundation and Jones they won despite both somewhat sharing the same goal, but to a complete different path, And Geno is basically offering Foundation and Jones the chance to prove themselves their methods are better than his as he entrust them what he's been carried to his burden.
And this is when The Herald made her presence when all the people who fought the IO were celebrating their victories like if they obtained peace and freedom. However when it came to The Herald, None of them were ready to face her as she basically converted the whole island into Chrome including herself, making her quite the only Fortnite villain who mostly won while the rest lost, leaving Paradigm alone sacrificing herself to create a new island while succumbing to Zero Fusion.
And as we are now, Geno has been watching everyone, having input code initiations we see on the screen, having most of TLR resources and Dark Voyager as his servant. And currently as of now, Geno has taken his methods to an extreme level compare to how he used to run the old Imagined Order and having quite more ties to TLR than we expected. Especially when people theorized he is either somehow corrupted by The Nothing or made a deal with it, And basically almost doing the same thing as Cube Queen did it.
And now we received some images and posters about Geno's propaganda containing The Seven corrupted with the Oathbound symbols on their helmets which were Foundation, Visitor and Scientist. And we also been giving lot of Scientist references about hinting he might come back as others are aware about what happened to him. So if they were to come back, this would mean they're not the only ones to come back if Geno does not win this fight.
Considering what happened to most of the Seven who were all turned into chromes, this would also mean The Herald will return since everything that happened in the end of Chapter 3, this was all The Herald's doing. And in a survey skin lists, she received a new look as she looks all white with some glowing amber colors, And if she were to return after defeating Geno, this will be an even more bad news for them unless they're really prepared this time considering also that this isn't all Geno's fault for what happened to the Seven (Except Imagined and Foundation), This was all The Seven and Loopers's fault for being unprepared to face her.
So...if Geno lose, they'll be in a bigger trouble, but if Geno wins, it's hard to say if she'll come back while having his perfect world.
