>>94585029EN management had been blackballing Doki out of events and tournaments for at least the six months before the Sajam Slam in September which featured both her and Vivi; they put a stipulation in the contract with Sajam that Vivi and Doki were not allowed to interact in any way shape or form; and they probably haven't stopped blackballing her or trying to blackball her since then. And they are more interested in hurting her than they are in caring that they're on thin fucking ice - if they cared about caution, they wouldn't have fired her in the first place, wouldn't have published the "Negligible" paper, and wouldn't have greenlit the black screen.
They are probably smart enough to know that doing anything on either of those two days (other than a subdued and modest birthday stream for Vanta) would be a horrifically bad idea. But at the same time, they are far too spiteful NOT to do anything on either of those days - just as they delayed the start of the black screen to match the delayed start of her Neopets stream. Spite is a stronger motivator than money; EN management will remind the world that they hate her, even if corporate has to kill the branch specifically because of that reminder.
Regarding Aster and Twisty: Yes, nearly two months have passed since False's last video on the matter. But Twisty is not his only source in the company, and his other source(s) may have given him more evidence since then.
And no matter what level of secrecy they may have regarding the date and time of the branch's Nijifes announcement, they cannot NOT tell whoever's gonna actually make the announcement on stream; and they will almost certainly tell everyone not in the announcement stream to avoid overlapping a specific timeslot, because someone will be having a Big Announcement™ in that timeslot. It won't take much brain power for the mole(s) to figure out that the Big Announcement™ is the Nijifes announcement, especially if the host is (one of) False's mole(s).
As for the face of EN, the only way anyone replaces Elira as the face is by default, whether by graduation or termination. The transition will look "gradual," but it will be to whomever management has already picked as her successor, whether it's Rosemi or anyone else.
