OOC:
Just to clarify, by sheer dint of them passing their Vigilance checks, they see through the illusion—that has nothing to do with the threats rolled, only the successes/failures. So if the goal is to prevent more folks from seeing a tiger rather than a bird, y'all will need to spend some Story Points to upgrade checks, or else use threats to cascade enough blacks down the line to hopefully cause some of the successful rolls to fail.
Fright checks are incoming, as well, so some of the threats can be used to impose setbacks on those if you wish.
But assuming we leave the rolls as is, I think causing a religious schism along the passed/didn't pass axis can work to your benefit by sowing general chaos and preventing them from presenting a unified front, at the very least.
At the rate of 2 threat per black die, you could throw another black die on the Night Creeper Rival 2. Coupled with swapping out that first purple for a red, that may be enough to make them fail their check. Then use their 4 threat to throw 2 more back dice at Jacey, and you potentially reduce the number of passes from 3 to 1. That gives you a situation where the guards are like, "It's a tiger!" while everyone else (including the leaders) is saying, "No, it's Harridan!"
You can get that effect with three of the rolls passing, as well, of course. It's just easier for 3 groups to oppose 4 than it is for 1 to oppose 6 in a religious schism.
