[TMA finale spoilers] Because i enjoy being miserable, imagine if melanie, georgie, and basira were still fucked over after the world returns due to their ties to the archives. The entire world fell victim to magnus’ plans. Even if it took a while to make the connection that the Institute was the source, I’d be surprised if it wasn’t eventually tied together by the governments of, again, the entire world, in a desire to figure out what happened and why and to avoid it happening again.
I can easily imagine ex-avatars ratting each other out and giving out whatever information keeps their heads on their shoulders, including calling out the Institute. And then it’s just a matter of finding who was employed and which of those people were involved… Obviously an incredibly unlikely scenario if everything is reduced to rubble (including any paper trails), but like…those three could absolutely be left in a world wanting someone to pay, and them being the closest living thing to that desire, and even if they’re safe due to destroyed evidence, they could be living out the rest of the unapocalypse in anxiety
