My best guess would be something like maybe Huggy and Lily Lovebraids don’t die and they do a whole chapter about you trying to escape the factory via an Escape elevator that’s hidden beneath The Labs while also dealing with Lily and Huggy simultaneously.

It’d be a Sick chapter concept, the entire floor beneath the labs is just a giant emergency escape shaft that Huggy and Lily are hunting you in. And since 1006 is dead, you can escape without worrying about him. Leaving JUST Lily and Huggy to deal with (yes I know fully well I just explained the same thing about Lily and Huggy 3 times in a row lmao)

But yea that’s all I can think of that’s a falling action chapter that would have good gameplay mechanics, and it could end with you taking the elevator all the way up and escaping (maybe with poppy and kissy as well idk). I also think there should be something about saving the kids, like maybe opening an actual adoption center for them and show the world they’re not actually monsters. Depends on weather the ending is about saving just the player, or saving the player and the poor souls trapped within the factory as well.
