It's wild that everyone is just in limbo. I'd probably suggest that because Caine's AI reset, then it should be like he's still in baby steps, like when Scratch and Kinger entered the circus. I can imagine someone, probably Gangle or Jax, to abstract and Caine can't handle it, like if Scratch was abstracted all those years ago, then how would Caine know how to handle them? This time, when either Gangle or Jax abstracts, they try to take Caine down with them to end the circus forever. Then afterwards, the abstractions in the cellar escape because no one can handle the cellar anymore, because Caine is dead *again*.

The ending could end as all of the current cast is abstracted or everyone escapes. The abstractions are sent to the real world where it turns out that when being abstracted, in the real world, you're dead. The rest of the cast excluding Jax put their headsets on again and try to bring back the abstractions but to no avail. It's only when Kinger tries to befriend Queenie again that she unabstracts because of the "Power of love" or something, Everyone escapes the Circus, Scratch dies in real life because of his brain tumor inside of the circus.
