Different options for what I think could happen. In the TADC finale:
1.They deal with the repercussions of killing Caine as the circus collapses around them and they have to somehow reboot him to stop the circus and everything in it from going corrupt
2. The circus stabelises but isn't the same as it used to be, they still can't escape but now they have to learn to live in the world on their own, perhaps making peace with it as they tried to at the start of episode 8.
3. The circus is actively falling apart around them as they have to race against the clock to try and escape before it's too late
4. Bubble as the second AI comes in to stabilise and rebuild the circus, potentially either becoming a new version of Caine and leaning into the same torturous tendencies or working to try and help them escape.
5. With Caine gone the boundaries of the circus are much more loose, the abstracted get out and the gang have to try and either fix or contain them
6. With Caine gone they finally manage to escape the circus and can finally return to the human world but second guess themselves and go back to see if they can save the abstracted
