(I am new to tumbler so idk how all this works but here I go)
So in episode 9 we see that the circus members are not actually people but brain scans and caine can access their files or brain scans thats how he looked up the members irl version. So there must be a backup digital brain scan and as the characters go through stuff their memories of the circus keeps getting updates (imagin every adventures as levels even if they are not) so they remember all their adventures as they talk about it often. So my question is all the abstracted characters can't caine use the back up and bring the abstracted people back? He can delete the part where the character broke completely (ofc it happened over time but sure the other members can help) and got abstracted and use the data to re-spawn the abstracted ones.
