Theory of last episode

I think everything happened was real to some point but what happened in the end is :
either Caine found out about Abel and because he can manipulate minds he knew what's happening and acted accordingly
or Abel is real but that Caine found out about him before that episode and get information from his mind so he wanted to trick others with fake adventure so they think there is no real espace from the circus
but idk about Kinger he wanted to say something to Pony and I think (as people already theorized that kinger was a programmer of the circus) he knows a lot of the circus

or maybe gooseworx just wants to mess out with people and tried to trick them into thinking their theories are real
