Theory

After episode 3, I came up with this theory, and episode 4 only gave fuel to my thoughts...

What if the Circus is a self-help system, and you only get released once you fix whatever internal struggle you're dealing with?

Thanks to Ep3, we know that Zooble has dysphoria, and Caine says that they have an entire box of exchangable parts, therefore Zooble wouldn't be released until they're completely comfortable with the body/bodies they've been given.

With Ep4, Gangle mentions that her comedy mask is usually broken very soon, leading the possibility that the Circus is trying to get Gangle to be happy even without masking her depressive emotions.

What do you all think?
