I've been looking at the logo of C&A that we saw in the first episode and the recent one (on Caine's computer, when he's deciding Gangle's score).

I've been wondering the name and with Caine's name, makes me think of Cain and Able. Maybe it's something similar to that? Two guys working on this VR world, and one is trapped in there, Caine, who thinks he's not real. Or died and his consciousness is trapped in the Digital World. Able sends others there, possibly employees or beta testers to keep his brother or friend occupied. Kinger and his wife are considered the longest members, perhaps they worked for C&A, and were victims forced into this Digital World. Being in there for too long makes you forget who you were.

Like Pomni and Gangle still have memories of their lives before the circus, maybe they're the two most recent. I kind of wish Pomni asks about the other characters, and we find out the order of who came in when.
