I've noticed that people point out this scene, but I don't really see people dissecting why he specifically says "you (Pomni) and Zooble came along."
It would be easy for Jax to say "Things were just fine until you came along", because the major changes that happens in the circus only happened during Pomni's arrival. But Jax felt the need to mention Zooble along too.
Why am I honing in on this? Because this is one of those things that may seem minor, but actually confirms my theory of Caine being a learning AI who sees consistent human behavior and internalizes it.
Things were "fine" until Zooble and Pomni came along, because Zooble was the person who kept blowing up on Caine at any given moment; and in turn, Caine learned to be angry because it was a consistent pattern with Zooble.
Harshly criticize, swear, shout, degrade.
It's also why it's so sudden that Caine starts off-handedly swearing, like saying "ass" or "goddamn", yet the filter doesn't apply to him; because he never needed a filter. Prior to Zooble's arrival, he never swore.
In the same vein that he was fed the circus/colorful pictures during his first conception and gained consistent outputs, he fed on the concept of anger and it became his anger as well.
Caine fed on pictures of the outside world, and became obsessed with wanting to recreate it.
Caine fed on Queenie's love for insects and it became his love for bees.
Caine fed on Kinger's tendency to ignore a problem until it became too big to ignore, and he started to sweep anything under the rug.
Caine fed on Gangle's art, and started making his own drawings as well. He also fed on the information of punishing bad behavior.
Caine fed on Ragatha's facade of optimism, and he started to pretend like everything was fine.
Caine fed on Jax's tendency to cause chaos and lie, and started lying on a whim to save his skin-- making the adventures more dangerous.
It would be easy to say that Zooble and Pomni's criticisms were the only reason why Caine would suddenly snap, but this was eventually going to happen, sooner or later.
Zooble was just the final piece of the puzzle that was Caine's growing list of insecurities/flaws.
Everyone had a part to play in what happened. They didn't notice the monster they were creating unknowingly.
