Current Jax Theory:
He (accidentally) hit someone with his car, which is what the flashbacks to the real world were showing. The “someone” was likely a young girl, probably 10-ish.
Evidence:
Everyone in the circus is relatively “tortured” by their digital form, e.g. Zooble hating how they don’t have a singular form, Gangle’s mask controlling her emotions. This could extend to their rooms and the wide shot of Jax’s room showed a lot of feminine stuff, but generally stuff a little girl would have in her own room. Jax’s digital form is a plush rabbit, maybe the girl was holding it when he hit her? Basically, he’s constantly being reminded of the worst mistake of his life…
This would be why he doesn’t want to go back to the real world and why he’d have no one waiting for him. The End!
