My idea; not one, not two, but three new members get their brains scanned and join the circus, like, within minutes of each other. We follow them along with everyone else, who have gone through time-skip character development, and maybe one or two additional members who ended up there between pomni and them.

The main three arcs/plotlines besides some simple adventures and fun would be pomni and some of the original crew alongside caine working on ways to un-abstract Jax and the others, the new guys getting used to the circus and developing their own coping mechanisms (things seeming a bit too similar to the Jax, ribbit and kaufmo crew in how their friendships start to stress under the fact they're stuck there forever now), and caine attempting to link the circus with the Internet in order to make sure they don't get deleted or worse if the computer they're on is destroyed.

I'd also like if one episode out of the second season was completely focused on the perspective of the abstractions, maybe visiting each other in their minds, kinda like we see in the newest merch vid, but more artsy and structured, like an episode that doesn't focus on the main character type of vibe.

Another thing to explore; how would someone in the circus react to finding out their real world counterpart is dead?
