Carrying on from their brief conversation in the previous episode, there are multiple instances where Pomni and Jax genuinely get along with each other, with Jax being more open and vulnerable than he usually is around her and Pomni making a genuine attempt to understand him in "Untitled".
During the bartending segment of the adventure, while Jax pokes fun at Zooble, he legitimately asks Pomni about what she did prior to ending up in the Digital Circus. Beyond some friendly snark, he doesn't mock her for being an accountant or for the urban exploration (and recording of said exploration) that she did on her off-time.
Also during softball, the group voted to put Jax in a maid uniform, much to his displeasure. However, Pomni is notably the only one besides Jax to vote against doing it. Throughout the softball game, Jax and Pomni can be seen casually talking, and at the end Pomni even smiles and laughs at his antics. As much of a jerk as Jax can be, it's still nice to know that he may now have a friend that can see him as more than just that.
When Jax's original self reemerges and starts devouring the Evil Jax, Ragatha and Pomni are left bewildered. But Pomni's reaction changes to laughter at Jax's behavior, which catches Ragatha's attention, leading to an awkward moment as Pomni averts her gaze while Ragatha stares at the jester in disbelief.
At the end of episode, Jax, rather casually, offers to show Pomni something in the hallway that he suggested earlier, which she actually takes him up on.
