I absolutely LOVE the way their characters contrast each other in Digital Circus.

For the first 1/3 of the show, Ragatha is seemingly established as the kindest member of the circus by far. Meanwhile, Jax is blatantly the Token Evil Teammate of the circus crew, being almost sociopathic at times (episode 2). The differences between the two is best empathized by the fact in episode 2, Jax is the only member of the circus Pomni does NOT imagine saving her while Ragatha's hand in the central one doing so in her final vision. Episode 3 further proceeds to establish Ragatha as the caring one while Jax seemingly wants nothing more than for people to suffer.

However, in episode 4, we begin to see a slight shift. During their adventure at Spudsy's, Ragatha becomes way more insensitive and begins saying things she normally wouldn't say. Complaining about Pomni hanging out with Gummigoo (her NPC friend who got exploded in FRONT of her) over them, calling Zooble a grouch, Gangle "annoying with her happy mask" (Ragatha calling someone's fake positivity annoying is peak irony/hypocrisy) and telling Jax right to his face that she hates him but doesn't want him to hate her. Gangle finally drops it on Pomni "I love her but after a while it gets hard to tell how genuine she's actually being"

But with Jax, its the opposite. As soon as he realizes he'll actually face consequences for his actions, he tones it back. Especially after his employee training video. Not only does he NOT do things you'd normally expect (like step on Ragatha when she doesn't move), he even strikes up a GENUINE conversation with Pomni that leaves even her surprised at it.

Episode 5 shows the differences on full display and why Pomni bonds with Jax. Jax is willing to let his mask drop and show his true vulnerabilities, to some extent. He's a jerk on the outside but actually has positive feelings within. Its clear despite everything he DOES care for the other circus members and a large portion of his jerk behavior is just trolling. Meanwhile, Ragatha is so constantly positive, its way more difficult to tell when she's being genuine. She has negative feelings hidden within. While Ragatha does care, its not as much as pure as one would initially think while Jax pretends to not care but does.

And the fact both of their personalities are coping mechanism's also highlights it. Ragatha had an emotionally abusive mother and thus, she's a people pleaser who wants validation. Jax lost a friend to abstraction and is trying to avoid bonding with anyone else out of fear of being hurt.
