So this episode is clearly setting up that Pomni and Jax can become good friends given time, as demonstrated by him getting along with Evil Pomni as well as numerous other things in the episode, like her not voting for maid Jax and laughing at his bits. Clearly this is making Ragatha jealous, since despite being the most outwardly positive of the group and doing the most to try and support Pomni, she's forming more meaningful relationships with the others like Jax. I guess Ragatha is the most isolated due to her lack of authenticity.
