I came up with a nonsense schizo theory.
What if Pomni is so trusting of Jax because Caine recycles elements of abstracted players to make new ones? That would effectively make Pomni a partial reincarnation of Ribbit. That is why she did the frog pose and Goose said that she was originally a frog pre-production. It was actually a 4D chess move to distract from the fact that she still is.
