But Jaune isn't their "Simple soul"... he has no relevance with the final plot/challenge they want their "simple soul" to overcome, this is why Ruby doesn't appear to be developed... the writers are waiting for a specific moment to reveal what they have(or possibly develop her at all) and that is the problem.
