I think you're confusing what the term Character Development means. Penny and Sun have no character development because they don't change in the two episodes we see them. Sun is still a law breaking Faunus with good intentions and Penny is still a strange girl that we know nothing about. The only two that had any character development in those episodes were Blake and maybe a little bit of Weiss. Blake (hopefully) learned to trust her teammates and not let her present be dictated by her past and Weiss learned that the past is in the past and not all people (or Faunus) are the same.
