The more screen time would most likely be given to the new characters we've seen in episodes 15 and 16, since it seems fairly obvious that they could be potentially important.

That, or Sun and/or Penny are going to be like Haru or the Freedom Fighters from A:TLA; they show up once, then are never seen again until the finale.
