I think what we're going to get is a back and forth of episodes focused mainly on just one or two sub-plots, so there will be more DC focused episodes to come, and more roadtrip centric episodes. Indeed, I don't think we saw anything of Hero this week at all, so presumably that'll be coming up in the rotation too.
Honestly I prefer this approach to serialised storytelling than the drip-feed approach, where each and every plot thread and character get's exactly one beat of advancement each per episode, and no more, making each individual episode a bland forgettable smear in the larger seasons long story.
Thankfully this is seeming less and less common and shows rediscover the concept of episodic storytelling that also fits the highly serialised format, but for a while there it was pretty standard in the early days of the binge craze.
