This episode was kind of mostly about Taiyo and training him to get better at owning and controlling his powers, so I think this sort of episode is warranted given the point of the story we're in. We also got a little bit of insight into Tanpopo (nothing that overly relevant, but that opening scene was surprisingly cute), as well as HInagiku and how they came to be - I didn't expect any of that, by the way, but it makes a lot of sense. Compared to the past two episodes, very chill.
