Yes, also the bad episodes get the change to be discussed. This is one of the worst episodes of the series. I mean, Bluesky & Raincloud could also had make some appearances in the third season. Two grifters, working for Watership Down (at least, in the end of the episode, I could think this is possible).
But so, it looks like the creators had to fill the season with 13 episodes. So we could say, this is really given away potential.
