That is a good guess and I hope it is the case for the sake of the fandom! But it just seems so puzzling to me that Jasiri would make a return in this episode when we're getting introduced to a bunch of new characters too. Also, why wouldn't the plot synopsis hint to this, even just by mentioning another pride of lions? Why is Jasiri chosen as the main focus?

Again, not that I don't like that but surely the creators know that the Outlander cubs are a way bigger deal to the majority of the fandom.
I think someone mentioned before that this could be some kind of prologue to the Outlander cub episode. That's actually starting to make sense too.
I'd cry with laughter if this episode suddenly introduced a bunch of new Outlander lions that have
nothing to do with the TLK 2 cast, which is why they're not hinting at them. Like, just a totally new Pride. Must be the most frustrating thing in the world if you genuinely like the Outlanders...
