[quote="Panpardus"]It's the synopsis given by the Lion Guard FB fan page, so I'm pretty sure it's legit.[/quote]
That synopsis sounds plausible. They could just have Ono say something like Zebra stripes ward off Tsetse flies by confusing them. It's common knowledge realy. I just don't know how Thurston alone could ward off a swarm of tsetse flies. I doubt Kion will use The Roar on the tsetse flies as it would kill them. I also doubt that the bugs in the Lion King universe could suddenly be intentionally evil.
[quote="zerodix"]Three days to go.. no preview yet. I'm checking on the lionguard wiki, nothing there as well.[/quote]
I doubt that there will be any other previews than the one we have already seen. Maybe they want Jasiri's appearance to be a surprise.
