I know a lot of the "exiled" creatures have little incentive to support the status quo, but Scar's comments a few episodes back about wanting to recruit the jackals got me thinking. Shouldn't some of the show's established villains refuse Scar's offer? Scar wasn't exactly a great leader for the pride lands, and even the hyena's were having trouble finding food at the end of his reign. I get that Janja is short-sighted and gullible, but would Reirei actually want to join him? Scar doesn't seem to mesh well with "jackal style", and despite being a villain, she mainly is looking after her family and trying to feed her kids. I think it would be pretty cool if the jackals actually refused to work with him, or were maybe coerced into it instead.
I could also see the vultures refusing, as the circle of life actually benefits them. I know they want more, but I'm pretty sure they still have a steady supply of carrion even if they don't always get what they want.
