If you think about it, the Outsiders were established AFTER Scar's death. They are the group of lions/lionesses that still followed Scar. So that kicks Scar out. And the hyenas aren't really Outsiders, they aren't lions, therefore they aren't apart of the prides. The Outsiders title follows around the lions/lionesses that were in TLK II, not TLK. See my point? ^^
