As an example, if anybody has seen 'Avatar: Last Airbender' Aang, the next Avatar and the strongest being in the Avatar world, is able to spiritually connect with the past life Avatars. What if the same goes for Kion? It was stated in 'Return of the Roar' that Kion posses the power 'roar of the elders' in which the kings of the past roar alongside him when he uses it, in that case, maybe Kion has a stronger connection to the spiritual life than Simba, Nala, Kiara, and even Rafiki, that's why Mufasa can show up at anytime but only to Kion.
Hows that sound? What do you think?
