Ukumbusho means Reminder in Swahili. As what has been said above, it will likely involve everyone remembering the kings of the past, including Mufasa.

But there's a Halloween twist to it. Remember another king of the past, who is currently plotting vengeance in a volano? Maybe Scar somehow enters Kion's mind and makes up the story of Mufasa.
