i think the saddest, most traumatising part about the stampede is mufasa’s reaction to scar saying ‘long live the king’ 

not only does he realise that he’s about to be murdered—knowing mufasa that’s probably the least of his concern—but he’s just realised it’s all a trap. the fate of the kingdom now relies on a tyrant. his brother finally got what he always wanted. and worst of all? his son is still alive. he knows simba’s still alive because he got him onto the perch before he tried to get himself to safety.

mufasa knew scar was going after simba next, and he couldn’t save him.
