What if Mufasa had arrived one minute later at Scar's cave Scar would have already consumed Zazu, and Mufasa would be very angry with him.
What if Mufasa had survived the fall? If Mufasa survived the fall, his spine would still be severely broken, and may never be able to walk again. Because of this, he would have to abdicate from the throne because he can't protect the pride with a broken back so Simba would have be the new king, but Sarabi would probably have to reign alongside him until Simba's ready to reign by himself. For Simba, he would be happy that his father is still alive, and have to take over for his father. For Scar, since Mufasa is severely weakened already, he would not have to worry about killing Mufasa, and would try for a third time to kill Simba.
What if Scar had escaped the angry hyenas? If Scar had the finest luck to escape the hyenas, he would either get burned up in the flames or run away into exile from the Pride Lands. However, he would probably come back to Pride Rock with Zira and the Outsiders as his allies to regain his throne from Simba.
What if there was no such thing as Mufasa's ghost? If Mufasa couldn't come back as a ghost, then, there would be no hope in convincing Simba to return.
What if adult Simba had not recognized adult Nala? If Simba didn't recognize Nala at first, he would ask her what her name is, and when she says "Nala", he would be very excited. Or Simba and Nala would continue their fight until one of them gives up.
