I think that neither scar nor mufasa could be her father because some stuff in the movie itself wouldn''t make any sense. Before getting into any of that,i would like to point out that what was said on the lion king reunion (about her father being scar or mufasa) was actually a joke,considering they said taht roger allers could be her father.So what they were trying to say was that her father is unknown,at least for now...If there won't be another sequel.
But back to the subject,Scar can't be her father because on the ion king on broadway he tried to mate with her...
Mufasa can't be her father becuase:
-in the movie he had no interaction at all to nala or sarafina
-in the scene where they sleep,mufasa sarabi and simba are on the middle rock,as they represent the king queen ad prince,if nala was his daughter,wouldn't she be up there too
-simba says that nala is his friend,but if mufasa was her father he would have to say sister,right?
-Zazu tells how it's a tradition going back ages that they will get married( just like in the royal families),and that means that it would be impossible for them to be step siblings because that would mean that pride rock lions were incetious for generations.Nw how little sense would that make!
-When mufasa saves them from the hyenas,he says:'If you ever come near my SON again...' if nala was his daughter,he would probably mention them as his children
-Later on when mufasa is talking to simba alone,he says that he is dissapointed in him because he didn't listen to him and further more becuase he put nala in danger-which is normal for him to worry becuase for a parent taking care of someone else's kid is a greater responsibility than to take care of your own.
And to wrap it all up,it's a disney movie,so figure it out.
sorry for typing so much,but i had to get that out of myself...
