I looked everywhere for a similar topic and found none. So I'm making this.
It always occurred to me that Simba seemed more excited during the Elephant Graveyard scene than Nala did. I guess in my own head I've always pictured Nala as the older, more mature lioness cub who gets dragged into messy situations by the mischievous Simba.
During the bath scene and all of IJCWTBK, Simba and Nala seemed equally thrilled to ditch Zazu and go explore the Elephant Graveyard. Yet once they find themselves there, their reactions are completely different:
Simba is the first to step forward and his face goes from D= to =D while Nala retains her shocked expression.
Again during this panning shot, Simba is smiling, Nala is not.
See that? She is frowning, as though doubtful. Simba, on the other hand is thrilled.
Enough screengrabs, lets look at the dialogue.
Nala: It's really creepy.
Simba: Yeah... Isn't it great?
And then Nala chuckles, and reminds Simba that they could get in "big trouble," but Simba's response is LOLYUP. Nala seems to be the one who better understands the gravity of the situation, another reason supporting my theory that she is the more mature of the two. And, in my opinion, it does sound like a feeble attempt to get them to turn back.
Next, Nala sees an elephant skull and laughs "I wonder if it's brains are still in there." But Simba is the one who walks forward and suggests checking it out. Simba ridicules Zazu for being scared. And Simba walks boldly forward and declares that he laughs in the face of danger. We don't get to see Nala's reaction to any of this.
Finally, notice this exchange by Simba and Nala in the sequel:
Nala: Simba. Who does she remind you of? Hmm?
Simba: Huh? What? Who?
Nala: She's just like you were when you were young.
Simba: Exactly. Do you realize the dangers we put ourselves in?
[She tackles Simba and puts him on his back.]
Nala: You mean the dangers YOU put us in.
So anyway, what do you think? Am I misunderstanding that bit in the Elephant Graveyard scene, or is Nala really just hiding her nervousness and going along with Simba's antics?
