OMG that was so funny! Sweet and touching and... oh, skip all that, I loved it!

they should have had that in the movie!
ok so this what I think the whole thing is and such:
so Simba talks to his father and when he is done he doesn't run home right away. instead he runs back to the forest to tell nala he's going back, but when he see's her, he changed his mind and starts to leave without telling her. She wakes up, they talk. When he says "I love you" That was refering to them in "Can you feel the love tonight?" He probably told her he loved her at some point and they didn't put it in the movie. And when Nala says "I thought you wanted to stay" She was recalling the argument that had happened earlier, and it wasn't actually saying that SHE wanted to stay. I think she was staying the night then going back in the morning with or without Simba. Like when she says "...And that's what I wanted..." I think she was gonna go back with or without and come get simba if they won over scar or something. Simba doesn't want to lose her and runs home while timon and nala argue, Nala goes after him like she was gonna do in the first place, and timon and pumba follow.
The pumba music was really off, but it was kinda funny.

That's how I see it. ^_^
