Honestly I think Nala takes more control of the Kingdom than Simba does. I mean, she doesn’t let him know that since she’s aware of Simba’s dire need to follow the in the footsteps of his father, but Simba is a very damaged and hotheaded lion that she balances out with her calmness and clearer thinking. So, Nala insists on following Simba everywhere and helping take care of Royal Duties so she can keep him grounded if things start getting out of hand with his emotions.
I did not write this. I though I would upload it since I totally agree. Found this on Tumblr
