I was so unsure/frustrated about Twilight becoming a princess just as much as most people. I just couldn't see this new plot point working for season 4 and on. And for the longest time I kept thinking to myself...
"Why am I so frustrated?!"
Well, I've come to the conclusion that I was mostly frustrated NOT with the fact of her being given the responsibilities as a princess/leader, but more of the TITLE that Celestia had given her: Princess Twilight Sparkle.
I actually see her becoming a fantastic leader over Equestria as time go by. She will definitely have acquired more knowledge of magic, friendship, and even leadership than Celestia several years from now. I can see her as the greatest leader that Equestria has ever known, no doubt about that!
So...why does she need to have the title as "Princess"?! The title "Queen", "Ruler of Equestria", or "Ambassador" would make much more sense to me!
You see, nowadays when most people, especially young girls, think of "princess", they think of the "Disney" princess archetype. Many say that they are not at all role models to be followed, that they hardly ever take their own responsibilities and just look for a "knight in shining armor" to come save them.
Nobody thinks of Twilight as that kind of person...ur...pony. She's the opposite! She takes action, gets things done, is extremely organized, and becomes wiser and wiser all the time. And she was given the title of princess by someone who, many can agree, never seems to do anything except raise the sun, give simple advice, and just be a mentor/teacher. This isn't to say that Celestia is completely useless, but we always root for Twilight much more than Celestia when it comes to saving the day. In fact, Celestia is always the damsel in distress, while Twilight is the "knight in shining armor"!
Anyway, it's safe to say that I'm getting more and more used to seeing the wings on Twilight, symbolizing her new status as princess. So I'd really like to see Twilight do three things before the whole series ends...
Get married (not to Flash Century!) to someone compassionate, understanding, wise, a great leader, and a bit of bookworm like her. Take responsibility over her own land/empire. Yes, that would be awesome! Combine all her findings on friendship and make it into a sort of magnum opus of Equestrian Literature!
Let me know what you think.
