What's in the box?

The box shown in Princess Twilight Sparkle - Part 1 and Part 2 have created several arguments and discussions since appearing. Why did the box appear? What's inside the box? Why does it need six keys? So on and so forth. This blog here is my version of what is and what is to come. Whether or not you accept it as fact is up to you. I'm only writing this for my benefit and to see if anyone agrees or sees something new.

The six ponies and keys

So far, no information about the box nor about six keys have been revealed yet in the show. However, I have a hunch that it's much closer than most people think.

Each pony represents an element of friendship: Honesty, Kindness, Laughter, Generosity, Loyalty and Magic (or Friendship, if that's what you prefer). These elements have been put to the test time and time again and every time they mostly come to the rescue. For the most part, however, these tests have been for something not directly affiliated with their element or they have had the help of the others. My theory is that each pony must face someone or something that directly attacks their element and they must face it on their own (for the most part). An example of this would be the most recent episode (as of writing this), Rarity Takes Manehattan.

In the fashion show, Suri Polomare takes advantage of Rarity's generosity and uses it against her, taking her fabric and making a dress line almost exactly like Rarity's. In retaliation, Rarity uses her friends to make a whole new line within a night and complains about "how generous she was" for bringing them to Manehattan whenever they want to do something else.

Now, at this point it boils down to psychology about why this happened and why this is relevant. To put it shortly, on the Enneagram test, Rarity is a number two: The Helper. When she is growing as a character and relaxed, she is generous, loving and humble. You can see that at the beginning of the episode, especially during the Generosity song. However, when she is stressed, she becomes manipulative and uses her generosity against her friends, as told in the paragraph above. This is why the two extremes were apparent in the episode.

At the end of the episode, Rarity receives a spool of rainbow thread from Coco Pommel as apology for how she treated Rarity. This in itself is a key to how it's a key (yo dawg.), but that will be explained later. For now, let's go to what the episodes are to tell us.


Well, this section will be a little messed up because I have changed my thought process since starting this.

Original theory

My original theory was based on the Daring Do book given to Rainbow Dash being one of the keys. With that in mind, there is a span of four episodes between Daring Don't and Rarity Takes Manehattan, Daring being the fourth and Manehattan being the eighth. Following that process, the episodes where a key would be found would be every fourth episode, so it would be twelfth (Pinkie Pride), sixteenth, twentieth and twenty-fourth. This would leave the last two episodes for the finale and give enough time for each discovery to take effect.

Also following this, the order of which pony would get a key would follow the order of the elements stated in Friendship is Magic, part 2 in reverse order (minus Twilight Sparkle, who would more than likely get hers last): Loyalty, Generosity, Laughter, Kindness, Honesty and Magic.

New theory

My new theory is based on the book not being the key and Rainbow not receiving her key yet. In this new theory, Rainbow would get her key in Rainbow Falls (episode ten) and Pinkie would still get her key in Pinkie Pride. I don't believe the process follows that of the previous theory, as that would leave the last episode of finding keys on the eighteenth episode. However, what brings me to this new theory are the titles itself and how Daring Don't doesn't attack Rainbow's element to the core. For reference, Rainbow would be a number three on the Enneagram (The Achiever) and Pinkie would be a seven (The Enthusiast).

To the core, Daring Don't shows how much Rainbow can idolize others and undermine herself. Unfortunately, based on the Enneagram, Rainbow should have taken advantage of that situation and made it to make her seem more important and successful, which she inevitably didn't. Based on this and the Rainbow Falls summary, Rainbow Falls sounds more suitable for what can happen when Rainbow is under a lot of stress.

Speaking of Rainbow Falls, the titles of the episodes caught my attention. Rarity is the element of Generosity; her episode is titled Rarity Takes Manehattan. Rainbow Dash is the element of Loyalty; her episode is titled Rainbow Falls. Pinkie Pie is the element of Laughter; her episode is titled Pinkie Pride. Notice the running theme? Each episode name directly attacks the element of the respective pony and the name of said pony is also featured in the title. With Rarity, she's taking advantage of her generosity. With Rainbow, I speculate she falls from her achieved position and takes advantage of the other team to make herself look more successful. With Pinkie, I speculate that she will pride herself too much on her partying abilities that she will forget what the party is actually about. I can only imagine what the other episodes are titled.

What's inside

Probably the biggest question to surface is "What's inside the box". While I am unsure what exactly is in the box, I propose that it's a sort of Rainbow Power kinda thing, much like the Rainbow of Light from the first generation of My Little Pony. What makes me propose this is the recent merchandise being sold by Hasbro, the Rainbow Power toys, as well as the fact that rainbows are a huge part of the show, including all of the Element of Harmony final attacks, the Rainbow of Light as mentioned before and the spool of thread given to Rarity. Again, I am severely unsure of what is truly in the box. This is just my take on it.

Why do this?

Castle of the Two Sisters S4E03

My kingdom. My home...

Another question is why the mane six are on this quest. For the most part, that won't be explained until the season finale, or at least not until much farther into the season. But once again, I have another hunch. Based on one of the commercials commonly shown advertising the show, the announcer states that the ponies go "on a new quest that could change the destiny of Ponyville forever". While this doesn't say much in context, I believe that this quest will bring Twilight Sparkle to her true princesshood, her castle being the Castle of the Royal Pony Sisters and her friends becoming her loyal companions, allies and soldiers (soldiers doesn't sound nice, but that's what I figure currently).

My reasoning for this is that they are currently taking care of the castle and visiting it more often than they used to. Considering it used to be an actual castle where Celestia and Luna lived and ruled over Equestria, it takes no stretch of the imagination that it can be revived to be a proper castle. Also, the Tree of Harmony is underneath the castle and will need protection (maybe?), so obviously the wielders of the Elements should watch over it.


Welp, that was long. If you've come this far, congratulations and thank you for taking the time to read. Feel free to state your thoughts and argue with my process if you want. Debating is always so fun when not done by yourself :P



So after watching Rainbow Falls, I feel like my theory so far is of true sound with the Wonderbolts medal she got with the award for the qualifications the "key" that she needs. I'm glad I'm right so far.
