Alicorn or not, Luna with the book at the end kinda convinced me.

AH! Each episode of the DVD relates to gaining a new power or some sort of… Important event. (The hourglass thing in It’s About Time foreshadows… Something– The ulterior theory is that immeasurable fandom influence may write Time Turner into an episode if not a full-on special.)
 
Those Twi, Rainbow, and Luna episodes seem important, therefore… Er, conjecture, lol. I couldn’t say for sure what it means, but I’ve a strong-ass feeling within me. I won’t go into my feelings on spiritualism, but I digress. ;)

Hey, you know, since we’re into crazy theories here…maybe….just maybe….Twilight will be sending her friendship reports to Princess Luna because she needs them more than Celestia?

Hmm…you’ve got an interesting theory there, OP. Colour me intrigued…

@Ferrotter:
 
xD
 
Let me rephrase the question:
 
What could Luna possibly teach Twilight that are not naughty(implying that she knows naughty things at all)?

There are things I’d like to learn from Luna.

I don’t know.
 
>Like they’re trying to imply something to the audience
 
What that scene made me think is that Luna is skeptical to Twilight’s abilities.That,and she seems to be at least worried that Celestia is sending someone that Luna might consider not yet ready to go.This goes for Cadence and Shiny as well,in fact,how can we know there were talking about only Twilight at all? sure Celestia said to Twilight that this was a test for her,but they could also be talking about Cadance as well.
 
Another thing: What could Luna probably teach Twilight?

I like this theory. A lot!

Besides, those wings look like those of Luna or Cadence copied and pasted onto Twilight.

I don’t think anyone messed up anything. The wings on the toys and poster were very noticeable like they were making sure they could be seen, and most products must meet qualifications before they get sent into public, plus the wings on the Twilight plushies could easily be removed without remaking the whole thing. And this is a tv show, they think everything in advance which most likely means this has been planned for a while.

Da. Is good theory.

Magic? More serious lessons in life? Not sure, it’s just a theory.
 
Also, yeah, I just noticed that goof. Gosh, I’m tired. However, I don’t know how to update the image to fix it.

It certainly beats Twilight Princess.  

well the word is plausible…sorry just had to correct it
 
But maybe plausible I don’t see why Luna would have to teach her anything though

I don’t have a clue but this is definately an interesting theory
