Her flaws in Season 2 were started in Season 1, although Season 2 is where her flaws started causing conflicts on a regular basis, unlike Season 1 where they were mostly portrayed as cute character quirks.
 
The one notable exception was in Feeling Pinkie Keen, where Twilight Sparkle’s insistence that everything have a logical explanation put her into conflict with Pinkie Pie. For me that episode is just as much about Twilight’s personality as it is about Pinkie’s, and that’s probably why it’s one of my favorites in Season 1.

Twilight Sparkle was always a flawed character. Admittedly, she was never more adorable than in Lesson Zero, but it wasn’t like that episode suddenly made her flawed and loveable.
 
She’ll be fine as an alicorn. If anything even more loveable.

Feel free to list all of them.
 
Or wait for the fucking episode and not think about it too much, or responding.
 
It’s kind of your choice.

…OR becoming a princess could give her a whole new set of internal challenges and help her grow as a character in ways we haven’t begun to imagine.

I think you worry too much, OP.
 
Take a deep breath and simply enjoy the show
 
_{uuuuuuuuuuummmmmmmmmm}

By “update the language” I don’t necessarily mean we should include characters like S1 Twilight Sparkle under the Mary Sue banner, but rather that we need a better term to define characters who suffer from being so idealized that they are uninteresting.

@Shin32  
We probably need to update the trope language to include characters who are simply too idealized and are ultimately boring due to their lack of legitimate flaws. It’s not extreme enough to be a mary sue since they do not break the reality around them, but they are too “squeaky clean” to make people feel legitimately invested.

@Background Pony  
To me, the whole “plot warp and bends to” criteria is what truly makes a Mary Sue and what makes one so despised, because it definitely is possible to make a beautiful or powerful character with few flaws and find ways to make them likeable or have them work in a story (ie. Belle from Beauty and the Beast or Hiko Seijuro from Rurouni Kenshin).

If I had to take a guess at how the episode turns out, Twilight willingly giving up her princess powers is actually some final test before starting on advanced magic training or w/e.

I think the fears of this anon are legit because they match my own. I won’t call twi a sue, but I think I can be confident she has some qualities of a sue.

A mary sue is something that is to perfect anon. Someone who everyone likes NO MATTER WHAT. Somebody who the story itself warps around and bends to even if they aren’t the main character. Somebody who has no character flaws external or internal and is good at pretty much everything. Other characters only exist to tell them just how awesome they are, and how much they suck in comparison, even the villains.
 
Twi is no sue.

I think if its permanent, it will just add to her learning and character developing
 
Give her time

Probably because noone there would listen to him.

Because since we have the ability to talk through this magical boxes debate is possible?

Mary Sue is used so much nowadays that it’s kind of lost it’s meaning.

Anon, there are FORUM boards for these kind of topics. Why do you not express your opinions there?
