Because Celestia did tell her, through song, we’ve seen in every song other characters, without the slightest bit of context can jump in and understand the situation and join in on a song to music that is somehow playing. So as Celestia was singing she was communicating her meaning as though she was just telling her, it’s a time saving device.

In that case wouldn´t that make Twi´s friends, Spike adn Celestia even worse than Twi?  
I mean all of them, really ALL of tehm, were compltley okay with Twi suddenly vanishing after they left her.  
With her not coming to the wedding.  
With her not being seen ANYWHERE in the castle or canterlot.  
They were having fun on a stranger´s wedding who they had never seen till yesterday.  
They were fine with a completley crushed Twilight who could have done to herself who knows what after being told by her brother to not show up at his wedding.  
For them everything else but Twi was more important.
 
Now i don´t know what friends you have, i don´t know how you treat your friends or if you even have any.  
But if you got even one friend and you make a mistake and then see your friend leaving you when you need him the most, to enjoy himself, not giving a damn about you, your feelings, your fears, your dreams, etc., what would you feel?
 
Really, Twi made a mistake but it is understandable cause as you said yourself it was clouded by emotions.  
Same for her friends who chosed attending a wedding over trying to understand and help out their friend (And that after that lesson zero lesson <_<).  
But you know what? They forgave each other. And are still friends despite all that.
 
I dunno about you, but if my best friend starts behaving like that and tehn getting served like that by somebody else, here SA, then i would give him a chill pill and find out why he acted so madly. And whn i find out, try to help him.  
Not just toss him aside to get wedding cake or to wear some fancy dress.
 
It´s not only Twi, you can say something bad about every chara in the show and turn them into a unlikeable chara like you do.

@Godzilla:  
The moderation team are not your personal army. You do not get to threaten to “have us” do anything - we are not here to serve your whims and all your bluster is only going to prejudice us against you. If someone is breaking the rules, report them and wait for it to be dealt with.
 
@Everyone:  
Seriously, calm the hell down. Develop thicker skins and don’t feed the trolls.

@Niggoslav_Krawczyk  
Your point?

@Background Pony  
Exo-Squad, She-Ra, Robotix, and Spiral Zone were also created to sell toylines.

@TaraCallie  
This guy is either looking for attention or incredibly mentally unstable. In either case we should probably leave him alone and tbh I think he left already.

@TaraCallie  
*asinine.

@Background Pony  
The only idiot in this room is the Background Pony taking what other people like as a personal insult.
 
You’re just an unpleasant person. You think you have the right to insult people for liking something you don’t like? You’re just a bully. A sad, pathetic bully.
 
At the end of the day, we’re all watching My Little fucking Pony. A show that all of us are too old to be respectfully watching. Someone could catch us watching this and say “That’s kinda sad” and we’d have to agree with them.
 
We;re sitting here and discussing a children’s cartoon and it’s ethical meanings that we pull out of our ass. That’s silly and our time better is spent elsewhere.
 
But you come in here and act all high and mighty because your PERCEIVE the later seasons and Equestria Girls as bad, and through your own toxic version of logic think that anyone who might enjoy it is some lower form of life?
 
You know what? Fuck you. Grow the fuck up, pull your head out of your ass, and fuck right off. If you hate the goddamn show so much, get out and let us enjoy our ponies in peace you asanine little bastard.

@NoHooves  
I can see it now.
 
Celestia looks down at the broken form of her former pupil, after having defeated her in a heated duel and says “You were my sister, Twilight. I loved you…”

@Background Pony  
Also how they always make her right even when she’s wrong.  
Just because it turns out Cadence was being impersonated is no reason to assume she was right all along. She may have come to the correct conclusion, but her reasoning was flawed and coloured entirely by emotion. What if Cadence wasn’t impersonated? What if Twilight actually had just called her brother’s fiancee evil without any proof?

@Mayojar77  
Yeah, I really feel that the writers have recently been trying to turn this into “The Twilight Sparkle Show”, and have been slowly exaggerating the characteristics of the rest of the Mane 6. They’ve also seem to be putting to much focus on her character with things such as her being the only pony to try and find the Crystal Heart, while the others got involved in comedic antics, as mentioned before, her being the only one worthy enough to be crowned a princess, and the only pony who went to the human world in Equestria Girls.

@NoHooves  
Either way, she’s coming off as the least worthy of the Elements of Harmony with every episode that focuses on either her or her reactions.

@NoHooves  
That’d be awesome

@Mayojar77  
…I REALLY doubt they’re trying to turn her evil or whatever.
 
 
Hey, if they are, it could make the coolest story arc we’ve had in a while.

@Background Pony  
No. It really started around when she started being a hypocrite and a sociopath.

@Mayojar77  
I wouldn’t say that. Did you just dislike Twilight from the beginning?

@Background Pony  
Or Rainbow Dash. Or Pinkie Pie. Or Rarity. Or Fluttershy. Or Spike. Or Fanon Lyra. Or Fanon Derpy. OR Big Macintosh. Or Applebloom. Or Scootaloo. Or Sweetiebelle. Or Cheerilee. Or literally any other resident of Equestria.

@Background Pony  
I’d like to see Princess Applejack

@Mayojar77  
Exactly. Heck, going by the show’s logic, the pony who expresses all of the qualities of the elements the most would probably be Applejack.

@Background Pony  
“Artistic integrity”? Dude, MLP is not for you. I’m surprised someone with your attitude ever got interested in watching a TV show based on a toy line in the first place–or a TV show at all. ALL television is like this to some extent.

@Background Pony  
No, I’m not any of those things.

@Background Pony  
You’re either wrong or right.

@Background Pony  
I’m not wrong nor am I right.

@Background Pony  
Hey, bludgeoning artists until they crack or put out better content is what I do!  
I’ve gotten a lot of upgraded resolution pictures that way!

@Background Pony  
That’s because you’re wrong.
