Heres the contectquote from the author at the source  
Its the scene where after the Elements of Harmony, supported by cartoon friends and loved ones who have searched all over Equestria for Twilight because they assumed Discord had taken her(which he did not), have brought the Spirit of Chaos and Disharmony back into stonemuch to the agony of dear Twilight Sparkle, considering she was Discords best friend. His only friend
 
Angered, fueled by rage and hatred toward her friends, she lashes outespecially on a poor bluejay who has a HUGe secret crush on her and never gave up trying to play her hero.
 
 
Heres the excerpt from that chapter:
 
Despite the cheers and applauses around her, especially words of praise and joy that she was saved, Twilight paid no attention. Her face remained expressionless, almost lifeless.
 
Sweetheart, we did it! Baldwin cried as she watched him come his way. He spread his arms apart for her to rush into them. Give your sea daddy a hug!
 
But she didnt. She passed him as if she hadnt even heard him.
 
Despite his slightly mixed emotion of confusion and hurt as he realized Twilight had brushed him off during this moment of triumph, Baldwin watched as Twilight continued her small trek.
 
The unicorn slowly came to a stop where Discord stoodnow here he laid.
 
Stone.
 
Mordecai smirked proudly, gazing at the ugly, stoned face of Discord himself. He did it, they all did it. Discord was stripped of his powers, and he was back to where he belonged for good.
 
And best of all, Twilight was finally away from this monster that had taken her away from them. From Mordecai.
 
The bluejays smile grew wider as he turned to see her suddenly stand beside him, thinking now that Discords grasp on her mind was over with and she would come to the bluejay with everlasting thanks and gratitude for his bravery to fight just for her. Maybemaybe she would even thank him with a kiss?
 
But the look on her face made him raise an eyebrow. And he was even more surprised when she bent down to Discords imprisoned figure. His eyes widened when her hoof gently touched the creatures stone face.
 
Hehe Twilight choked on her words as more tears slid down her cheeks.
 
No need to thank us! Rigby said modestly as he passed through the others and stood beside Twilight. Really, this harmony stuff wasnt even hard! And he let out a laugh as he placed a friendly arm around her trembling body, completely oblivious to her pained expression. So looks like youre okay, and were okay! He raised a fist and hooted. We should so throw a party!
 
Ooh! A party! Pinkie Pie clapped her hooves. Well call it a We-Beat-that-Big-Fat- Meanie-Discord celebration, and itll have cake, balloons, oh, and streamers! Definitely streamers!
 
Twilight didnt even hear either of them. Her eyes gazed into the lifeless ones of her dear friend.
 
Discords expressionpain, misery, loneliness. She gazed at the calm yet painful expression on his face. It was as if he was saying goodbye
 
Twilights heart plummeted deep in her chest as her hoof never left his face. How she wish she could feel his fur againsee his smilehear his laughfeed his hunger for life itselfcontinue hanging out with her best friend
 
Before Rigby knew it, his tail was violently grabbed by a blazing red aura and was flung across the street, crashing into a few ponies, one of them especially Pinkie Pie.
 
Hey, what gives? Pinkie Pie asked in utter surprise as she picked herself up, gazing at Twilight with confused blue eyes.
 
What the heck? Rigby demanded as he raised himself from the ground.
 
However, his anger immediately diedTwilights anger was just as terrifying right now that it made him tremble and hide behind Pinkie, who was beginning to shudder at the sight of her friend.
 
The unicorn bared her teeth, her eyes blazing with both fire and tears as she glared at everyone, especially her five friends.
 
HOW COULD YOU? She demanded angrily.
 
How could we what? Fluttershy gasped, trembling at the sight of her enraged friend.
 
Oh, dont lie to me, Flutter-rage-is-my-thing-shy! The unicorn spat, glaring daggers at her. You know, I dont regret using that memory-erasing spell on you anymore!
 
Fluttershys eyes widened a bit, though she was still confused.
 
However, she was hurt by her comment.
 
Memory-erasing spell? Rainbow Dash questioned.
 
Well, you dont need it! Twilight shouted, nearly scaring her off her hooves. You were so good at forgetting things! Especially about Discord himself!
 
Twilight, what is wrong with you? Baldwin exclaimed frantically, removing his helmet and adjusting his glasses to gaze at the enraged pony that was his daughter figure.
 
I should be asking you all the same thing! Twilight shouted as she rushed back to Discords side. You! All of you! You did this to him!
 
You make it sound like its a bad thing! Ruff shouted.
 
It is! Twilight sobbed, her anger just temporarily dying down as the emotional pain pang her heart even more. I was never corrupted by him! I was never kidnapped! She stared at all of them, her eyes running with tears. Didnt you even read the note I left?
 
Note? Spike asked in disbelief. What note? He felt his tail twitch, and his green eyes widened a bit, and suddenly, he felt a bit nervous for some reason.
 
The note I left on my desk! She cried.
 
Rockys eyes widened in realization before she dug into her pocket. She held the tiny piece of charred paper with Discords name on it.
 
Then she looked over at Spike, whose expression held one of utter horror as well as self- shame.
 
Oh, no Rocky gasped.
 
So wait Pinkie Pie racked her brain. Discorddidnttake you? She blinked in confusion, staring at the sobbing unicorn.
 
No, you sad excuse for the Element of Laughter! Twilight cried.
 
Pinkie Pie felt her hair deflate a little as soon as Twilight said that. Her bottom lip quivered and her blue eyes glistened, threatening to shed tears. However, Twilight could care less about her sensitivity right now. Same went for Fluttershy, who was just as hurt from one of Twilights recent comments.
 
She didnt care what they were all thinking. She felt she couldnt care about them anymorenot after what they had done to her best friend.
 
Before any of the elements knew it, painfully ripped from their necks were the powerful necklaces, all taken off by the violent use of Twilights magic. The unicorns tears never ceased as they all floated above her, close to the crown on her head.
 
I hate all of you! She shouted angrily.
 
Mordecai could not believe what he was hearing as he stared at her. All of thisall the trouble that had eruptedwas from one single misunderstanding?
 
So Twilight had not been kidnapped?
 
Discord never penetrated her mind?
 
If Discord hadntif Twilight was never reallythen did that actually mean?
 
He didnt have time to think when Twilight wheeled toward him. He could only tremble as he saw the fury in those usually pretty eyes of hers.
 
I hate you, Mordecai, she spat coldly.
 
Suddenly, it felt like a his whole world had been shattered as soon as she said that. His heart had broken in pieces as her words echoed into his ears, and Mordecai felt like the object of hopes and dreams had fallen from a high shelf in the back of his mind as he could only regard the furious unicorn with pained-stricken eyes and a quivering beak.
 
Ouch Rigby winced. There is nothing worse than having the girl you like tell you she hates you.
 
What? Baldwin wheeled toward him in utter confusion.
 
Twilight sniffed, knowing she couldnt stand another minute being among thesethesemonsters.
 
Using part of her magic, Twilight took hold of the statue of Discord and brought her close to her side. This sight made Mordecais heart crumble even more if possible.
 
T-twilight He swallowed hard, a huge lump in his throat as his arms felt weak.
 
She continued glaring at him, then gazed back at the face of Discord, her expression temporarily mournful. He was myweI Her voice trailed.
 
But Mordecai didnt even need to hear it. He knew too well what she was going to say.
 
She loves him, he thought painfully, no love spell had been neededit was real this whole time. This whole freaking time.
 
Margaret watched the pained expression on him, and she couldnt do anything to fix it now that Twilight told him the undeniable.”
