Finally fed up with a lot of fans loving a reform Sunset more than the evil Sunset, Sunset Shimmer officially loses every little patience with her present self and wastes NO other time but calling HER out for, not only for being rushly reformed and for Twilight Sparkle getting off the hook, but CHANGING her entire character in the first Equestria Girls movie so she can become a better person.

Here is the prologue. Also, this is the LONGEST conversation.. ever.....:

Present Sunset Shimmer: Gotta run. I volunteered to show some new students around the school. Thought it'd be good for them to get to know the new me...... before they heard all the stuff about the- [Unfortunately, Sunset Shimmer STOPS Present Sunset Shimmer in full speed while she emerges from the portal and furiously confronts her, whose VERY ticked off at her]
Sunset Shimmer: Sunset.... What the FLAMES do you think you're doing?!
Present Sunset Shimmer: Who are you?
Sunset Shimmer: Don't "Who are you?" me and STOP being so you! It's not fair! Every time someone who were a villain like YOU regret your past mistakes and just wanted some friends and a redemption, Twilight Sparkle ALWAYS get her way! (In a mockingly tone) "The magic of friendship doesn't just exist in Equestria. It's everywhere." Well, guess what, I'm SICK of it!
Present Sunset Shimmer: You are?
Sunset Shimmer: YES, AND I'M SICK OF IT! And I still have NO reason why people who watched this show are still continuing to LOVE the new you more than the old me, the CLASSIC Sunset Shimmer!
Present Sunset Shimmer: Look, I know your upset, but... you just need accept it and make left turn. People like the new me than the old me.
Sunset Shimmer: The old me?! Is THAT it, huh?! YOU REALLY THINK YOU ARE SO MUCH BETTER THAN ME?! WELL YOU'RE NOT OKAY!!! You know.... I usually have a lot of fans that like me when I'm so popular, but when you came along while your reformed, you just come on it and TAKE IT AWAY FROM ME! I mean.... COME ON! You just ALWAYS had to play the hero, do you?!
Present Sunset Shimmer: I was trying to change my ways and to better myself!
Sunset Shimmer: You never change your ways and better yourself! Not in any way that would put you to be Twilight's student in your whole life!
Present Sunset Shimmer: What makes you think that I didn't have a change of heart the whole time?
Sunset Shimmer: [In utter fury] BECAUSE I WAS LYING TO EVERYONE WORLDWIDE, OBVIOUSLY!!!!!
[Long pause]
Present Sunset Shimmer: What?
Sunset Shimmer: Yes! YOU heard me! She's the one I saw running away after she became princess of the Fall Formal while the rest of the students turn against me! And guess what, Twilight DIDN'T ran away from the human world, just so you can stay here and have your friends looked after you, she ran away from YOU!
Present Sunset Shimmer: Hey! Don't say that! Twilight is a princess in Equestria and an expert in friendship magic! Magic came into this world when I stole her crown. It's taken a lot for me to earn everyone's trust.
[While Present Sunset Shimmer was saying "It's taken a lot for me to earn everyone's trust.", Sunset Shimmer was mocking her by mouthing her words]
Sunset Shimmer: Ah! See?! THAT'S exactly what I'm talking about right there! I can't believe you sold my hopes and dreams on becoming a popular queen just so you can embrace the magic of friendship, change your ways, and hang out with your stupid friends...
Present Rainbow Dash, Present Applejack, Present Pinkie Pie, Present Fluttershy, and Present Rarity: [Off-screen] HEY!!!
Sunset Shimmer: ...than getting back at that insensitive jerk who ruin YOUR reputation so you can get a radical future by the end! YOU'RE PLAYING FOR THE WRONG SIDE, DUDE!
Present Sunset Shimmer: Why would I be playing for the wrong side?
Sunset Shimmer: Because playing for the wrong side and changing your ways on becoming a better person is NOT COOL!
Present Sunset Shimmer: Okay, okay. Calm down....
Sunset Shimmer: Don't tell me to calm down! What's more personally for everyone else than this stupid friendship?!
Present Sunset Shimmer: I know this looks bad, but you have to accept who you are and try to become a better person just like me!
Sunset Shimmer: Oh, because I need to follow you everywhere you do?!
Present Sunset Shimmer: But I didn't mean it that way. You always said you didn't understand about things like that...
Sunset Shimmer: STOP JOKING AROUND! What I understand is that Twilight Sparkle TOTALLY humiliated you and COMPLETELY put you at risk! You never even know what's going on, and that's what I'm for! [Breaths heavily while she brushes her hair back, restoring herself from the process] Now... what I was trying to say is, just revert back into being the old you so the whole students can love you again.
Present Sunset Shimmer: But I've changed!
Sunset Shimmer: What did you just say?
Present Sunset Shimmer: I said: I've changed! And I will never be the bully again because I changed my villainous ways a decade ago, Twilight Sparkle was right, I showed everyone who I really-
Sunset Shimmer: Twilight Sparkle was right?.......
[Sunset Shimmer laughs shaky and uncontrollably. Her hair fell over her forehead as she looked down while she continues laughing like a psychopath, to Present Sunset's horror]
Sunset Shimmer: [She snaps, gets close to Present Sunset Shimmer's face] TWILIGHT SPARKLE GETS EVERYTHING SHE WANTS!!!!!! [Takes deep breaths, trying to calm herself down] But NOT this time... This time, I am going to win! I AM going to burn them all! I'm going to create a better future, and I don't care what it takes! My past IS today, and I ONLY wanted to become princess of the Fall Formal so I can be the most popular girl while the rest of the CHS students cheering for me like I'm a queen, you don't deserve to be redeemed to early and be forgiven because of that sparkle face. [walks towards the door]
Present Sunset Shimmer: Hey? Where are you going?
Sunset Shimmer: (sighs) Where am I going? I'm going back to get revenge on Twilight Sparkle.
Present Sunset Shimmer: But why?
Sunset Shimmer: Because I am NOT letting her get off the hook completely after what she did to me, and I'm going to accomplish my mission so you won't be reformed too fast anymore. [Opens the door] That's what villain protagonists and determinators do for each other.
[Sunset Shimmer closes the door, exiting her way out]
Present Rainbow Dash: ......Awkward.....
Present Sunset Shimmer: ....Who was that?.....
Present Pinkie Pie: .......She's psychic!....
Present Applejack: ...Uh-huh. If you say so.......
