"I want you to forget about me and leave me alone, until I say otherwise. But Iíll never forgive anyone tries to apologize to me one more time. Have fun at the wedding everypony and enjoy your friendship while it still lasts. I know mine did.Ē
— Twilight, delivering her ultimatum at the end of Chapter 1.
"Bitterness" is a My Little Pony: Friendship Is MagicFan Fic written by PLCTheCd. As for what it's about, consider the following:Remember how in "A Canterlot Wedding Part 2", the entire "Twilight being dissed" subplot was resolved by only having Applejack apologize to Twilight? And Twilight was willing to accept it?What if she shot it down?Despite Chrysalis still being defeated as in canon, Twilight is unwilling to let this go. She is perfectly willing to cut off ties with her friends (and mentor) over this whole ordeal. The question is, will she?Despite only having two chapters currently, this fic is yet another interesting take on addressing the problems of "A Cantlerlot Wedding Part 2", and unlike like other well known ones, has Twilight reach her breaking point through Applejack's apology. It really is a fascinating take on things.
This fan fic provides examples of:
Aesop Amnesia: Twilight accuses the others of this, due to them not living up to their promise in "Lesson Zero" (which was to listen to and consider her concerns, no matter how trivial they seemed).
All Take and No Give: Twilight accuses the others of only caring about what they can get out of their relationship with her, claiming she should have recognized this back when they all wanted tickets to the Grand Galloping Gala.
At Least I Admit It: When Celestia tells Twilight that she's doing exactly what Discord wanted by tearing the group apart, Twilight nastily replies that at least he was upfront about that.
Bribe Backfire: Pinkie's offer to throw a big apology party for Twilight only causes the unicorn to accuse her of trying to bribe her. Similarly, Shining Armor trying to invite her to participate in the wedding is rejected and treated like another 'obvious' bribery attempt.
An unintentional version, but given the tone of the fan fic, this must be pointed out: After Chrysalis inputs her two cents on how Twilight was treated, she (sarcastically) comments "With friends like them, who needs enemies?"
And an intentional version. Twilight redirects Shining and Celestia's remarks towards her, just to twist the knife at how badly they screwed up.
Twilight claims she should have realized the others were selfish after how they reacted when Celestia first sent her tickets to the Grand Galloping Gala.
Cutting the Knot: Defied. Spike tries to get Cadence to use the love spell on Twilight to get her to listen to reason, but it doesn't work.
Cadence: I canít, Twilightís too heartbroken to be fixed by my spell. I can only restore her heart when she wants to be loved by all of you again. Iím afraid at this state, she wants nothing to do with us.
Deconstruction Fic/Fix Fic: While this was intended to be the latter, it feels more like the former. Once Applejack delivers the apology, Twilight reflects on what has transpired, and rejects it.
Disappointed In You: When Spike points out why he didn't defend her before, Twilight simply looks at him with disappointment rather than resentment and says he should "think for [himself] next time."
Twilight, in her rage, keeps calling the others hypocrites.
Her absolute refusal to listen to anything they say in their defense, twisting it around to try and make them come off even worse, doesn't seem all that different than the incident that set all this off in the first place.
Unreliable Narrator: Twilight's view of the others is subtly twisted to comply with her new, darker take on them. For instance, when faced with her brother's tearful apology, she decides he must have mastered crocodile tears rather than acknowledging it might be sincere.
