Just another thank you for everyone that watched, favored, criticized, watched, etc. With al of that out of the way, let's conclude this madness!

The weeks after Twilight put her mentor in the worst kind of spotlight went by too fast for her to comprehend. Princess Luna was tasked with not one, but three trials, which had fairly important mares on trial, all of which were overwhelmingly ruled guilty, and all had a secret draconian punishment added to the sentences for good measure. Princess Celestia was found guilty of violating her mandatory medicine prescription, with hefty evidence suggesting that she felt she was "seeing things clearly for the first time!" She got a month of community service, with the Royal Guard watching her closely from then on, making certain she takes her medicine.
Mayor Mare was was found even more guilty, charges being money laundering, embezzlement, gambling with taxpayers' bits, tax evasion, financial fraud, bank fraud, mortgage fraud, medical fraud, forgery, and counterfeiting, amongst the ones she was convicted of. Her first year would consist of repaying Ponyville for all the money she had leeched out of it. After that, life without parole.
The final trial, of Pinkamena Diane "Pinkie" Pie, was all too bitter a pill for her and her friends to swallow(except Rarity, who kept a picture of her ravaged house as an easy transformation from a tragic court ruling to a birthday party on Hearths' Warming Eve in Canterlot.) Found guilty on Destruction of Property and Hoarding of Volatile Chemicals, Pinkie was sentenced to only a month of community service(given her personality), and she was forever banned from power plants, role-playing, and clothes, until the end of time.
And while it wasn't de jure, the sentence of Apple Bloom was drawn out and merciless, with her entire family guilting her about her antics until Applejack inflicted the coup de grace upon her little sister. "More tea, everypony?" Apple Bloom asked the four mares, and Spike, sitting around a rectangular table in Twilights' House. She asked this in a defeated, slightly contemptuous tone, since she was dyed purple, with her mane green.
"Don't mind if I do!" Spike said, grabbing a tea cup.
"Spike!" Rarity scolded. "Be more polite to our waitress! Thank you Mizz Apple Bloom"
"Rarity, don't waste time bein' formal with Spike II!" Applejack scolded, content with the water bottle by her side. "She's grounded."
"Oh." Rarity said, conflicted about what she would do if Sweetie Belle went rogue. She then decided. "Don't mind if we do!" and conjured a cup towards her, and another towards a scarlet-faced Spike.
Rainbow Dash and Fluttershy walked over to get their tea, secretly thanking Apple Bloom, by her name, outside Applejacks' earshot. Soon afterwards, Twilight walked in, accepting tea from Spike II. "Thanks for the extra help, Applejack," the violet unicorn said, "but do we really have to not thank her and call her Spike II?"
"Welp," Applejack replied, "it was either this, or beatin' her. Ah gave her a choice, so if anythin', Ah was bein' civil!"
"Well, our mentoring methods seem to differ..." Twilight said. "Spike II, take a note!" Spike II sighed as she walked over to a table with a pen and a scroll. "Dear Princess Celestia, the time spent yesterday in each others' horseshoes has been both the best and worst days of our lives. Regardless, it was the most illuminating day of our lives as well, for we have learned what you wanted us to learn all this time: that you are a batspit-insane abuser of power, and Equestria would be much better off with a parliamentary system, complete with a prime minister- specifically, me!"
"Uh, Twah?" Applejack interjected. "Pills or no pills, the Princess is goin' to hunt you down after she reads that."
"Hmm, you're right." Twilight responded. "Spike II, destroy that letter!" Apple Bloom complied. "Now write a new one." She complied still. "Dear Princess Celestia, the time spent yesterday in each others' horseshoes has been both the best and worst days of our lives. Regardless, it was the most illuminating day of our lives as well, for we have learned what you wanted us to learn all this time: that role-playing is a great way of ponies teaching lessons for misbehavior! Here's hoping you follow by your own rules. Your Most Faithful Student(All four of those words start capitalized, by the way), and her friends -Twilight Sparkle(and her friends)."
Apple Blooms' penmareship was above average compared to most other fillies at her school, but she was no Spike. She also couldn't breathe the letter to the paroled Princess of the Sun, which she realized fairly quickly. "Twilight?" she asked. "How do I send this letter to the Princess?"
"Don't worry Appl-" Twilight stopped to catch Applejack shaking her head disapprovingly. "Uh... how the hell do I know? Walk?" She looked back at Applejack, who was nodding like a strict teacher would to her pet.
"Come on, Spike II!" Applejack ushered her little sister out the door. "Ah'll walk ya to her." She then whispered in the equine dragons' ear, "Can't have ya runnin' off for more booze, now, can Ah?"
As the door shut behind the two, Rarity turned to Twilight. "I must thank you again, Twilight, for letting me stay in your house while mine is under repair."
"It was our pleasure!" Spike said, quite enamored with this arrangement.
"Aaaanyway," Twilight intervened, "Who gets to fix your house?"
"Why Princess Celestia, of course!" Rarity exclaimed. "And Pinkie Pie! And Apple Bloom!"
The purple earth pony with her older orange sister entered the door to Carousel Boutique, escorted by two royal guards. The house was still coated with splashes of various batters and broken windows. The mannequins were still in a state of extreme ruin.
They made their way to the Princess that was cleaning the bathroom, who wasn't the princess at the moment. "Hello, Applejack and App-" She caught the glares of the royal guards. She sighed, and said "Howdy, big sis! Hey Spahk!" Celestias' coat was dyed yellow, and her flowing aurora mane was now red and fastened into a ponytail.
"Ah do not sound like-"
"Well anyway, Princess," Applejack cut her sister off, and grabbed the note from her, "here's a note from Spike II here!"
"Bring it to me, my loyal subjects!" Pinkie Pie canoed her way over to the farm mares on a mop bucket, dressed up in a giant, soaking wet robe. Her hair had melted taffy all over it, her coat was white with melted ice cream, and-
"Uh, Pink-er, Princess?" Applejack asked. "D'you know there's a white traffic cone glued to your forehead?"
"...yep!" Well, Pinkie would be the one to know.
"Durr, forget about the stupid traffic cone, get me a stupid new toothbrush!" Mayor Mare had her hair undyed to pink, and her coat was made pink. She was stuck repainting the walls with a toothbrush, or she was until her former one snapped and fell on the ground.
"I haveth with me," Princess Pinkie regally declared, "ein royal toothbrush!" She salvaged a filthy old toothbrush from out of the mop bucket. She then threw it at Mayor Pie, whom then cringed at the mop bucket toothbrush adhered to her forehead.
"Somepony get me a wrench!" Celestia Bloom decided to get plumbing out of the way.
"Feareth not, mine little-eth subject!" Pinkie declared. "For I haveth avec moy, ein wrench aussi!"
"I do not talk like that!" Celestia said indignantly.
"Sink!" Mayor cried, unaware of the wrench/dialect business. "I need the sink!"
"Mayor-I mean, Pinkie! Don't" Celestia cried, taking focus at her panic for the faulty sink.
"Do you-eth not wanteth mine wrench?" real Pinkie asked.
"Uh, Ah think we should go." Applejack said to her punished little sister. The little sister was all too eager to be ushered out the door.
Celestia followed the Mayor to the bathroom, ad Pinkie followed Celestia. As the Mayor turned the sink nozzle, a rusting sound came out, and then the sink and the toilet exploded with chocolate. "So this is the house I rerouted to flow chocolate through!" Pinkie observed as she, and her jail pals, and Raritys' bathroom, were swamped with chocolate.
"...shut up, Pinkie." Mayor Mare said, deadpan.
"This is going to be a long sentence." Celestia added.
