The episode begins with a yellow unicorn stallion with a bushy blue mane in a baker’s outfit walking through the path to Canterlot when a green unicorn mare with an orange mane came out from behind a tree speaking “Hey my unicorn friend, have you heard?”
“About Princess Twilight’s Coronation, who hasn’t, I’m on my way now so much baking to do and-.” The yellow unicorn said happily.
“No no, about the Earth Ponies.” The green unicorn whispered into the yellow one’s ear.
“I know their crops have been underperforming but-“ The yellow unicorn began before the green one interrupted him. “No it’s not that, they’re hoarding all the food.”
The mare then continued “I heard the mayor of Appleloosa say that if unicorns want to eat, they can use their own hooves food to dig.”
“How awful.” The yellow stallion said angrily.
“We unicorns need to stick together especially since the Pegasi are causing strife as well.” The green unicorn mare said solemnly making the yellow unicorn stallion nod before walking off to Canterlot.
Soon the green unicorn began chuckling evilly as she saw the baker snub Mrs. Cake.
We then see the green unicorn at Grogar’s cave with Cozy Glow washing yellow paint of her in the water while Tirek was sitting at the rock table.
“Ah, Chrysalis another successful field trip I presume.” Tirek smirked.
“Turning the Earth Ponies and Unicorns against each other was almost too easy.” Chrysalis nodded.
“I did my job freaking out the Pegasi, but now I need to wash this disguise off.” Cozy Glow informed her partners.
“Excellent work minions.” Grogar smirked as he walked over to the Legion Of Doom. Chrysalis silently snarled at being called a minion but knew Grogar would punish her for defiance so she shut up.
“We could take down Twilight and her friends a hundred times but as long as they still have the love of friendship by their side, they’ll never quit.” Grogar said “Soon we will attack Equestria and you will all have your own lands but to succeed we must work together.”
“Of course I think we figured that out already.” Chrysalis smirked.
“Don’t tempt me Chrysalis.” Grogar seethed before regaining his malicious smirk “It is now time to give each of you three a fraction of my power.”
Soon Grogar readied his horns and his bell was activated, Cozy Glow, Tirek, and Chrysalis got gleams in their eyes as the bell blasted them but something was different about them.
Tirek was now in his third form. Chrysalis’ crown glowed a light green, Cozy Glow now had bigger wings and an alicorn horn.
Soon all four villains began laughing maniacally.
Soon we see the inside of the Canterlot Castle where Twilight, Spike, Celestia, and Luna were.
Twilight was currently sitting on her new throne, while Spike was using a ruler on her head to make sure if the crown would fit on her or not while Celestia and Luna were watching.
“Oh sister this is a very special day.” Luna said happily.
“Yes Twilight is all grown up.” Celestia said with tears of joy.
“Should we tell her that we cleared out our Royal Suite so she and Spike could move in?” Luna asked.
“Oh let’s not do that yet, Twilight doesn’t need anything else to worry about.” Celestia told Luna.
We soon see Spike finishing with measuring Twilight’s head.
“You worried?” Spike asked, concerned.
“About what?” Twilight asked, smiling.
“Well for one about leaving Ponyville and our friends?” Spike said “I’m really gonna miss them Twilight, aren’t you?”
“Of course I’ll miss them Spike but I can always visit them anytime.” Twilight said.
“Okay but are you worried about ruling Equestria with your friends’ help?” Spike asked.
“Actually I feel pretty good, We've all faced so much and come out okay. I know we're up to the challenge of keeping Equestria safe and happy. There's nothing we can't handle together. Which reminds me...” Twilight said happily before using her horn to levitate a red box to Spike. Spike then opened it to reveal a golden necklace “Royal Advisor, what’s that?”
“A new position I created for you. You've been at my side for every step of this journey. Knowing I had you to count on gave me the strength I needed to grow and succeed. I wouldn't be here without you.” Twilight said smiling at Spike who teared up with tears of joy before hugging Twilight.
“Thanks Twilight, I’ll always be your right hoof dragon.” Spike wipes away his tears with a smile.
“You’re welcome Spike, we should probably get done these errands though.” Twilight said levitating a list over to Spike.
We then see that Canterlot looks empty while Fluttershy and Rarity were walking on the road.
“That’s odd, the streets seem very empty today.” Rarity raises an eyebrow.
“Yes it does seem a bit strange.” Fluttershy nodded.
Rarity immediately brightened up when she saw Twilight and Spike flying over to them “Ooh! Twilight, darling! You're just in time. Only one more pre-coronation stop. We're picking up the final touch for your apres-hors d'oevres gown...
“Is that before or after the royal marshmallow-eating-contest gown?” Twilight joked.
“What?! I haven't made one of those! You must tell me when they add these sorts of things!” Rarity began to panic before writing something down on a scroll with a quill.
Twilight then lowers the scroll before speaking “Whoa Rarity relax I was just joking.”
“Joking on the day of the Coronation, you’ve come a long way.” Spike smirked from mid-air making Twilight giggle.
Soon the three ponies and the dragon made it to the thread shop when Rarity tried to open the door with her magic.
“Well that’s odd, they seem open.” Rarity said before tugging on the door.
Soon we see Lemon Drops from the door window “What do you want?”
“Oh. Well, this being a thread shop, I thought I might buy a yellow thread?” Rarity smiles nervously.
“Put the bits in the mail slot.” Lemon Hearts glared at the four visitors outside.
Rarity soon took the boys out of her saddlebags and put them in the mail slot like Lemon Hearts asked before Lemon Hearts levitated the yellow roll of thread.
“What was that about?” Twilight asked, raising an eyebrow.
“You know designers. Don't like being interrupted when they're on a creative roll. With thread this exquisite, can you blame them?” Rarity reassures Twilight with a smile.
“Weather for the coronation is sunny skies!” Rainbow Dash said, moving one last cloud before flying down to Twilight, Spike, Fluttershy, and Pinkie Pie “It was weird, though. Not many Pegasi wanted to help me clear the clouds. They were kinda on edge.”
We then see a grey unicorn keeping a watchful eye out before he runs fearfully into his house which the group saw.
“They’re not the only ones.” Spike said solemnly.
“It's the first shift in royal power in over a millenium. Of course everypony is a little jumpy. Change does that.” Rarity said.
Twilight lowered her head at this before Fluttershy picked it back up with her hoof “But I'm sure it's not because they're worried about you.” She said comfortingly.
“How could they be? How many times have you saved their flanks by now?” Rainbow Dash asked smugly.
“You're right. I'll just have to let everypony know that even with Celestia and Luna gone, we'll make sure things stay the same.” Twilight said happily.
Soon we see Applejack hauling apples from the back of a cart with a black unicorn guard glaring at her, making her uncomfortable.
“Twilight! There you are!” Applejack said happily while walking over to her friend “You mind tellin' your friend here that I don't need an official guard wherever I go? Especially if he ain't gonna help carry apples?”
“I appreciate you taking such good care of my friends, but we're fine now.” Twilight smiled at the guard.
“It was the strangest thing. He kept callin' me ‘ Earth Pony’ like I didn't have a name. And watchin' me like he thought I'd steal the silver!” Applejack said suspiciously.
Soon the kitchen door opened with Pinkie Pie running out with cupcakes all over her.
“Do not go in that kitchen!” Pinkie Pie warned her friends “For some reason, the bakers are super grouchy with each other. That unicorn chef started throwing dessert at Mrs. Cake! I tried to help, but I got caught in the crossfire!“
“You sure this is just pre-coronation nerves?” Twilight asked nervously.
Soon Discord teleports in with a worried frown “It’s worse than pre-coronation nerves, apparently the Earth Ponies, Pegasi, and Unicorns have turned against each other, the Unicorns are accused of being too snobbish, the Pegasi are accused of not stopping storms sooner, and Earth Ponies are accused of hoarding food.”
“And you’re just telling us this now.” Rainbow Dash said, annoyed.
“This has only been happening recently so don’t blame me.” Discord said.
“If Discord’s right, we need to do something about this.” Fluttershy said fearfully.
“But the coronation is about to start soon.” Rarity said.
“Look I’ll clarify that these rumors are not true at the ceremony and I’ll alert Celestia and Luna so we can do something about this.” Twilight explained.
We then see Celestia and Luna walking down the castle halls when Luna begins shuddering “I feel a sense of impending doom.”
“For some reason so do I Luna.” Celestia said fearfully before both of their eyes glowed white and they began to have a vision.
“It is time to discuss a plan on how to take down Twilight and her friends.” Grogar smirked to Tirek, Cozy Glow, and Chrysalis.
Celestia and Luna’s eyes returned to normal and Celestia began speaking “Did you just have a vision of Grogar?”
“I did he was also with Tirek, Chrysalis, and Cozy Glow.” Luna nodded.
“We must warn Twilight and her friends immediately.” Celestia said fearfully.
Soon we see the Mane 6, Spike, and Discord outside the castle when Spike burped out a letter.
“It’s from Princess Celestia and there’s an emergency.” Spike widened his eyes.
“Let’s run.” Rainbow Dash began running before Discord rolled his eyes and snapped his fingers which sent him and the others to the throne room making Rainbow Dash run into the stairs.
“Will you warn me before you do that?” Rainbow Dash asked, annoyed.
Discord smirked before Celestia began speaking.
“Thank you all for coming, we have urgent news.” Celestia said in a worried tone.
“Tirek, Chrysalis, and Cozy Glow have teamed up along with Grogar to take over Equestria.” Luna explained.
“What?!” The Mane 6 cried out in shock.
“Wait isn’t Grogar an old pony’s tale?” Spike asked.
“Oh but he is all too real Spike. And he is about to show up to Canterlot along with our past enemies.” Luna said.
“Twilight, Luna, we need to make a plan. Maybe it's not too late to stop this disaster from happening!” Celestia instructed her fellow princesses.
Twilight nodded firmly before speaking to Spike “Spike! Send a letter to Star Swirl! Tell him we need the Pillars to guard the border of Canterlot!”
Twilight’s voice was heard as Starswirl got his letter “If the villains are coming for a fight, we'll have one waiting for them! With Chrysalis on the loose, she'll go after Starlight She needs to evacuate the school, and go into hiding!”
Starlight and Trixie were seen receiving a letter at Starlight’s office and gasped in shock
“Warn Cadence and Shining Armor they’re our final line of defense if we fail!”
Cadence and Shining Armor are seen reading the note in their throne room.
“The ultimate battle for the fate of Equestria is coming!” Twilight said with a determined frown.
