"I can't believe that we're about to go back to Canterlot." Sunset said.
"And from what I heard, Shining Armor is going to be greeting us." Twilight said.
"And that's a good thing?" Rainbow Dash asked. "You said he was the captain of the Royal Guard."
"How could you possibly know that Twi?" Applejack asked.
"Oh it's no big mystery why she knows that. Might as well tell them." Sunset said.
"Well, Shining Armor is my actual biological brother." Twilight said.
"Wait really? Your own brother is the captain of the Royal Guard?!" Rainbow Dash was stunned by this.
"Yep." Twilight said. The train arrived at the station where two unicorns were waiting. One was wearing Royal Guard armor.
"Twily, it's good to see you. Sorry that your visit won't be a social one." The royal guard said.
"Every pony, this is my brother, Shining Armor." Twilight said.
"Twilight's been writing about you all fairly well. Not just to me either." Shining Armor said.
"To Moondancer as well. Like I told you to." Sunset said.
"Couldn't forget her or the others here." Twilight said.
"Though I have to wonder what you of all ponies are doing here..." Sunset said to the other unicorn. "...Prince Blueblood."
"Prince Blueblood, here to try and flirt with me again? Or are you going to try with Sunset this time?" Twilight asked.
"Nothing like that, I assure you." Prince Blueblood said.
"I'll believe that when I see it." Twilight said, as Rarity soon approuched Blueblood.
"Been a while, Blueblood." Rarity said.
Sunset was a bit confused at that. Normally, when Blueblood isn't addressed as "Prince Blueblood" he gets all shouty and demands that the pony call him by his title. But for some reason, he's not doing that with Rarity.
"Likewise Rarity. How is Sweetie Belle doing by the way?" Prince Blueblood asked.
"Well, you know the dragon Twilight hatched for her entrance exam? He's taken a bit of shine to Sweetie Belle. The two have been on a couple of dates." Rarity said.
"Oh. Perhaps I should apologize to the young drake the next I see him. Perhaps even get ready to welcome him into the family." Blueblood said.
"Okay, some pony please explain to me how Blueblood is suddenly acting this way." Sunset said.
"Right. I guess it's the best time to tell you this: Lucky Belle is Blueblood's half brother. They share the same father, but after Blueblood's mother was lost at sea one day, Blueblood's father remarried and had a second son. That was Lucky Belle." Rarity explained.
"...Wait...so then...that means Blueblood would be..." Sunset could not finish that thought.
"Her uncle, yes." Blueblood said.
"...Sunset.mlp will stop working now..." Sunset said before fainting.
"Didn't expect to learn this today." Twilight said.
"Wait, so Sweetie Belle's Uncle Blue would be...NO BUCKING WAY!" Rainbow Dash pieced it together herself.
Suddenly Serendipity showed up. "O. M. Goodness! I totally did not see that coming. I see a lot of things coming, but this just takes the cake. It's so exciting to meet THE Uncle Blue Sweetie Belle mentions so often." Serendipity said.
"Oh, Princess Serendipity. You nearly spooked me. You should really think about calling ahead for a change." Blueblood said.
"But that's just silly. How can I surprise any mon if they know I'm coming ahead of time? Speaking of which, I've got to get busy preparing my gifts for the one I'm here to surprise. I'll totally give you a gift later, Uncle Bluey. See ya!" Serendipity said before she vanished.
"...What was that all about?" Sunset asked.
"Don't know. But aunty Celestia does want to see you soon." Blueblood said.
"What do you mean the elements have gone missing?!" Sunset exclaimed.
"I discovered it this morning. Luna's guards should've notified me if they had noticed the missing statue last night." Celestia said. "It seems Nozrog's little visit has caused Discord; a spirit of chaos; to break free from his stone prison." She added.
"Another old foe of yours? Why is this the first time I've heard of Discord?" Sunset asked.
"In my defense, Sunset, when my sister and I had imprisoned Discord in stone, we assumed it would be permanent. But I fear that in the process of finding the new bearers of the Elements of Harmony, I failed to take into account what would happen once they had new bearers." Celestia said.
"But why would Discord be able to break free on Nozrog's visit?" Twilight asked. "It just doesn't add up."
"It seems that while the seal on Discord had weakened, Nozrog's actions during his visit enabled Discord to break free from his prison in full." Celestia said.
"And he's been able to hide the elements. Of course he did that." Sunset said.
"That doesn't mean I'm not above playing a game." A male voice suddenly said. Suddenly a creature unlike anything else appeared.
"Discord..." Celestia said, teeth bared.
"Oh please, Celly, you should really learn to lighten up a bit." The new creature said.
"WOW! Two new friends in one day. It really must be my lucky day!" Serendipity said. She was suddenly on Discord's head.
"Wait, where did YOU come from?" Discord asked.
"I mean I already expected to meet you at the very least Mr. Discord, but I didn't expect to meet the infamous Uncle Blue of Sweetie Belle today as well." Serendipity said.
"What is she talking about?" Discord asked.
"Some pony we met earlier today as well." Sunset said.
"Yeah. Though you did faint when we learned about him, Sunset." Twilight said.
"Well I was not prepared for who it was." Sunset said.
"...To be fair, I didn't either." Twilight said.
"Here, would you like a present, Mr. Discord?" Serendipity asked, giving Discord a present.
"Oh how nice of you." Discord said, and when he opened the present, he was met with a pie to the face. "What the...but how did you--"
Serendipity was laughing. "I just love surprises don't you? You never know what could happen with a surprise. That's why they are surprises. I certainly already had a surprise today, meeting Uncle Blue in addition to you." She said. "Of course nothing could ever top the time when I met Pinkie Pie, see it started when--" Serendipity said before she went off on a rant.
Discord started to wilt. "...Is she normally like this?" Discord asked.
"Yeah, she can totally give me a fun time." Pinkie Pie said.
"But I digress, here, let's shake." Serendipity said, offering Discord a paw.
"Err...okay." Discord said but when he did, Serendipity's arm suddenly came off. "WAIT WHAT THE..."
Only for it to be revealed to have been a sleeve that was modled EXACTLY like Serendipity's arm. The Sylveon Princess suddenly rolling on the floor laughing. "I can't believe you fell for the old 'fake arm' trick! Gets every mon all the time!" Serendipity said.
"STOP! MAKE HER STOP! THE ELEMENTS ARE IN THAT LIBRARY IN PONYVILLE! JUST GO GRAB THEM AND TURN ME BACK TO STONE ALREADY!" Discord said.
"I dunno...I think we just found a way to keep you at bay without the elements." Sunset said with a grin.
"ACK! FINE! I'LL GO GET THEM MYSELF! AND I'LL BE GOOD! PROMISE!" Discord said before warping away.
Pinkie Pie went up to Serendipity. "You totally did that on purpose, didn't you?" The party pony asked.
"But of course I did. Because I'm me. And I wouldn't want to do any less. We should totally team up on him if he tries anything." Serendipity said.
Pinkie Pie grinned. "I like your style, Serendipity." She said.
"Well it looks like Discord got to meet some pony whose very bread and butter is chaos and it makes him look like a saint." Sunset said.
"...What just happened?" Celestia asked.
"Serendipity happened." Twilight said.
The sun princess face hooved. "Mother help us all..." Celestia said.
