Sorry this took so long! This is the best chapter in my opinion!
Peacock awakened in a dark and musty room. Her head was pounding as she slowly opened her eyes to see a swarm of changelings guarding her. She jumped up, "What's going on? Where am I?! Who are you ponies?!"
"You best be quiet if you know what's best for you!" One of the nearby changelings snarled at her.
"What do you mean by that?" Peacock questioned.
The Queen stepped forward, her shadow looming threateningly over the mare, "Trust me, you'd rather not know."
Peacock's eyes grew wide, then narrowed to a dark glare, "Chrysalis! Why have you taken me here? What's going on?!"
Chrysalis glared back at her, clearly getting annoyed, "When will you learn to be QUIET?! Or you will face serious concequences otherwise."
"I can't be quiet! It's in my nature. I can just talk for hours and hours and hours... maybe even days! You know, this place is very dark and gray. You should add some colors. The holes need to be fixed too! Don't you get drafts in here? Another thing, what do you eat? Oh! Oh! How about-"
"Would you please just SHUT UP" Chrysalis screamed, "I do not have time for your petty chatter! There are much more important things to discuss!"
"How about you shut up? I was trying to finish my story!" Peacock said, annoyed.
Chrysalis glared back at her darkly and leaned closer to the yellow mare, "Do. Not. Test. Me. Or I will show you what we here at the hive do for food."
At this, the swarm of changelings around her chittered and laughed as Peacock's face turned to terror. She stepped up to the Queen... and smacked her in the face! The other changelings gasped in horror. "You just got smacked!" Peacock said.
Finally losing her temper, Chrysalis reared and blasted Peacock with magic, sending her backwards onto the floor.
"How DARE you disrespect me! I will not allow this kind of nonsense to continue! Guards! Take her to a cell in the lower hive immediately! Get her out of my sight at once!"
"Yes, my Queen!" Three changelings grab her as she struggles to get free.
"Waaaaait! Before you send me, I'm going to need some things!" Peacock screamed.
Chrysalis squinted at Peacock, detesting the idea. Rolling her eyes, she mentally weighed her options. "Fine. But only if it keeps you quiet and out of my sight."
Peacock took a deep breath, "I need my computer, my charger, my bed, food, water, my phone, my sister and mom, my dog, my tv, fridge, and plant pot! I need my PonyStation and controller, books, my house, a desk, plushies, pajamas and clothes, Pony Cena for a wrestling match, my helicopter, chainsaw... Oh! Let's not forget my tiara!"
The look on Chrysalis's face was one of pure fury and rage, "Would you please just shut your mouth?! Get her... whatever of those things we have! Now leave before you regret it!"
"I regret nothing!" Peacock screamed while being dragged away by the changeling guards.
Chrysalis slumped on her throne, sighing, "How annoying can a pony be? How do ponies put up with her?!"
"Maybe they just think they can?" Abelle questioned.
"Honestly Abelle, I don't care. Who asked you to speak, anyway?"
"Sorry, My Queen..." muttered Abelle.
Suddenly, a changeling zoomed into the throne room at top speed, "My Queen! I am so sorry to intrude! But you must know... Heartsy has returned."
Chrysalis's eyes widened and her mouth curved into a cruel smile. "Excellent! Bring her to me at once!"
"Yes, my Queen!" The same changeling replied, buzzing back out of a hole in the hive.
"The time is nigh, my little changelings. I want all of you to clear the room now! I wish to speak with Heartsy...alone."
The remainder of the drones buzzed here and there, leaving the room upon the first command. They had a feeling that whatever was about to come wouldn't be pretty.
Morning in Ponyville glistened brightly as Princess Celestia raised the sun once again. Ponies bustled here and there, some rising earlier than others to get to work or school on time. A group of ponies gathered inside Sugarcube Corner.
"Where in Equestria could Peacock be? We've been waiting for a long time!" PK said, casually eating a donut.
"She's usually here by now! Oh I hope she's alright..." Starfire said with worry.
"Oh, haven't you ponies heard?" Pinkie Pie said, bouncing over with more breakfast items, "She and her family disappeared last night!"
"How could you possibly know that? Everypony was asleep!" Rose said in shock as Pinkie shrugged it off. "Everypony's been talking about it! Especially since she left without telling us! Ooo! Do you think maybe she went to a big party?!"
Sky shook his head, "Nah, she usually hides under tables at parties."
"Or has fruit on her head like last night!" Cuddlebuttons laughed, trying to lighten the mood. While a few ponies giggled along, they still felt a sense of dread. First Heartsy goes missing after her identity was revealed, and now Peacock was missing! Something just didn't add up.
Professor Haystacks trotted though the door of Sugarcube Corner, the bell jingling merrily, in stark contrast to the mood.
"Hey there Professor! Do you have any news?" Shaky said quickly, still worried about his friends.
"Indeed I do," said the Professor, "Though I'm afraid I suspect that it's not very good. Mysterious ponies were spotted hanging around Peacock's house yesterday soon before her family disappeared. I suspect that they were changelings."
"Well what's wrong with that?" Shutterbug questioned.
"Well, since Peacock and her family are now missing, I'd suspect the changelings were the ones who pony-napped them. As for Heartsy, as I'm guessing none of you have seen her, nopony has seen her since she ran off last night. Either she's hiding really well, or she's gotten pretty far away. I wonder if the two are connected..." Haystacks said. He stared up into the sky pensively as he finished.
"But Heartsy would never do that! Would she?" Paige said.
"She did seem different from the other changelings..." Cuddlebuttons thought out loud, "Could she just have been pretending?"
"No!" Sky said suddenly as everypony stopped to look at the stallion, "I don't think she was faking. You can't fake a friendship like that."
"I'm inclined to agree," Haystacks said, "There was another changeling watching her last night, and you don't keep tabs on one of your own unless you're suspicious of them."
"What really?" Flux said in surprise. The others looked varying degrees of surprised as well. Haystacks took a second to notice, but he eventually caught the mood.
"What? It wasn't really relevant before now," Haystacks said.
"Well, all the more reason," Flux said, "I'll bet that other changeling got to her!"
"Well then it's decided. We should go the hive to see if Heartsy and Peacock are there!" Shaky said daringly, surprising even himself at his boldness.
Rose smiled at the dragon but voiced her own concern, "I agree, but does anypony know where the hive even is?"
"Of that, I'm not certain. Nopony has ever found it before, at least not that they've admittedly publicly. The general direction is known, but the whole region is officially off-limits, I suppose if somepony flew up high enough, they could spot it... depending on how much of it is above ground, of course..." Haystacks said slowly, mostly to himself. He looked around, but was met mostly with shrugs.
"Don't worry about that. I have an idea." Sky said with a smile.
Queen Chrysalis sat upon her lofty throne, thinking of how absolutely brilliant she was. Everything was going perfectly according to her plan this time and she was not about to let anything be ruined. She heard hoofsteps approaching and straightened herself to look even more impressive.
Four changelings entered the throne room, holding a struggling Heartsy. She did not look up at the Queen, feeling utterly defeated. Too exhausted to fight, she braced herself for whatever form of punishment she would face.
Queen Chrysalis smiled at this, despicably loving every moment of it. "That will be all my drones. You may leave."
"Yes, my Queen!" They dropped Heartsy on the floor without a care and left through a hole in the ceiling.
Heartsy still could not bring herself to face the Queen and flinched as Chrysalis started speaking, her cold voice echoing through the now nearly-empty room. "Well, well, well. Look who finally decided to come back. And at what cost?"
The reminder of her friends made Heartsy's complacency melt away and burn into hot anger. "My friends. Or at least who I thought were my friends, she said with a grimace.
Chrysalis sighs, "Finally. After all this time, you have finally seen things my way. Friendship consists of nothing but lies. You don't need those pathetic ponies in your life. All you need is yourself."
"That's not true!" yelled Heartsy, "I know they said some pretty harsh words... but maybe things can be made right somehow."
The Queen gave a short barking laugh, "Oh you fool! You cannot make things right! You are a changeling! Ponies would never trust a changeling to be their friend. And rightfully so. Especially what you did to... one of them."
Heartsy now looked confused, "What do you mean? I never drained any of their love, though I did come close at times."
A cruel smile etched the lips of the Queen once more, "Are you sure about that?"
DUH DUH DUH!
