I know you have a lot of questions and they will be answered soon.

Hearing Discord's desperate calls, Fluttershy went outside to see what was going on.

"Discord?" she said, flying to his side. "What's all the commotion?"

The draconequus hid his face in his hands. "Oh Fluttershy, I have made a terrible mistake! Tammy has…"

He was cut off as something pinned him to the ground.

"Was it you?!" Pinkie demanded, steam coming out of her ears.

"What are you…?" Discord started to ask.

"My ears are steaming!"

"Huh?"

"That means my Pinkie Sense is telling me that some pony broke a Pinkie Promise!"

"Well, you're Pinkie Sense is rather late, isn't it?"

"So it was you! Apologize!"

Twilight, Applejack, Rainbow Dash, Rarity and Spike came panting.

"Finally, she stops!" Rainbow wheezed, collapsing to the ground.

"Pinkie, what's this all about?" Twilight inquired.

"Discord broke a Pinkie Promise!" the pink pony shouted.

Fluttershy turned to the draconequus. "Is this true?"

He bit his lip. "Okay, I'll admit it! I faked it! I faked not being able to send Tammy back! I could have done it at any time, but I didn't!"

The yellow pegasus gasped. "You lied to me?"

"I'm sorry, okay? I thought I was causing chaos and I started liking the human and she helped me get together with you and…"

"Wait," Rarity interrupted. "You and Fluttershy are together?!"

"Yes, yes, but that's not important right now!"

"Excuse me?" Fluttershy glared.

"I mean it is important, but Tammy found out that I lied and she got mad and ran off into the Everfree Forest!"

Every pony gasped.

"You idiot!" Rainbow cried. "Why didn't you stop her?"

"I tried, but…something happened. She demanded that I leave her alone and there was this light…it sent me flying backward."

"Really?" Twilight asked, rubbing her chin. "That's strange. I don't remember reading anything about humans having magical abilities."

"They're not supposed to. They think magic is a bunch of hooey. They don't know how to use it."

"Who cares?" Rainbow snapped. "Taffy's out in the Everfree Forest alone! We've got to find her!"

"I think it's time we report to Princess Celestia about this," Twilight suggested.

"No way!" Discord protested.

"Discord, there's a human roaming free in Equestria with no clue as to what is out there. We need all the help we can get."

"Oh, fine! Whatever! Pinkie, would you get off of me?!"

"Oops, sorry," Pinkie apologized, hopping off the draconequus.

"We'll have to split into groups," the alicorn said, leading every pony to the edge of the forest. "Rainbow and Pinkie will search left, Rarity and Applejack will go right and Discord and Fluttershy will go down the middle. After Spike and I have sent the message to Celestia, we will join you. Let's hope Tammy hasn't run into any trouble already."

Why did everyone lie to her?

"I'll be back in time for your birthday."

"We will be friends forever. Nothing will come between us."

"I'll be back with your birthday cake, honey."

"The accident wasn't your fault, sweetheart."

Lies! They were all lies! And she was a fool to believe them!

She finally stopped and collapsed on the ground and sobbed into her hands. She opened her eyes and remembered they were hooves. She looked up at the dark trees towering over her. Tammy then realized that she did not know where she was. How could she have been so stupid? She had been so intent on getting as far from Discord as possible that she had not paid attention to where she was going.

What was this place? It looked so unnatural and spooky. Did her aunts ever mention a place like this? Their stories were hardly ever scary, save one.

She had been seven years old and it was Halloween. She had invited her friends for a party at her apartment and her aunts were visiting as well. She remembered her best friend Robby frightening her with a rubber spider which he had placed on her shoulder. Aunt Molly had laughed as she prevented Tammy from killing him.

"Don't be scared of spiders, honey," she had said. "They're more afraid of you than you are of them."

"No, they're not," Tammy had argued.

"Would it make you feel better if I told you they're ticklish?"

Then Aunt Megan had gathered everyone to tell some ghost stories, but they were all tired of hearing about ghosts and asked for something different. Molly then had volunteered to tell the story and sat beside her sister.

"Do any of you kids know what a changeling is?"

No one had, but the word had horrified her mother.

"Molly, please. You'll frighten the children."

"I'm not scared, Mommy," Tammy had insisted.

The others had urged Aunt Molly to continue.

"Changelings are shape shifters. They lurk at night, searching for food."

"And they eat little kids, right?" Robby had retorted, looking towards Tammy. "Especially little girls with brown hair!"

She had stuck her tongue out at him.

"No, they're not carnivores," Molly had replied. "They feed off of something very powerful, something that humans cannot live without." She had paused for dramatic effect. "Love."

"Love?" one of the kids had said. "How can they eat love?"

"They take the form of someone you love and feed off your love for them. They drink it like a vampire drinks blood!"

"Have you ever seen a changeling, Aunt Molly?" Tammy had asked.

"Oh yes, the worst and most evil changeling of them all: Queen Chrysalis. It is she who finds food for her subjects. One day, she kidnapped me and took my form and tried to…"

Her mother had interrupted. "That's enough, Molly!"

That story had given Tammy nightmares for months, until she realized that it was just a story. However, considering how much of her aunts' stories had proved to be true so far, she wondered to what degree that one had been true.

Everything about this forest gave her the chills. She considered flying above the trees to find a way out, but she was so tired from running that she curled up into a ball. She wanted to go home. She wanted to walk on two legs again. She wished she had never come to Equestria.

"Tammy?"

She looked up as a familiar voice entered her ears.

"Tammy?" it called again.

She could not believe it. "Aunt Megan?"

She turned in the direction of the voice, seeing a figure emerge from the trees. It stepped into the light, revealing it to be exactly who she thought it was.

"Tammy, thank goodness!"

The teenager stood up. "Aunt Megan!"

Overjoyed, she rushed to her aunt and nuzzled her head against her. Megan wrapped her arms around her and gently stroked her hair.

"I missed you so much!" Tammy exclaimed. "How did you recognize me?"

"You look just like your mother, even as a pony."

Her eyes shot open in confusion. "What are you talking about?"

"You still have her brown hair and hazel eyes."

Tammy shrugged it off but then grew suspicious. "Wait. How did you even get here?"

"I came on the rainbow, of course."

She looked up at her aunt. "But I thought you said the rainbow was destroyed."

Megan's smile wavered. "I was wrong, honey. Now let's get you home. Your father is very worried about you."

Tammy blinked. "My dad's at the farm?"

"Of course, honey. He's always there for you."

Her eyes widened and she slowly backed out of the woman's embrace. Something was not right.

"So…Dad's there?"

"Yes," the woman said, attempting to hold her again.

Tammy stepped back. "And Aunt Megan?"

"Yes."

"And my cat? Fluffy?"

The woman paused. "Yes. Now come along, dear."

Tammy narrowed her eyes at her. "You're not my aunt."

"What are you talking about, sweetie? Of course, I'm your aunt."

"No, you're not."

"You've been through a lot, sweetheart. Come with me and everything will be all…"

"I don't have a cat named Fluffy."

The imposter stopped in her tracks and glared at Tammy.

"You humans are smarter than you look."

A green light enveloped her and the woman transformed into the most ghastly creature Tammy had ever seen. She was in the shape of an alicorn, but her wings were insect-like, her horn was like an antler and her legs were like Swiss cheese. Her sleek body was black and her messy blue hair was like cobwebs. On her head sat a small crown. It did not take long for Tammy to deduce who this was.

"Queen Chrysalis."

The creature smirked. "So you've heard of me."

The teenager attempted to hide her fear and stood defiantly. "You bet I have! You're the queen of the changelings!"

"And you're the offspring of that meddlesome boy and his little mare friend!"

Her horn started glowing and Tammy tried to make a run for it, but a sticky green substance was splattered on her hooves, rooting her to the ground.

"It's been a long time since a human has been in Equestria," Chrysalis mused, circling the girl.

"How did you know?" Tammy inquired.

"One of my scouts saw Discord turn you into a pony." She lifted the girl's chin. "The resemblance between you and your mother is uncanny, except you're green."

Tammy wrenched her head away. "What are you talking about? My mother never set foot in Equestria!"

The changeling threw her head back in a laugh. "I see! They didn't tell you, did they?"

"Didn't tell me what?"

"Interesting how they told you all about me but not of your mother!"

"Shut up and get me out of this!"

"Ah, yes. You are just as stubborn as your parents. Tell me, did they tell you about our little encounter thirty years ago?" Tammy said nothing. "I didn't think so. Well, my dear, the arrival of your aunts and father was an interesting development for me. They talked of a world with no magic. If we could make our way into that world, there would be nothing to stop us! So we kidnapped the youngest of the bunch and I took her form, but your progenitors weren't so easily fooled. I was this close to entering your world!

"But those meddlesome humans, and your annoying mother, found a way to stop me! And that Celestia destroyed the rainbow, the only way into your world! Now I can have my revenge on you humans as well as find food for my subjects!"

"Yeah, that's a sad story and all, but might I ask a question?"

Chrysalis groaned in annoyance. "What?"

"Why are you telling me this?"

"So that you may know why you must be destroyed."

"Wait, what?"

She shrieked as the green ooze inched up her legs.

"Once we have successfully traveled to the human world," Chrysalis explained, "you won't be of use to us anymore. That substance will encase your body completely and will suffocate you in a matter of minutes! Don't worry. I'll tell your dear old daddy what happened to you."

"You're nuts!" Tammy cried.

"If that's what you consider an insult, it's a feeble attempt. Moth! Cobweb!"

Two changelings Tammy's size appeared at their ruler's side.

"Make sure she does not escape." One of them buzzed something in her ear. "Yes, you may feed off of her. She won't last long anyway."

The lieutenants cackled and hovered beside Tammy. Chrysalis' horn glowed and she began to shrink. Soon she looked just like Tammy.

"I'll make sure your friends get a proper goodbye," she said in the girl's voice.

Tammy tried to yank herself free as her double took to the skies, cackling maliciously.

"You leave my friends and family alone!" she shouted. "You monster!"

As she squirmed, the ooze reached the end of her legs. It would only be a matter of time before it would close at the top of her head.

Yep. Chrysalis is the villain here. Well hey, why not?
