"I need to see that mare. NOW!" Celestia said, looking up from the piece of paper that was in her magic grasp.

"Now as in, right now?" Pinkie asked.

"What Pinkie was trying to say is, why do you want to see her?" Twilight said.

"It's very important. I saw this symbol a long time ago," Celestia nodded. "I must see her as soon as possible."

"Well, she's a superhero," Pinkie shrugged. "The only way she'll appear is if there's some big problem. But don't create a big problem just to summon her, because that would turn you into a villain."

"Pinkie!" Twilight scolded.

"I must know who she is," Celestia added.

"What?!" Pinkie gasped.

"But she's a superhero!" Rainbow Dash exclaimed.

"And her identity must remain a secret!" Spike added.

"Would ya three please quiet your comic book obsession?" Applejack said. "This is real life. Though, I admit that the mare might have some good reason for letting her identity stay a secret."

"And I have a very good reason to know her identity," Celestia responded. "This mare means something to Equestria. It could be good, but it also could be dangerous."

"Are you sure you want to do this?" Twilight asked.

"I couldn't be more sure. And I have some ponies I suspect. Do you have any?"

"Well, I don't know …"

"I'll go back to Canterlot. If you get or remember any good information, send me a letter. Please, I need to see her. Equestria's future might be at risk." Celestia opened the castle's door and stepped outside. "Good night, everypony."

"Good night," Twilight replied, before Celestia took off. Twilight didn't know why, but Celestia appeared to be flying faster than usual.

"Twilight, do you really wanna help Celestia discover Supermare's identity?" Spike asked.

"She didn't tell me exactly why she wanted to do so, but she seemed really concerned, and I trust her," Twilight replied. "But don't worry. Even if she discovers her identity, I don't think she'll tell anypony else."

"Unless Supermare turns out to be a villain trying to gain our trust!"

"How could you say that?!" Rainbow said in shock.

"Didn't you see how she saved the day ...I mean the night?" Pinkie added.

"I know I know! It's just a possible scenario," Spike mumbled. "You guys need to read more comics."

Twilight groaned.

"I'm going back to my house, and tell everypony on the way about Mare of Steel!" Rainbow Dash said, opening the castle's door.

"Me too!" Pinkie said. "Except, I'll tell them about Supermare!"

"Whatever." Rainbow chuckled.

With that, Rainbow and Pinkie exited the castle.

"I guess it's time for me to call it a night." Rarity yawned. "Goodbye everypony."

"I have a few things I need to do before I sleep," Applejack said. "Don't worry, Twilight. I trust Princess Celestia." With that, she exited the castle with Rarity.

"Oh yeah! We have a hero in real life!" Spike cheered. He then began walking to the bathroom.

"Twilight, do you suspect anypony?" Starlight asked.

Twilight sighed. "Not really. Let's just call it a night. You need to go shopping with Spike tomorrow, and I need to visit Cadance with Princess Celestia."

"I hope Cadance gets better soon."

Twilight sighed again. "Me too."

-oOo-

Luna was standing at one of Canterlot Castle's balconies, when someone dashed past her. She looked behind to find none other than her sister, Celestia.

"Celestia, you scared me for a moment!" Luna sighed in relief. "Why were you flying so fast?"

"Phew! I don't know," Celestia replied. "But it felt good, anyway."

"So, what happened? With the mare?"

"She wears a symbol I've seen before."

"What symbol?"

"I had that dream years ago, when you were...when you were still up there." Celestia glanced at the moon. "Apparently it was a vision all along."

"And what are you going to do now?"

"I must know who is that mare. I know that the symbol means something big for Equestria, but is that thing good or bad, I still don't know."

"And you want to find out if the mare is trustworthy."

"Indeed." Celestia trotted to the railing and rested her forelegs on it, staring at the sky. "She's not from this world, Luna. Her world was destroyed years ago, most likely around the time I had that vision. I will ensure that my kingdom stays safe, no matter what it takes."

"Sister, maybe you're worrying too much. Twilight said the mare…"

"Supermare, that's what they call her now."

Luna raised an eyebrow. "Well, she said that Supermare helped them."

"Perhaps I'm worrying too much. But when Equestria is in danger, I will regret that I didn't consider this."

Luna paused. "You have a point."

Celestia chuckled. "Don't worry, Luna. If I discover Supermare's identity and she turns out to be trustworthy, I won't tell anypony else."

"Even me?"

Celestia smiled. "Depends."

There was a moment of silence before Luna spoke.

"Do you suspect anypony?"

"Yes. My first suspect is somepony we're visiting tomorrow."

Luna's eyes widened. "Cadance?"

Celestia nodded.

"But sister, how? She's sick."

"Exactly. Didn't you notice how all these news about a mysterious mare 'saving the day' started to appear little after Cadance became sick?"

"You mean...she might be faking it?"

Celestia hesitated. "Maybe."

Luna shook her head. "Tia, how could you doubt your niece? I can't bring myself to think that way."

"Easy now, Luna. If Cadance is indeed Supermare, then I'll be more than happy."

"Don't you think she would've told you? You raised her, after all."

"Which is why I want to investigate her first. What problem might prevent her from telling me? I may be able to help her. Besides, she has a family now, a husband and a daughter. I'm no longer the first one she would tell about something like that."

"Yeah, you might be right." Luna took a little pause. "Now, you have to rest, sister. If what you said now was any indication, than tomorrow is going to be important."

"True enough. Take care of yourself, Luna." With that, Celestia headed to her bedroom.

Just...what was that strength I felt when I was flying? Celestia thought, as she lay in her bed. Could it be...no no, I stopped doing that ages ago. She sighed. I must sleep now, tomorrow is another day.

-oOo-

"Come in," Cadance said, after she had heard a knock on her bedroom's door.

"Hello, Cadance," Luna said as she entered the room, followed by Celestia and Shining Armor.

"Glad to see you again, my niece," Celestia beamed. "I brought you something sweet." She levitated a sachel and placed it on the stand beside Cadance's bed.

"Aw, thank you so much, aunt Tia!" Cadance said, letting out a single cough.

"How are you now?" Luna inquired.

"Much better. I think the treatment has taken its effect." Cadance smiled.

"May I ask how did you get sick?" Celestia started her investigation. "Do you remember contacting with anything unusual?"

Cadance raised an eyebrow. "Now that you mention it…"

Celestia nodded in anticipation.

"No...I don't recall anything."

Celestia closed her eyes in frustration."How often do you leave your room?"

"Tia, don't you think you're moving quickly with the questions?" Luna whispered to her sister; Celestia didn't respond.

"Well, I used to leave for the bathroom in the last few days, but now I feel better and I believe I can move more," Cadance answered.

Celestia sighed. She glanced behind her and found a closet. Something immediately caught her eye. There was a small piece of red fabric squashed between the doors of the closet.

"What's in there?" Celestia asked.

Once Cadance saw what Celestia was asking about, she opened her eyes wide. "There? Oh, well, there's...something." Cadance faked a smile.

Celestia raised her eyebrow. "What's that 'something'?"

"Tia!" Luna whispered, but to no avail.

"It's ...something you don't really need to see," Cadance replied.

"What if I need to see it?" Celestia held the closet's door with her magic.

"No! Don't open it!" Shining Armor covered his mouth.

"Why?"

"Auntie, you really don't wanna see what's in there!"

"That's not an answer." Celestia began to open the door.

"I said you don't!" Cadance raised her voice in desperation.

"Cadance, I'm your aunt. You can tell me."

"Nope. I can't"

"I may be able to help you."

Cadance widened her eyes even more and blushed lightly. "What? No! You can't help me with this!"

"What if I can?"

"Trust me, you CAN'T!"

Celestia closed her eyes and sighed.

Cadance let out a breath she had been holding.

"I'll be the one to decide." With that, Celestia swung the closet's door open.

-oOo-

"Okay, Spike, ready to go shopping?" Starlight asked.

"Ready," Spike replied.

"I wanted to go visit Cadance with Twilight, but I can't let you shop everything like you want, that would be a disaster," Starlight joked.

"I was going to say the same thing to you!"

Starlight giggled. "Okay, let's move."

As the two were walking, a flash of color zipped across the sky.

"What was that?" Starlight asked.

"That was ...Supermare!" Spike exclaimed, his eyes wide.

"Are you sure?"

"Yes. I recognized the colors of her costume. Come on, she went that way!" Spike ran in the direction Supermare had gone in.

"Wait, what about the shopping?!" Starlight galloped after Spike.

"Shopping can wait, but Supermare can't!"

Starlight groaned, but kept following Spike. "Here, we can move faster if we teleport." She held Spike with her foreleg as her horn began to glow, following Supermare's track.

They ended up in an abandoned neighborhood and hid behind a house. There were many shacks and shelters, so they presumed it was an abandoned little town.

"Spike, look." Starlight pointed towards a group of three young colts in the middle of the neighborhood. The colts were stepping back from a group of four dragons.

"I'll send a letter to Celestia, both for the dragons and Supermare." Spike began writing.

"Well, well, well, what do we have here?" one of the dragons said, as he and his friends cornered the colts.

"Didn't your mom tell you to not wander along in abandoned places?" another dragon said.

"And didn't your mother tell you to fight somepony of your own size?"

The dragons turned behind to find none other than Supermare.

One of the dragons laughed. "You mean you are my size?"

"You're right. I might be bigger," Supermare responded.

The dragon frowned, walking towards Supermare. "You think you're funny, freak?" He pushed her on the chest, but she didn't move even an inch.

Supermare sighed, before pushing the dragon, sliding him on the ground several meters backwards.

"How dare you?!" another dragon shouted, hurrying towards Super mare and swinging his claw to punch her, but she blocked his claw and punched him, sending him flying into one of the houses.

A third dragon opened his mouth and started breathing fire at Supermare. She trotted towards him and gave him an uppercut on his chin, closing his mouth and making him pass out.

Supermare turned to the fourth dragon, who was the shorter one. "Boo!" That was enough for the dragon to start flying. Supermare shook her head and held the dragon from his tail. "Come back here!"

"Mommy!" The dragon said in desperation.

-oOo-

Celestia blushed so hard, just like everyone in the room. What she had assumed was Supermare's costume turned out to be nothing more than colored gags, with a few other objects that were used for known reasons.

"I told you...don't open it," Cadance said, covering her face in embarrassment.

It's gonna be hard to stop those images from flowing into my mind! Luna thought.

Before Celestia could speak anything, a letter popped up in front of her. She levitated the letter and read it. Without saying anything, she threw the letter aside, opened the window and took off, flying as fast as she could.

"Tia! Wait!" Luna called. "I'm sorry, Cadance. I'll explain later." With that, Luna took off through the window.

Cadance and Shining sat there in silence for a few seconds.

"Well, that happened," Shining broke the silence.

-oOo-

The dragons were all tied with thin steel ropes, and Supermare was pacing before them.

"You're gonna stay here until Princess Ember arrives and gives you the suitable punishment," Supermare said, turning to the three colts. "And you, never wander in abandoned places like this alone. You never know what's lurking around."

She noticed the colts' attention was at something else.

"Hey, are you listening to me?" Supermare turned to her right, to where the colts were staring. A mare was flying in her direction, then landed a few meters away, creating a small crater where she landed.

The mare was none other than Celestia.

"Greetings, Mare of Steel."
