The two ponies returned to Canterlot. In her chamber, Luna was looking at Pinkie Pie. "What's wrong, princess?" Pinkie asked. "Did I... Did I do something bad? I am really sorry for reacting that way." Pinkie looked like a reprimanded puppy. She really didn't want to act like a spoiled brat and even though she really thought that her mother is lying to her, she didn't want to offend her that way. She didn't really think of what she is doing, because this subject meant a lot to her. Luna shook her head. "Pinkie Pie.. I know not how to tell you this," she said. Pinkie tilted her head. Luna sighed. She had no other choice. She had to tell her. "Your sister, Pinkamena Dolores Pie does not exist." Pinkie's eyes widened in shock. To think that princess would be playing with her this way... She didn't expect that. She could only imagine how would Pinkamena feel if she knew that everyone is denying her existence, just to make her sister feel better. "No... Not you too. I... I trusted you." She was slowly retreating from the princess. "Why would you say something like that?" she asked. Her eyes were filled with sadness, and it seemed like she could start crying every second. Her lower lip was shaking. "I am telling the truth. I would never lie to you," Luna said. "Pinkamena is real!" Pinkie yelled, her voice filled with despair. "Pinkie Pie, that is what Nightmare Moon wants you to think," Luna tried explaining in calm voice. "But... she visited me! You can't tell that it was a lie. I could feel her touch. You can't... It was real! " Luna shook her head. "It was not. It was Nightmare Moon's doing," she said. "Liar!" Luna just took a deep breath. She knew that Pinkie didn't really mean that. But, she had a feeling that she had to be a little bit stricter this time. Just a little. Not about the way Pinkie was addressing her. About this whole subject.
"Hypothetically... why would you want to keep believing that your imaginary sister exists? If she didn't exist, that would mean that you have no reason to be sad nor to feel guilt," she said sternly, ready for a battle of words in case it happened. "She does exist! I know, but..." Luna interrupted her. "Besides, doesn't it seem a bit unrealistic that you would just forget about her like that? Twins are usually close." Pinkie thought about Luna's words for a moment. It seemed like she realized that there was no need to argue. "I was really sad at that time. But... maybe my mum was lying after all? Just to make me feel better. We can't be certain." Luna waved her over. Pinkie reluctantly approached her. "I know a way how to find out." Luna's voice became gentle again. She carressed Pinkie's cheek. "Don't worry. No matter what the outcome is, it will be alright. Everything will be alright. I promise you that." Pinkie smiled weakly. "Thank you, your highness," her voice was barely above a whisper. Luna's lips curled into a small smile as well. "Rest a little. I have to speak with some of my subjects and then I will be back." Pinkie nodded. When the princess went outside, she lied down on a nice, soft carpet that was on the floor and curled into a ball. Her mane was still straight and it was covering one of her eyes. She was thinking about what Luna said. What did she mean when she said that everything will be alright? Pinkie couldn't possibly imagine this situation having a happy outcome.
On Luna's command, her subjects went to find the mysterious zebra named Zecora who lived in the Everfree forest. Luna needed a potion that only Zecora could provide. That way, Pinkie could be sure that she didn't interfere with the information and that she didn't create false memories with her magic nor anything like that. Now, all she had to do was wait. She opened the door of her chamber again and entered it. Pinkie looked so defenseless, curled up in a ball like a freezing little lamb. Luna lied down next to her and covered her with her wing. "Princess..." Pinkie started to get her attention. "Yes?" Pinkie managed to smile a little. "Thank you for taking care of me like this." Luna smiled as well. "What kind of princess would I be if I didn't care about those I rule?" she asked rhetorically. Pinkie nuzzled against her and closed her eyes. It felt so comfortable.
After a while, knocking could be heard. "Who is it?" Luna asked. But, it was just her guards. Once she permitted them to enter, they did so, together with Zecora. "Thank you for your help. Now, we will need to talk in private," Luna said. Two dark grey unicorns nodded and left the room with a bow of their heads. Zecora bowed down to the princess as well, until Luna said that she can get up. The zebra did so and then looked at her. "From the forest I have come, for I heard that Pinkie Pie is glum," she said. She searched her bag to find the potion she was supposed to bring them. When she found the bottle, she took it out. It was a purple potion in the transparent bottle with decorated golden neck. "This potion you both must drink, and you shall see the answer before even an eye can blink." Luna nodded. "But first, your magic to white this potion must turn, and you shall see the answer for which your heart does yearn," Zecora explained. Luna understood. She turned the potion to white with her magic. Then she levitated the bottle over to Pinkie. She could see how impatient the mare was. Pinkie took a sip and then Luna did the same. Suddenly, the room spun.
Pinkie and Luna soon found themselves on the rock farm. Rock farm that the Pie family owned. Pinkie gasped when she saw a little pink filly with sky blue eyes, working on it. "It's... It's me..." she said. The filly was quietly talking to herself as if she was talking to other person. It was painful to even watch her. She was so lonely and it could be seen in her eyes that she is feeling miserable because of that. The sound of a bell ringing soon reached their ears. "Yes, we will talk before we go to bed, when mummy, daddy and sisters are sleeping," the filly said. Then sighed sadly. "I wish I had a real twin, not just an imaginary one," she whispered and went toward the house. "The one only who would actually understand me. I... why is everyone around me... No one knows what it's like to be happy. Even... Even I don't." She was happy when her younger sisters were born. But, since then... Real Pinkie's jaw dropped. "What? It can't be. I am sure..." Luna looked at the filly and then back at Pinkie.
"Let's go inside," she suggested. No one could see them, since they weren't phisically there. Pinkie bit her lip and nodded, before doing so. Filly Pinkie and her family were gathered around the table. But, as Luna expected, there was no sign of Pinkie's "twin." Besides, little Pinkie even confirmed that she doesn't have a twin. And, that wasn't the only thing. After the dinner, Cloudy Quartz and Maud Pie went to Cloudy Quartz and Igneous Rock's room. Luna and Pinkie followed them. "What did you want to tell me?" the mother asked. Maud, who was mostly expressionless, looked worried. She took a deep breath. "It's about my sister Pinkie," she said. "Yes?" Cloudy Quartz asked and adjusted her glasses to make sure they don't fall off. "She... She is talking to herself all the time, imagining that she has a twin sister. It is normal for colts and fillies her age to have imaginary friends, but this is getting out of control. It's almost like she believes that this figment of her imagination exists. She is talking to it the whole time," Maud explained. Cloudy Quartz put a hoof over her own mouth. "How long..." Maud shrugged. "I am not sure, mother. But it lasted for definately more than a month." Cloudy Quartz took a deep breath. "Don't tell anyone. We will have to do something about that."
With a flash, Pinkie and Luna were back to their original bodies. Luna blinked a couple of times, trying to adapt to this sudden change. Pinkie's lower lip started shaking and she started crying waterfalls. Luna looked at Zecora. "Thank you for your assistance. I can take it from here," she said. With a bow, Zecora left the room, even though she was worried about Pinkie as well. But of, she knew that princess is kind and caring. It will be alright.
Luna pulled Pinkie into a hug. But, Pinkie wasn't crying because she was sad. "I honestly thought that I was such a horrible pony for forgetting my twin," she somehow got out, before she continued crying "Even though I'm kind of sad that I don't have her... I am so glad that I didn't hurt her," she said. Some things became clearer for her now. It was all Nightmare Moon's doing. The evil mare just wanted to cause harm. "I am so happy it's not true. Because, if I had a twin and if I hurt her like that... I could never, ever forgive myself. Thank you, princess. Thank you so much. Thank you for helping me and for having so much patience with me, and and... Well, for everything. I am so grateful..." As she continued blabbering, Pinkie's mane and tail became curly with just a little twitch, like they were before. And, she was happy again. So happy that words couldn't describe it. And it was all because of Luna. If she didn't have Luna, who knows what would have happened. "I am glad to help," Luna said, holding Pinkie in a hug. Pinkie soon pulled herself together as she became the same cheerful and energetic pony she used to be. That sudden change was almost unbelievable.
Soon, Pinkie moved away and smiled happily, wiping her tears off her face with her hoof. "I have to tell my friends," she said, jumping up and down excitedly, before she darted toward the door. But, she didn't go outside. Instead, she stopped and looked back at Luna, becoming shy all of a sudden. "Um... I..." Luna approached her. "Yes?" she asked. "Is there anything else you need?" Pinkie sat down. "Um..." She blushed. "I am... I am... not sure ho to say that." Luna moved even closer. "How to say what, Pinkie? You do know that you can tell me anything, right?" she encouraged her. Pinkie was breathing heavily. She was all flustered. "Well... I am not really sure if I can tell you something like that." Luna curiously tilted her head a little, but she didn't encourage her further. "Then, if you don't feel like sharing that with me right now, you can tell me later," sh said in the end. Pinkie shook her head. "No, it won't be the right time then. Give me a minute, please." Luna nodded and sat down. Pinkie took a deep breath. "The truth is that... I... I..." Her blush became darker, if that was even possible. "I love you!" she somehow made herself confess. Luna was taken aback. "R-really?" was all she could say. "I mean, I love my friends as well, but I don't love you in that kind of way. And, I don't love you just because you are a princess. I love you because of your personality. You are nice and caring and... I just love you. Even though we are both mares. I'm serious. Y-you remember that Nightmare night? At first, I was kind of scared of you and everything, but..." Who knows how long would she be blabbering again, if Luna didn't put her hoof on her mouth. "It is okay, Pinkie." She kissed her forehead. "As a princess... I am not yet sure if I can say that I love you back in that way. But... as another pony... I love you too, Pinkie Pie."
It was Pinkie's turn to be surprised. "For real?" she asked. Luna smiled. "Yes. I have loved you for a long time. Unlike me, you have a lot of energy and enthusiasm. Some might think that you talk that much. But, those are just some out of many things I love about you," she said. Pinkie was happy beyond measure. She had this on her mind for quite a while, but she never thought that Luna will love her back. Sure, Luna helped her and everything, but that didn't have to mean anything. But now... she knew. "I have a small... um... request, your highness," she said. "When we are alone, you can call me Luna. What is it?" Luna asked. "C-can I... Can I kiss you?" she asked and looked down, already imagining the princess being disgusted. They were both mares. Even though they just confessed to each other... would it be okay? Wouldn't it be too much for one day. Luna raised her head with her hoof and leaned in, until there were only a few centimeters separating their lips. Pinkie blushed again. "Close your eyes," Luna whispered. Pinkie did so. Luna moved just a bit closer and pressed her lips against Pinkie's.
