Shortly after Rainbow's strange dream, she had gone to Twilight's home, Golden Oaks library. She had hoped that this would solve the problem of her dreams, as she believed Twilight would be able to help her find out why she had had this dream in the first place. Twilight only replied with a few short, in Twilight's eyes anyway, words.
"I'm not really sure, Pinkie or Rarity might be able to help you with this. I suggest Rarity be the first one to visit, as she's the one to talk to about these matters." Twilight continued talking for a good five minutes before realizing that Rainbow had already started on her way to Carousel Boutique, Rarity's home and business.
By the time that Twilight had noticed Rainbow's leave of her, Rainbow had already gotten halfway to Rarity's boutique. Though not flying as she normally would, she had been trotting faster than an average pony would, her head down as she was deep in thought. Rainbow looks up and to the left in time to see Applejack selling apples in the market area of Ponyville, she smiles as best she could and continues trotting toward the boutique. As she arrives at her destination she nearly trots into the door, shaking her head and regaining her focus, she knocks quietly on the door.
"Just a moment dear, in the zone!" Rarity speaks the moment a sound is heard at the door, in her voice was a sophistication that resided in only her, the only pony in Ponyville who lived and breathed fashion.
Rainbow begins to pace back in forth in front of the door for a moment before she sees Rarity at the door, waiting for her. Turning quickly toward her she dashes inside of the boutique and pulls Rarity in, causing Rarity to yelp in surprise as sash closes the door and locks it. "Help me!"
For a few seconds after Rainbow had spoken she receives a blank stare, a confused Rarity being the one in a confusion at this point. "Rainbow darling, whatever do you need my help for? Surely you're not looking for a dre-"
Dash cuts her off as she speaks, trying to explain a dream she didn't quite understand. "Earlier in the park, when I fell asleep-"
'Shocking...' Rarity whispers in an exaggerated tone.
"-I had a dream where I found Princess Luna singing..."
"This isn't much to go on dear, please explain this "dream" of yours, in more detail?" Rarity asks, now curious as to what this dream really was and why Rainbow seemed so bothered by it. She never seemed bothered by the dreams she had, what was so different about this dream?
Rainbow nodded slowly, a slight blush appearing on her face again as she thought of the dream. "I flew toward Canterlot to get away from the constant begging for me to relax. I kept going faster and faster until the moon started to come out, it enticed me to the point where I unintentionally started to relax my muscles as I slowed down to a lower than average flight speed."
Rarity smiles as she continues, another thing sparking curiosity, Rainbow was beginning to sound like Twilight in her explanation.
The cyan pegasus chuckles nervously before continuing her explanation, "It didn't seem odd until I heard singing... Beautiful, enchanting singing coming from the Canterlot Gardens... As I got closer to the gardens I realized that it was the Princess, Luna... I listened for another moment before I took a step forward and said her name, she looked at me and asked what I was doing there. After a moment of waiting for a response she smiled and walked toward me, she put her hoof on my cheek and... she... she k-kissed me..."
Rarity continues to smile throughout the explanation until the last part, which caused her jaw to drop slightly, "Darling, it seems to me, from what I've heard, that you've begone to fall in love with Princess Luna. Have you, ever received any other idea of this thought?"
Rainbow blinks a few times after Rarity finishes talking and shakes her head, "This- This is the first time it's happened... L-love...? Me? Rainbow Dash, fastest flier in Equestria, and most awesome pegasi, has fallen in love... with a princess!?" Rainbow turns toward the door and opens it, running out and slamming it closed again, leaving Rarity in a slight daze.
"Well, I only told her that she may be in love. Isn't that a grand thing?" Rarity turns toward the dress she had been working on and continues to stitch the lace design into one of the seems.
"Love? No, not me! I'm not in love, I can't be! It's not possible!"
Rainbow Dash jumps and falls onto her plot as Pinkie Pie pops out of a bush and gasps loudly, "You're in love? Why didn't you tell me!?" Pinkie Pie yells excitedly, hugging her close friend very tightly with her trademark smile on her face. "Who is it? Is it one of our friends?" She gasps loudly again, realizing what she thought was the truth, "It's Fluttershy!"
Rainbow Dash gasped for air as her friend held her tightly, too tightly for her to breathe at the moment. She finally got her hoof up to push Pinkie off a little, getting enough room to speak, "I'm not in love! At least... I think I'm not... And it's nothing to do with our friends, Fluttershy included..."
"It was a dream then? And no matter what you say or do, you can't convince yourself that this dream wasn't just a random occurrence with no bearing on your feelings toward this pony in particular?"
Rainbow stared at Pinkie for a moment, unable to understand how she could know. "H-how did you know...?"
Pinkie just smiles and slowly walks in the direction that Rainbow was going, toward SugarCube Corner, talking quietly in a rare calm tone. "Come on Dash, I'll show you."
Rainbow gets up and follows behind Pinkie, admiring the pink pony for understanding her feelings and for having a rare moment of calmness with a very hyper friend. After a few minutes of silent walking on the oddly empty streets of Ponyville, they arrived at SugarCube Corner, heading in without a word to the other.
"In my room, I have a way of knowing the feelings that you have, in my own way."
Rainbow follows her inside and quietly closes the door, quietly walking through the building as not to cause any distraction to the Cakes as they work in the kitchen. She follows her friend as she goes up the stairs, yawning from a lack of sleep.
Pinkie turns toward Rainbow and giggles, stopping before opening her door. "What you see in here, is a secret. Pinkie promise you won't tell anyone?"
She sighs as she begins to speak, mimicking the movements of the "pinkie promise" with her hoof, "Cross my heart and hope to fly, stick a cupcake in my eye." She smiles slightly after finishing the statement, always having loved the creativity of her pink friend. As she finishes saying it Pinkie smiles and opens the door, stepping inside. She follows her friend yet again and looks around the room, what she sees in the back corner of Pinkie's room, causes Rainbow's eyes to widen, unsure of how to think. "H-how long... have you been drawing these and... taking these pictures...?" She blushes slightly, unwilling to ask what it was she was seeing.
