Rainbow Dash streaked through the night sky, trying to get as far away from the castle as she could. 
'I can't believe I actually kissed him!  And I actually kinda... enjoyed it.  Ah!  What is happening to me?!  I'm not supposed to be feeling all sappy and stuff, I'm supposed to hate it!  Then how come I feel like kissing him again?!'
"Rainbow, wait!" Soarin huffed as he flew to catch up with her.
Rainbow's eyes widened in surprise. 
'He followed me!'
She flew faster, trying to shake him off her trail.  Soarin caught up quickly though, and tackled her onto a cloud.
"Rainbow, are you okay?" Soarin asked worriedly.
He began to see tears form in the mare's eyes as she squirmed beneath him, and his eyes widened. 
'Is the Rainbow Dash really crying in front of me right now'?'
"Get off of me!" Rainbow Dash yelled as she shoved Soarin off of her.
She fluttered over to a corner of the cloud to sulk, turning the section dark.  Soarin was surprised, he'd never seen the vulnerable side of Rainbow Dash before.  He cautiously fluttered over to her and sat down.
"Rainbow, are you okay?" he said softly.
Rainbow tried to blink back her tears, but failed to and buried her face into Soarin's furry chest instead.  Soarin's face lit up on fire as she kept sobbing into his chest.  He slowly wrapped his wings around Rainbow's small frame, enveloping her in his embrace.  He didn't exactly know what he was doing.  It just felt... right.  Soarin didn't care that his fur was soaking wet either, he would do anything for her, he knew that now.  Rainbow's sobs turned into hiccups, which lessened to sniffles.  She just felt so safe in Soarin's embrace, as if nothing could ever hurt her.

Not mine, got it from deviantART.

"Rainbow, are you ready to tell me what's wrong?" Soarin asked gently, still hugging her tightly.
"I-I think so." she sniffled. "I guess I'm just confused.  Before you came along, I didn't care for any sappy stuff cause I thought it wasn't cool, so when I kissed you and actually... enjoyed it, I just didn't know what to do.  I also am... maybe a little afraid of trying a relationship.  I-I'm afraid that maybe you don't like me, or that you'll leave me like Tank does in the winter, or-mph!" Rainbow was silenced by Soarin kissing her passionately.  Her wings shot up in surprise as she blushed beet red, before kissing him back just as fireworks erupted all around them.  At long last, Soarin broke the kiss, both gasping for air.  Soarin flicked away her remaining tears with his wing tips, and raised her chin so their eyes met, magenta staring into emerald.
"Rainbow Dash I will never, ever leave you.  You mean the world to me, and I'm sorry for all the times that it seemed like I didn't care.  Being in a relationship isn't uncool, it actually can be pretty awesome." Soarin reassured her.  "I guess what I'm trying to say is... Rainbow Dash, will you be my marefriend?" he asked with hopeful eyes.
Rainbow was quiet at first, but suddenly an ecstatic grin appeared on her face.
"Would I?! Woohooo!!!!!" she yelled happily as she flew straight into the air and began to do her victory dance.
Soarin watched her from below, admiring the beautiful and athletic mare who had just become his marefriend rejoice.
"Uh... Dashie?" Soarin called, bringing her back to Equestria.
Rainbow's face turned into one of embarrassment as she blushes slightly.
"Heh heh, I mean, I would love to be your marefriend." Rainbow said as she landed softly on the cloud again.
"We should probably head back.  Your friends must be worried sick about you!" Soarin said.
"Yeah.  Uh, Soarin?  Are we going to tell everypony that we're...ya know, a couple now?" Rainbow Dash asked, turning pink.
"Nah, we'll just let them figure it out on their own," Soarin said, as he casually draped a wing around Dash, pulling her closer to him.  Rainbow reddened at his touch.
"Okay then, let's go!" she said as the couple flew toward the castle.

The two pegasi landed on quietly on the balcony, the party still raging inside.  Just as Rainbow Dash placed a hoof onto the floor, a pink blur tackled her to the ground.
"DASHIE!  YOU'RE BACK!!! ARE YOU OKAY?!?!!!  HOW COME YOU LEFT US!!!!" Pinkie Pie shouted, Rainbow wincing with every word.
"Pinkie!" Twilight scolded as she yanked the earth pony off of Rainbow with her magic.
"Thanks Twi," Rainbow said, as Soarin helped her up.
"So why did you leave us?" Pinkie asked impatiently.
"I was dealing with some... emotions and needed to be alone.  Soarin helped me out though, and everything's fine now," Rainbow Dash explained, blushing slightly.
"What kinda emotions?" asked Applejack skeptically.
"The special kind," Soarin said as he pulled Rainbow closer to him with his wing.
Rainbow blushed furiously, but nodded in agreement.
Her friends gasped around her, and a high pitch squeal in delight was heard.
"So you two an item now?  Why, this is simply marvelous!  Ooh!  Rainbow, darling, I am so very happy for you!" Rarity squealed.  "And to think that Rainbow Dash here got a coltfriend before any of us.  Who would've thought of that?"
"Hey!  I'm pretty sure you gals will find your special someponies soon too." Rainbow Dash reassured them.
"Weeee!!!!!  This is sooooo awesome!!!  Do you know how long I've been shipping you two?!  Now I can finally throw that "Congrats you're a Couple!" party I've been planning for you guys since the Young Fliers Competition!" Pinkie shrieked as she threw confetti into the air.
"You've been planning that since then!" Rainbow Dash said in disbelief.
'Well, duh!  It was sooo obvious you guys were going to get together!" Pinkie said.
Soarin smiled as he watched his new marefriend talk to her friends, when he spotted a reluctant Fleetfoot thrust a hooful of bits to a smug Spitfire in a corner.  Soarin raised an eyebrow, and trotted over to them.
"What are you guys doing?" he asked.
"We bet on you asking Dash out.  I thought you were too chicken to, but Spit thought you were going to, so she won the bet," Fleetfoot said
sourly.  "I'm happy for you though, Soar!"
"You guys bet on me asking out Dashie- er, I mean, Dash?!" Soarin said, flustered.
"Yeah, it was so obvious that you and Dashie were going to happen.  Heck, I made 50 bits off of you guys!" Spitfire said triumphantly.
"Aww you gave each other pet names, that's soooo cuuuuteee..." Fleetfoot teased.
'Way to go, Soarin.  Just keep adding more fuel to the fire.'
"Hey, at least it sounds better that just Fleet or Spit.  Now if you'll excuse me, I'm going to go join my marefriend," Soarin said before returning to Rainbow's side again.
"Hey Soarin, do you wanna come over to my house and spend the rest of Hearth's Warming together?" Rainbow Dash asked nervously.
"I'd love to Dashie," Soarin said with a smile.
"Hey girls sorry, but Soarin and I need to get home." Rainbow Dash said to her friends.
"Oh no problem at all, darling!  I hope you two have fun!" Rarity said.
"See you guys tomorrow!  Happy Hearth's Warming!"  Rainbow said goodbye as she and Soarin left Canterlot and flew towards Ponyville back to her house.
