Rainbow Dash wasn't the kind to worry. But one day she found herself very worried. Pinkie had promised to meet her at the chocolate shop and plan some pranks. That'd been an hour ago and Pinkie had never showed. Dash had flown up to the clouds to think.

Maybe Pinkie had a busy day at Sugarcube Corner. Dash thought to herself. Yeah, I'm sure that's it. Dash flew towards Pinkie's home and landed at the door where she knocked. Mr. Cake answered. He looked troubled.

"Hi, is Pinkie home?" She asked..

"Pinkie's not feeling too well today. She says she has a cold." Mr. Cake responded. "She doesn't look too good. I tried to get her to go to the doctor, but..."
Dash rolled her eyes. "I'll go talk some sense into her. She's probably scared of needles or something." Mr. Cake let her pass while Dash at first walked then glided up the stairs leading to Pinkie's room. She knocked on the door.

"Pinkie! It's me! I heard you're not feeling too well and I'm here to drag your fraidy-tail to the doctor!"
There was no response.

"Pinkie, c'mon! I...I'll hold your hoof if they give you a shot and I'll buy you a chocolate shake after! My treat!"
There was no response. Now Dash was worried. Pinkie never, never ever, refused a chocolate shake.

"Pinkie I'm coming in there!" Dash opened the door when she received no protest towards her statement. Pinkie was lying in bed, her mane and tail lacking their normal poofiness. Tears were running down her cheek and she was staring up at the ceiling in silence. She forced a smile when she saw Dash.

"Dashie, I'm just...not feeling too good today. Just come back tomorrow I'll be better."
"Who made you cry?" Dash demanded as she walked towards her friend, a dangerous look in her eyes. She sat by Pinkie's bed.

"No one made me cry. I'm really sick."

Dash placed a hand on Pinkie's forehead. "You don't have a fever. I mean, I don't think you have a fever. But you need to get to the doctor if you're sick."

"It's not that kind of sickness. Dash, it's a sickness of the mind. I've never told anyone."
"A...sickness of the mind?"
"Dash, I'm bipolar. You've only seen me in my manic state. This is...this is the other side of me. Not very pretty is it?"
"But something must have happened." Dash said. "Like when you thought nopony liked your parties anymore."

Pinkie winced. "Yeah. I hated you seeing me like that. That did send me towards a depressive state. But sometimes nothing happens. There is no reason this time."

"Was it something I did?"
"You're not listening Dash. You did nothing. It just happens."
Dash still didn't look like she believed the party pony.

"Alright, yesterday Twilight lectured me when we were at the library about being more quiet."
"I'll give her a piece of my mind-"

"Dash, don't. Had it been any other day it wouldn't have bothered me. She didn't know...couldn't have known. It's not her fault. It's my mind. My stupid, stupid mind. I'm a prisoner in here." She shook her head. "I'm so stupid. You're probably going to think I'm a freak and leave me."

Dash suddenly wrapped her wings around Pinkie then blushed when she realized what that meant. It was an extremely intimate act, for a pegasus to wrape their wings around another. It was an instictive gesture, practically a reflex, normally offered to distressed pegasus foals and fillies to comfort them.

Or, sometimes, a pegasus's lover. The gesture meant 'Don't fret, I am here and I will protect you. I love you.'

Do I...do I really feel that way about Pinkie? My body seems to think so. She kept her wings wrapped tight around the pink pony as she laid beside her. Pinkie snuggled into the embrace and wrapped her hooves around Dash.

"Pinkie, do you remember that time I was depressed because I lost a race that one time?"

"I remember."

"You made me cupcakes and told me jokes to cheer me up. Pinkie, anytime I've ever been sad or depressed you've been there for me." Dash told her. "This time, let me be here for you."

Dash felt Pinkie sobbing,her tears soaking Dash's main. She kept holding her.

"Thank you...thank you so much, Dash." Pinkie said. "I don't d-deserve a friend like you."
"Yeah you do. You...you make me so happy, just by being you."
"Th-thanks, that means so much you have no idea..."
She didn't stop crying for a while, telling Dash horrible thoughts she had, fears that her friends would abandon her, that she had let down her family when she'd moved away to Ponyville, fears that no one really liked her. Through it all Dash just kept her wings and hooves wrapped around her, whispered assurances to her, even sang her a lullaby. They both fell asleep, tangled up in each other. Celestia's sun rose up, gently waking Dash. She looked around at the very pink room that was definetly not hers. She stood up then remembered where she was. Pinkie Pie was nowhere to be found. She sniffed when she smelt a heavenly smell. Pinkie Pie hopped into the room. Her mane and tail were poofy again and she was carrying a plate of pancakes on her back. She placed it on the bed.

"You want some?"
Dash's eyes widened. "Chocolate syrup! Of course I want some!"

They got down to eating the pancakes, Dash relishing the sweet taste.

"Thanks for making me this, Pinkie." Dash said as she finished off the last pancakes.

"Well, you deserved something after yesterday."

"Nah." Dash said. "I was just being a good friend."
"Then I'll throw a Dash-is-an-awesome-friend-party!" Pinkie declared, bouncing up and down.

"That might make the others jealous." Dash told her.

"Yeah, you're right. Say do you still want to pull some pranks?" Pinkie asked, with her normal, excited voice.

"Absolutely!" Dash said grinning. "But, are you...okay?"
"I TOTALLY got my prescription refilled!" Pinkie announced. "Though I'm pretty sure I'm slipping into mania! HOO-RAY! LIFE IS GREAT! LET'S GO PRANK SOME PONIES! WOO!"

With that Pinkie pulled Dash from the room and then they raced down the stairs."But, seriously, Pinks-"
"I'm fine." Pinkie reassured her. "Say that thing with your wings you did...it made me feel really good. Safe."

"It's supposed to. I thought it only worked on other pegasuses though."

"I think it's because it was you that did it. You make me feel safe." Pinkie said, planting a quick kiss on her cheek.

Dash blushed. "You make me feel happy. Iloveyou."
"What was that?"
"I love you...becayse you're such a great friend. Friend."

"I love you to...friend." Pinkie said, as if she didn't know what Dash really meant. They made their way to the street and spent the rest of the day pulling pranks.

...

A/N-I have a theory about pegasus wings if anyone wants to hear it. I think pegasus wings reflect the pegasus' emotional state. When a pegasus is calm his or her wings remain by their side. If the pegasus becomes excited by something their wings may flare out. If they become angry they may automatically take to the air (even partially disabled Scootaloo exhibits this instinctive behavior). A pegasus may comfort another pegasus to whom they are especially close, a biological or adopted offspring usually, by enveloping them in their wings. Dash exhibits this behavior with Scootaloo in Sleepless in Ponyville.

Anyway I hope you liked the story. Please review.
