Pinkie slumped out of the kitchen.
"Pinkie Pie, what's wrong? Applejack and Rainbow just left without saying goodbye." Fluttershy spoke over the crowd but only just, all Pinkie Pie heard was 'Rainbow' which made her feel even worse.
"I need to be alone right now." She mumbled not even trying to hide her withered mane any longer.
"What?" Fluttershy was shocked and followed Pinkie up the stairs. "But Pinkie, every pony came here for you and this is your send off."
"Yeah well, send them all off." Pinkie said harshly with no remorse. "I'm sorry Fluttershy I need to just be alone right now, okay?" She didn't want for an answer and went to her room where the door swung shut all on its own. Fluttershy stood there at the top of the stairs looking at the closed door unsure what to do next.
"But the party..." She mumbled feebly.
Pinkie walked into her room and looked for something that she thought she would never have to use. She made sure she was quite otherwise the toothless protective alligator sleeping at the end of her bed might wake up. Finally, under her bed, she found what she was looking for. She took the small horse shoe box into her bathroom and locked the door. She lifted the lid revealing photos of Rainbow Dash and a knife. She had made this suicide kit back when Rainbow and Applejack had gotten engaged the only thing that had stopped her was Rainbow asking her to be her mare of honor. But now, there was nothing to stop her. Sure she loved Cheese, but like she had said, no where near as much as Rainbow Dash.
She wrapped her hoove around the black handle of the knife and looked at it long and hard. She decided to go through the pictures first as she heard ponies beginning to leave downstairs. There weren't that many but they all reminded Pinkie Pie in someway of how Rainbow was now Applejack's and never hers.
A picture of the pair on their wedding day.
One of Rainbow smiling with Pinkie under her arm but her attention is looking at the camera's operator: Applejack.
Pinkie just finishing a prank but Rainbow is talking to Applejack and she hadn't seen.
The last one was the most heartbreaking to Pinkie Pie: It was taken when Twilight had wanted to show them a constellation that Celestia made for her just after she had became a princess. It's Applejack and Rainbow looking down at the sunset over Sweet Apple Acres with Rainbow's head on Applejack's shoulder and Applejack's head on top of Rainbow's. Pinkie looked at that perfect photo then crumpled it into her hoove.
She was ready now.
She didn't want to live without Rainbow.
She now needed to end it all.
She raised the knife up then faced the blade towards her heart.
She felt tears escape her but her voice remained calm as she said "Goodbye Rainbow."
"WAIT!" Pinkie Pie had only a moment to react before Fluttershy came barreling in through the opened window. Fluttershy grabbed the knife from above and clasped her hooves around the slick blade. Pinkie tried to pull it out of her hooves which resulted in the knife slipping and tearing a deep gash into Fluttershy's wrist. "NAAHH!" Fluttershy gasped falling to the tiled floor.
"Damn it Fluttershy!" Pinkie Pie groaned as she saw the blood stain her friend's yellow coat. She raced out of the bathroom and retrieved the first aid kit from the kitchen. She stopped the bleeding then looked at the wound. "You'll need stitches." She muttered pulling out a needle and thread from the kit. "What were you thinking?" She asked around the needle in her mouth as she began sewing up the cut.
"What was I thinking? What were you thinking?!" Fluttershy frowned at Pinkie Pie. "What were you going to do with that knife if I hadn't stopped you?" Pinkie was silent but Fluttershy wanted an answer. "Well?"
"I was going to kill myself." Pinkie Pie said flatly.
"Why?" Fluttershy asked not missing a beat or changing her expression.
"Because I love Rainbow Dash more than live itself and I just asked her not to show up at my wedding-" But for the first time ever, Fluttershy interrupted her.
"That's right Pinkie, you're going to get married! So why on earth would you do that to Cheese, or the Cakes, or me?" Fluttershy inquired sadly, desperately.
"You don't get it Fluttershy! You don't love any pony the way I love Rainbow Dash." Pinkie retorted back. Fluttershy was quite for a long time as Pinkie sewed.
"You're right," she said finally. "I don't, but that doesn't give you the right to. Pinkie Pie, as much as you don't think it's true, every pony needs you in someway. The towns ponies need you to brighten their days, the Cakes need you to help run the bakery, the Elements of Harmony need you for your gift of laughter." Fluttershy paused then placed her good hoove on Pinkie's shoulder. "And I need you as one of my best friends." Pinkie was still focused on the task at hoove but she had began to cry which blurred her vision. Fluttershy kept her hoove where it was until Pinkie finished the last stitch and bite off the extra thread. Fluttershy then pulled her into a hug. It was something no pony had given Pinkie in a long time and slowly, her mane inflated again as grateful tears slip down her cheeks.
"Thank you." She whispered.
"You're welcome." Fluttershy smiled then she examined Pinkie's work. "Wow Pinkie, you did a really great job." The stitches were spaced out evenly and looked like a doctor had done them.
"Really? Huh, I guess I never knew that I was good at first aid." She chuckled to herself then said. "Hey, there's lots of cupcakes down stairs with our names on them. Come on!" She bounded off down the stairs like she always did when she was happy or there were cupcakes to be had.
"Be right there." Fluttershy smiled. When she was alone, she looked at the stitching again. It looked like it might leave faint scars. Good, thought Fluttershy, because I never want to forget this night; the night Pinkie Piefinally got over Rainbow Dash and began to live again. She kissed her little stitches before trotting off after Pinkie Pie who had already eaten several cupcakes.
