Rainbow Dash bawled against Twilight's coat in the train.

"We were going to get married!! We were going to have a family..."

She sobbed, and pulled herself off of Twilight, stalking off towards the library.

"Twilight, where's your quill? And where's your paper?"

Twilight was flustered.

"Why?"

"I'm writing a letter to Celestia."

"Uh...I'm not sure you should..."

"Why in the hay not!?"

"Because, sugarcube, yer' all worked up!"

Rainbow Dash gaped at Applejack in surprise.

"You don't say!! My husband-to-be, and the father of my foal, just died because Celestia did nothing!"

"No, Rainbow Dash! I won't let you near my quill and parchment until you calm down!"

"Calm down!? How dare you!? Put me down, Twilight! Put me the buck down!!"

Twilight winced in emotional tumult, her magical aura surrounding Rainbow Dash.

"Twilight."

She nodded, concentrating on the magical hold. Fluttershy continued to talk, raising her voice slightly to drown out Pinkie Pie's insanely loud sobbing, and Rainbow Dash's shouting.

"Let her go..."

Twilight did. Not because she wanted to, but because she just couldn't do it anymore. Her emotions were bubbling over too much, and so were her tears.

Tears for Peter, that a friend of hers had died.

And tears for herself, because Celestia had abandoned her.

"Go ahead...but...let me write something in the post script..."

"Yeah, whatever."

Rainbow Dash immediately picked up the magically supplied quill, and wrote on the magically levitated paper.

After a few moments, consisting mainly of sobs and occasional scratching noises, as well as small curses here and there, the paper was passed over to Twilight, which read as such:

Dear Princess Celestia,

Buck you.

I'm at a loss for words.

You let him die.

My husband.

My foal's father.

After I fought Nightmare Moon and Discord for you...

This is how you repay me?

Buck you,

Rainbow Dash.

Twilight gulped, and added her own small post-script.

P.S. I refute you as my mentor. -Twilight Sparkle

She walked over to the membrane, behind which Spike and Rarity remained oblivious.

Spike stood, and grasped the scroll.

"What happened?"

"Peter's dead..."

Spike blinked. Twilight sobbed. Rainbow Dash roared in agony and rage. Applejack shook her head in disappointment, holding her hat to her chest with a hoof. Pinkie Pie cried even louder. Fluttershy closed her eyes.

And Peter stood, unseen, and unheard by anypony as he gently retracted the membrane covering his compartment in the train, shaking his head, amazed that the flu had actually left his body...

Peter winced as he heard Rainbow Dash scream at Celestia, for letting him die.

Oh, geez...I guess I really was dead...

He gulped, wanting noting more than to run over and embrace her...

Oh, man...how do I tell her?

He licked his lips.

Staying at the entrance to his compartment, he watched Rainbow Dash, keeping his body hidden behind the wall.

How do I tell her...

A wave of ecstasy crashed over him as he breathed fresh air. He was alive. He could return to Rainbow Dash, and to his unborn child.

Resisting the urge to dance, shout, and punch in victory, he pulled back behind the wall, hidden from sight completely.

He heard Rainbow Dash claim that she 'needed some privacy', despite just pouring her extensive vocabulary out right in front of anypony.

Peter hurried back into his bed, trying to make it seem as sublime as possible...

Wait...I could just claim that I woke up...

He opened his eyes, just as the sound of gentle clopping, and heavy sobbing, reached the entrance to his compartment.

Rainbow Dash walked in, not looking at him, and pulled over the membrane. Sobbing, her eyes closed, she sat next to Peter, tears streaming down her face.

"Peter...I thought I would be able to have a life with you...

"I thought I would be able to be a parent with you...

"I wanted to be one...

"For the first time, I was actually willing to take a step of commitment...

"And then, Celestia tore it away from me...

"She tore it all away..."

She placed her front hooves on the edge of his bed, and Peter resisted the urge to touch her. He would probably just give her a heart attack...

She pressed her face into his death bed, and sobbed harder and harder, tearing holes in Peter's heart as he watched her.

"Peter...I love you...and now, I can't tell you...I can, but...you won't hear me..."

Peter gulped. He abandoned caution as he whispered to her. "Yes, I will."

She looked up, shocked, her eyes flying open, to stare into his eyes.

"Peter...you...you're..."

Her words died. She threw her forelegs around Peter, and held him close.

"Peter! You're alive!!"

Peter smiled, and wrapped his arms around her, hugging her in a tight squeeze as they both cried in ecstasy and never-ending happiness.

"I love you Rainbow Dash. I came back for you, and for our foal. I wouldn't let something like death get in between us, now, would I?"

She giggled lightly, and kissed him all over his head: his cheeks, his forehead, his nose, and finally, on the lips, drawing him into a deep, passionate kiss, that seemed to last for eons.

When they parted, Peter pulled her back for more. He loved her, and he wanted her to know it.

"I love you, Rainbow Dash..."

He kissed her, over and over again, eventually pulling Rainbow Dash onto his chest as they kissed, their love finding new heights that they never had before.

Suddenly Rainbow Dash pulled back her head, remembering the explanation Peter had given her for his...member being out, as a human.

"Well, I see you're excited to see me, Peter!"

She smiled at him, and he smiled back. Before drawing her into another kiss, he whispered one thing.

"You have no idea, Dashie..."

Celestia frowned down at the rather...disrespectful, letter.

"Oh, my...it seems as though they did take it the wrong way...but, then again, I expected this..."

Ditzy Doo smiled, and nodded. Celestia raised an eyebrow at the grey Pegasus. She seemed to be extra bubbly that evening...

"What is it, Ditzy Doo? Why are you so happy?"

She grinned, and Celestia simply stared.

"Gammel Hjerte is dead!"

Celestia blinked, then smiled, quoting a film that she had seen with Luna the other day.

"I love it when a plan comes together!"

The Elder of Death...

Was dead.

However, the Elder of Time...

Was not.

Gammel Hjerte nodded to Metall Kant, quite pleased with himself.

"So, you say that your Death counterpart is now behind the Gates of Death?"

"Yes, Metall."

The black pony sighed, relieved that he had not lost yet another accomplice...

"Good...when shall we retrieve your counterpart?"

Gammel Hjerte smiled.

"Oh, not for a while."

Metall Kant raised an eyebrow, and Gammel Hjerte grinned.

"We wouldn't want to interrupt his lovely conversation with our old...'friends', now, would we?"

Metall Kant blinked.

And smiled.

"No, we would not..."

Who are their old friends?
Hell, idk, I'm still looking through my countless OC's for possibilities...
