Everlasting Love.

The familiar clickity-clack of Tuck's cart towards Ponyville got the attention of Applebloom, who was all the way grown up now. But she ignored it and continued walking with her kids. It had been years since Tuck last visited Ponyville, he wanted to see if Twilight obeyed his wish, or if she had followed the course of life. Tuck headed towards the graveyard, where his old house used to be. He found a gigantic plot of a group of friends. The line of headstones read:

Pinkie Diane Pie

  1958-2014

"The Funniest Pony Ever."

Rainbow Daring Dash

1956-2012

"She Just Had To Keep On Daring..."

Flutter Sane Shy

1959-2013

"The Kindest Pony."

Rarity Sapphire

1954-2011

"Everypony Misses Her Style."

Applejack Daniel

1960-2020

"She Is Apple-Bucking In Heaven."

Spike

1959-2002

"The Best Assistant Ever.

And as Tuck got to the last grave, it started to rain...which was good. Because as Tuck read the last tombstone he began to cry, and the rain covered his tears. The Last Tombstone read:

Twilight Shimmer Sparkle

1955-2014

"To My Darling Tuck, I Will Always Cherish You."

"So...she has been gone 26 years..." Tuck winded up the musical box, and placed it onto Twilight's grave. Then, Applebloom  appeared behind him. "Did ya'll know Twi and mah sister?" Tuck stared at the grave. "Yeah, We were great friends, me and Aj, but me and Twi?We had an Everlasting Love."

And With that, they both walked off...

   With the faint sound of the music box twinkling in the rain.
