This story has been riffed in Doctor and Ditzy's science theatre by Rixizu. You can find it on his user page here

Spike has been missing for three years. Why he disappeared is a mystery to everypony. What caused him to leave in the first place, and why is he suddenly back now? He's acting cold towards his old friends and won't reveal why. He's lost his love for Rarity and is treating everypony he comes across the same way Gilda did.

Opening theme for this story is: Constellations - Sound of the Aviators

Rated: Teen for language and potential sexual outcomes.

Warning: Self-harm is described in this story. If you are prone to self-harm or know someone who is and feel uncomfortable reading about the subject, then I don't recommend reading the story.

Have Spike take the C.M.C.'s on a tour of Canterlot so that they don't interrupt Braeburn's ceremony? It was such a simple solution, but even the best laid plans can go awry. Now, Luna and Applejack must contend with some unfinished business from the princess's past as Twilight deals with the fears and concerns of two little fillies... and two little dragons.

Future Wonderbolt, coolness incarnate, and all-around awesome. Is it any surprise that everypony wants a piece of Rainbow Dash?

Not that she wants anypony to take a piece, mind you. All she wants to do is live her life. That's something she finds pretty hard to do when everypony she meets falls in love with her on sight, though...

A day-in-the-life story about an awesome pony in a crazy world.

[Enjoy! I just HAD to write this.]

[No editing or proof-reading done, but did my best]

[Well damn? I got semi famous.]

The friends we take for granted are often the ones that leave the largest impact on our lives. When Spike falls seriously ill with a mysterious disease and the ponies strive to nurse him back to health, Twilight Sparkle comes to grips with this very realization about her number one assistant--and friend.

EDIT: So this little story made it on Equestria Daily on 10/8/12. Now please excuse me while I pass out on Rarity's fainting couch while murmuring a soft Fluttershy "...yay."

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!

Twilight Sparkle, Princess Celestia's most prized and faithful student, is being sent to Ponyville to learn about the magic of friendship.

And she's not happy about it.

Hear what Celestia has to say back! Check out the spinoff:
