Secrets and Lies shares the Pony Psychology Series TVTropes page.

One by one, Twilight and her friends must come to terms with the consequences of being the Elements of Harmony.

These stories take place in the intervening time between Season One and Season Two,
with the exception of Ditzy Doo: Muffins, which takes place early in Season One.

The series continues in the sequel, Secrets and Lies.

Pony Psychology has a TV Tropes Page.

A story lovingly ripped off from the Futurama episode of the same name.

Twilight gathers the girls to her basement to reveal her latest invention. Unfortunately, they get distracted by another of her inventions: the 'What If" machine, a device capable of answering any 'what if' question posed to it. Follow along as the mane six discover the improbable scenarios that could have been their lives.

A Cutie Mark is meant to represent the personality and special talent of each pony that has one. Cheerilee's flowers symbolize her desire to help her students bloom, and the smiles represent the cheer that she hopes to bring to their lives.

At least...that's what she tells everypony who asks.

[SEMI-SAD]

A botched viewing spell has sent Twilight Sparkle to Earth and into the care of Kyle West. Having been turned into a human, the local species, Twilight Sparkle relies on her host to help her as she finds a way back to Equestria. And, in the meantime, she decides to learn about humans and the world they live in; the good, the bad, the beautiful and the ugly.

Now With TV Tropes Page!

Twilight Sparkle's imagination as a child was unbelievable, probably due to all those books. Which also make up the amazing Fort Book, Twilightopia's first stronghold against the country of Armor! With the help of Captain Smartypants and Private Cadence, General Twilight defends her fort against her brother's advancing army of one!
A tale of Twi's childhood told from her point of view.

Inspired by the cover picture.

After traveling Equestria and finding no place she belongs Trixie returns to the one place that felt different; Ponyville. She has chosen to swallow a little (just a little) bit of her pride in order to ask the only pony to ever have impressed her for help. She wants Twilight Sparkle to become her teacher in magic...and in the ways of friendship. She hopes to improve herself, but she keeps having these second thoughts...

This story is told while alternating viewpoints between Trixie and Twilight Sparkle. The ~~~~ symbolizes a perspective change.

This has not been forgotten. Update coming soon!

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?
