One lonely night, Starlight decides to release Cozy Glow from her stony prison, and plans to let out some of her frustrations on the vile filly until she discovers that Cozy Glow can't seem to remember who she is anymore, or much of anything else from her past.

Could this be yet another trick conjured up by this scheming pegasus? Can she really be trusted?

I am Spur. I'm a fourteen year old teenage filly who lives on the bayou with my Ma and Pa. Most of you know me because of my little sister.

My little sister was Cozy Glow. One of the most reviled villains in Equestrian history.

Some praise for My Sister, Cozy Glow:

I had just finished watching the finale, which killed my incentive to write, but upon reading this, I'm glad to say that it brought it back. Thank you for writing this, MicahDebrink. --IReadYouWrite

Man, there's so much emotional depth packed into each and every word. --Thought Prism

This fic is far outside my usual fare but I am still enjoying it immensely. --SockPuppet

Starlight Glimmer is a reformed cult leader who still struggles with social interaction.

Cozy Glow struggles to figure out this friendship business.

Who helps who?

(A/N-This is an AU take that plays with the idea that the Cozy from Marks For Effort was the real Cozy. School Raze never happened.)

Cozy was never in Tartarus. Cozy never met Grogar nor Chrysalis. Cozy is not in prison, except the one in her mind.

Cozy Glow woke up cold and confused. The last thing she remembered was being turned into stone. Twilight has presented her with an offer, either she can try and be reformed back into a good filly. Or spend the rest of her days locked in the castle dungeons for the rest of her life. The mane six will each take Cozy Glow into their homes to try and reteach her about the magic of friendship.

Queen Chrysalis, Lord Tirek, Cozy Glow and King Sombra are brought together to be part of the same team. Their task? Learn how to work together and defeat their enemies. They are not happy about it at all.

The story begins after The Beginning of the End - Part 1.

Many thanks to EverfreePony for her wonderful help with editing.

When Lord Tirek asks Cozy Glow what seems like a normal question, he has no idea the floodgates that will open... and how his relationship to the little villain might ultimately be changed.

A small bit of villainous sweetness inspired by both the dynamic of the Evil Trio and the cover art by soundwavepie.

No knowledge of the IDW Reflection comics is necessary to read this; it's just the framing device for a pair of parallel ponies feeling responsible for the actions of their counterparts.

Going on six years after the Reflections Incident that nearly tore apart both canon and inverted Equestria, the latter timeline is finally safe under Sombra's benevolent watch. No urgent correspondence has gone through the Mirror Portal since things re-stabilized, but it wouldn’t be much of a story if things remained that way.

This is an entry in the Snippet Series, an anthology of old oneshots I (and my good buddy Str8aura) wrote based around interesting pics I found. New ones will be posted every Thursday for the foreseeable future.

Sunset Shimmer's been informed of the Cozy Glow debacle, and now she's worried about Cozy’s human counterpart. Is it wrong to suspect someone based on their parallel self’s sins? Snappy character vignette that gives equal POV time to Sunset and human Cozy trying to figure out just what the other’s deal is.

Teen rating for depictions of mental illness and Cozy’s casual use of crass language. Cover image made by me slapping some EG vectors on top of each other in Microsoft Powerpoint.

Written reccomendation by a very reputable user

In Equestria, wrongdoing is generally punished proportionately. Misbehaving foals are scolded or grounded or spanked. Enemies of ponykind are destroyed or turned to stone or imprisoned forever in Tartarus. In neither case is any formal process of law involved.

But filly villain Cozy Glow is a special case that crosses the lines - her fate will be decided in court. The charges are piled up pretty high, too - at least she has a decent lawyer?

Note: Yukito already has a much funnier story by this title, but I honestly couldn't think of a more appropriate one and the system let me post it (perhaps because they have different tags)? So if you'd like to see a comedic take on the subject, check it out, maybe compare (just don't forget I'm a first-time writer).
