Twilight Sparkle isn't feeling too well, and it is up to Princess Celestia to nurse her back to health. It would be a simple task, if not for the fact that her student was thirteen years old with an uncontrollable amount of magic.
To make matters worse, six years ago Celestia was forced to shrink Twilight to 1/100th of her size so that her untamed magic wouldn't be a threat to Equestria. She would have to remain tiny until she would learn how to control her enormous power.
But surely a two millenia old alicorn with enough magic to destroy a small mountain can handle her littlest, fragile and most magical subject... right... right?
This sidestory takes place between chapters 4 and 5 in Celestia's Tiny Student.
Special thanks for pre-reading to ambion, I took some inspiration from his story called melt, worth checking it out for additional dose of cuteness.
