Twilight injected the dead rat with the solution--a solution, she corrected herself, one of thousands she had tried over the centuries. She watched it intently, hoping as she always did that this would be the one.
And, as always happened… well, nothing did.
Twilight sighed and rubbed the bridge of her muzzle. Another night of failure. She frowned. There was no point being defeatist now, she had invested too much into this.
She turned to write notes of the experiment down. As she brought pen to page, she heard a rustle. Her eyes shot wide and she grinned like a child at a carnival. Something different. Something new.
The rat was alive again.
"Yes yes yes yes yes!" Queen Twilight Sparkle jumped up and down, happier than she had been in a long long time.
She walked over to the special nitrogen and magic rich freezer and smiled. Through the viewing window she looked at the deceased form of her beloved.
"Soon I'll hold you in my hooves again, Rarity."
