What if Jo Harvelle had a younger sister named Alexis? What happens when Alexis meets the Winchesters and what transpires when she begins to hunt with them? Starts in season 2, around the end of No Exit. AU that loosely follows the show.

Katelyn Taylor thought she knew what she was getting herself into when she agreed to a vacation in Moscow. But life has a way of twisting our plans, and Kat finds that out the hard way when she accidentally runs into Ethan Hunt. Now she's running from the Russian police, while trying to stop a nuclear extremist and not fall for a certain 'analyst'. Hey, no-one said life was easy.
