You hit your noggin, wake up, and have gained Acquired Savant Syndrome. This condition unlocks savant skills at an almost prodigy level of expertise, and is typically caused by a head injury to the left anterior temporal lobe, and has been artificially induced before. What's your skill? What's the one thing, if anything, that you'd want to unlock? Language skills? Music, perhaps? The possibilities are limitless, and I find it a incredibly interesting phenomena. I personally would hope for language skills, as one of my dreams has always been to be able to travel anywhere and connect and communicate with locals.
