Ben worries about where Klaus has disappeared and decides to go look for him after yelling at his other siblings who shrug off the missing boy. However, when he turns up with nothing, something much worse comes to help him find Klaus. Set about a year or two after the season one finale when they are turned back into children. Okay, so basically the premise for this story's making is something that their father said to Klaus when he (spoilers) died at the rave: "You've only scratched the surface of your potential." Basically, this has become a theorized version of some of Klaus' potential brought forth through unconventional methods!
