And castle...why would a character need to have another force user come along and say "oh by the way your force sensitive"? That makes no sense at all...did Anakin need qui-gon to tell him he was force sensitive before he became an awesome pilot, or developed the ability to predict things that was so strong his mother noticed them?
Also, as a sidenote, I just want to point out that I find the Force to cause a character to gain a lot of attention due to natural Star Was feel. I go by the 'all-or-nothing' rule; either everyone gets the cool Force, or no one does (with the latter meaning the restrictions, and the prior meaning "Have fun, kiddos!").
