I am giving all of you a small hint! It really is not a math question cause it is a question just to answer and mess with your head so now try to answer the question! lol
I wish my dog would not go outside and roll in the dirt! It not only gives her fleas, ticks and ear mites but it makes me sneeze having to smell the dirt on her! My poor allergies!
I think the barrier is the Elvish protection that protects Chris from anyone knowing who he is! And his Elvish genes might be protecting him also from the trauma he endured until he can deal with it himself! Plus maybe he needs his pendant to help heal him, so where is it?
