Unity O'Neill: When my energy hurt you...I tried to heal you...but I did not understand your injury. So I looked into your mind. I saw the mind... of a warrior. I feared it, as I feared those who destroyed my race. I tried to make you well before my mistake was discovered, before the others returned to destroy me. I understand now. Your deepest pain was not the physical injury I had caused. Your pain was from an empty place in your heart where Charlie once was. I thought if I could bring Charlie to you, it would make you well. I did not understand his death meant he could no longer exist as flesh and blood. Physical death does not have the same meaning to us.
