" How did you bind me to you?”
The exchange of our blood.
Her heart slammed painfully. “What does that mean, exactly?”
The blood bond is strong. I am in your mind, as you are in mine. It is impossible for us to lie to one another. I feel your emotions and know your thoughts as you do mine.
She shook her head in denial. “That may be true for you, but not for me. I feel your pain at times, but I never know your thoughts.”
That is because you choose not to merge with me. Your mind seeks the touch and reassurance of mine often, yet you refuse to allow it, so I merge with you to prevent your discomfort. "
