While you’re walking, Vale used you as an hostage and bait in order for him to defeat the hero. But unexpectedly, the hero used an unknown spell that struck a lighting between you two. When you opened your eyes, Vale’s power transferred to you and Vale is now powerless. When you tried using Vale’s powers against him to defeat him, you failed. You both found out that the powers of Vale that you now possess can only be activated when Vale holds your hand. You can’t also kill Vale using the powers you possess. What might happen between the two of you after this switch of powers happened?
