Kate understood his concern and could not blame him being very upset. She did not know he was on the verge of killing himself. "If you turn dark and show your fangs to me; I will use everything in my power to fight you. I will not allow anyone to use silver on you. I will do what I can to get you to a safe place where you can be held until you are ready to come home. If we need make this room more suited to keep you safe, let me know. Do you have anything that could harm you should you be in darkness and wish to do harm to yourself or others? Tell me what I can expect to happy if you so did turn? Alyx, I have never been around vampires under their powers. I know what vampires have great strength, they can move faster than time for short burst, some can defy gravity. They can climb walls. The rest in  fairy tales and ignorance." Kate was close to see the blood on his shirt and his skin was broken at his collar. 'Did you harm yourself?" She rubbed his back and this calmed and he relaxed at her touch.
