Alpha's Power

(From Demetrius's Perspective) 

"B-Blood?" she stuttered. 

"Hmm, it's just a matter of personal fascination, I suppose," I said. "I can control the blood within someone's body; like I can speed up the flow, or slow it down, or turn it off completely." 

"But if you do that..." 

"Yes, if I turn the flow off, they will die right away, or suffer from a heart attack," I said. "Isn't it amazing?" 

"... Amazing?" 

"Are you scared, my wife?" 

"It's not like..." 

"You are," I said, cutting her off. "Look at how your small hand is shaking. But why are you scared? Haven't I reassured you enough that I will not hurt you? You are the only person I will never hurt. I love you after all." 

"Do you use this power a lot?" she asked.
