He was kept in an old house for a week, hung from the ceiling on hooks like a carcas. I would have bled him when I felt the need, toyed with him... his power kept him alive, if barely.
I had to search him out, and when I found him.. it was too late. I tried to heal him with my blood, but he was too far gone. I woke him enough to let him make the choice himself, and... I did like he asked.
He would barely eat what I brought him. He will have to hunt, tomorrow. I'm still not convinced he will have the ability.
