[Well, he will come back from the body, casually wiping off the blood from his hands, and will just calmly start to describe the situation, a lot of controlled fury in his voice.]

He was decapitated. Seems like a clean cut; not sure what was used for that. Someone cut a hole in the back of his skull and removed the insides of his head. I don't know what the point of that was.

The only other wound on his body was the stab wound. It did look like it was made with his sword, which must have been difficult, because his sword is not sharp. It went through his chest and there was an exit wound on the other side. There was blood on his hand, but not beneath his nails. I couldn't find any other cuts, but the blood on his hand makes me think he did use his power.

Maybe when he was stabbed or had his head cut.
