Asher was, not to put too fine a point on it, starving. He was also lost, confused and in pain.

It was perhaps not surprising that when he opened his eyes and saw Jean-Claude his reaction was not one of relief. It was quite probably rather surprising, all things considered, that he started to laugh.

How he'd ended up, filthy and near mad with pain and hunger and grief, on Jean-Claude's bed, was anyone's guess. It might even have been the psychic city.
