I want to say yes but it's been so long since I read it that I can't say for sure. There's something in the back of my mind about reading a scene about him transforming. I could very well be confusing that with something else, though.
Wasn't the transformation scene when they had locked Wolf in that box? I really can't remember exactly but I feel that this is right.I vaguely remember that too. Watching his face as he wasdying.
