Inside the wolf, Oz is far too emotional for a statement like that. It reminds him of those first years as a wolf when he'd had no control. A time when he was still figuring it all out and Willow would sit with him outside of his cage reading to the wolf. It's been forever since someone accepted him, wolf and all. Even Bay was about ignoring that the wolf was there.
That flicker of emotion gave the wolf more leeway. Now the beast is closing in on all fours. There's a flash of teeth, tongue flicking out in anticipation of fresh, raw meat.
