After passing out from the fire, dancing wildly on and within his body, resonating and turning him into a living torch, Toz was enveloped by a sphere of fire. Since he had lost consciousness, Toz was naturally unable to tell what was happening to him or his body. But, his last thought before he passed out was that it was a shame to fail and die when he was so close to the finishing line.
So, he was understandably surprised when he regained consciousness in the middle of his body melting and reforming itself. At first, his mind was so hazy that he couldn't even tell what was going on. But he eventually managed to figure it out, despite his mind not regaining any clarity.
Well, Toz didn't know if he had figured it out since his mind was a mess. But he also didn't think he would have been able to make sense of it if he had been able to think straight. It was just too weird and nonsensical.
