Mithias, the vampire hunter, stood motionless as he watched Martin control the blood and ignite it with the spiritual flames. As his brother consumed it, he seemed to grow even stronger, more inhuman, and perhaps slightly psychotic. He was more like 'Father' than he realized. 

Seeing Martin's outstretched hand, with the sickly blue flame in his palm, Mithias already knew what his answer would be. He reached forward and grasped his bother's hand, tight, and looked into his eyes with life, vigor, strength, hope, and defiance. The blue fire grew and covered the whole of Mithia's body, changing him into his vampire form. His grip on Martin's hand too strong to break, Mithias answered him with a slight grin, "Never." Seemingly in response to Mithias' will, the blue fire changed to regular colored orange flames that reflected in his eyes and burst from Mithias' back in a set of flame wings. Neither of them were burning, of course. Mithias held Martin's hand. "I'll tell you a secret, brother. 'Humanity' has nothing to do with whether or not you are human." With a smile, he finally let go and took off to the air toward the image of Terebithia. 

In the real world the temperature inside Mithias' cylinder started to rise.
