From The Grey House:
“What’s the word doc?” Charlie was hanging at the end of the van, not really wanting to talk to the vampires.
“Bullet’s out. Just cleaning the wound.” He had a bottle of peroxide in his bloody gloved hands.
“How long before he can change back?” This was from Rebecca who was still staring at Orlando.
“He’ll rip himself open no matter when he changes. If he changes later, he’ll rip open the stitches. If you can get him to change now, that would be of great help to him and me.”
