Carl appeared at the door. Oz's eyes widened as he took in Carl's soot covered clothes. Van Helsing didn't even bat an eye. He was used to it.
Carl smiled. "I've got it! It should work!"
"You ready?" Van Helsing asked the werewolf.
"I guess so," Oz said.
They entered the lab. Carl led them to a table holding a beaker and a syringe. "It's perfectly sterilized, not to worry," Carl said. He picked up the syringe.
Oz rolled up his sleeve and presented the scientist with his arm. He bit his lip as the syringe's needle penetrated his skin.
