The scalpel entered him easily, he didn't really notice at first either, looking down at the scalpel in surprise at the sight of his own blood.  That was strange, no one had ever stabbed him before.  Looking at the 'Doctor' quizzically, he tilts his head nearly like a dog would when confused.  He shuts up and as he is about to back up when the girl stabs him in the back with...  Something small.  His face contorts with pain, he grips the hand of the Doctor around the scalpel, the sharp but very small blade cutting into him.  The blood makes the Doctors hand slim, he had no idea that it was so close to truly hurting him.  His shoulders twitch slightly in pain, his face twitches again as he digs fingers into the man's wrist, right where the bones fall off and connect to the arm, the complicated bundle of tendons tight under his fingers.  Tilting his head the other direction a grin fills his face, wicked and mean, pressing fingers deeper into the pressure point, hard pressure robbing the hand of its power with every ounce of force Thomas puts into the hold.
