Holmes and Watson in “Unfinished Business”

I'm looking for a syringe.

Watson

What for?

I'm going to stab it into the softest part of Miss Ellison's thigh. Lots of nerve endings there. No one can fake their way through that.

Watson

If you wanted to know if she was really in a coma, all you had to do was ask. [lifts Yvette Ellison's arm and lets go]

That's okay but I can't stab her in the thigh?
