But somehow she thinks it's my fault that I'm bleeding.
I'm pretty sure she's a robot. That's why she has such a hard time understanding the relationship between stabbing and bleeding.
This also means that I am probably not going to survive. Most robots are malicious and vengeful, and my filthy teeth will only serve to aggravate the dentist further, so I really don't see how I have a chance. The only thing I can really think of is to wait until exactly the right moment and then throw water on the dentist, possibly causing it to short-circuit.
Now I just have to find a way to conceal the water so that the dentist does not become suspicious.
