Factual error: The memory Jane has of the man who takes away all her memories holds a butterfly needle to Jane's arm. The butterfly needle is called that because it has 2 wings and a body in the middle. To use this needle properly, the person takes both wings up together to be able to slide the small needle in, but the person we see using it, doesn't do this - he holds the needle behind the 2 wings and then inserts it. Also, this needle is far too small to handle the bag of drug-filled fluid that is intended for Jane's arm.
