Factual error: The Swedish subtitlers made Amanda's situation even more tragic, incorrectly translating her dead cellmate as her dead soulmate. (00:24:40)
Factual error: While Dr. Gordon is sawing off his foot, he only has blood on his hands and some on his shirt. Since the blood on his shirt was from splatter, that means he must have cut through a few veins or arteries, yet he has no blood on his arms or face, which should certainly happen when cutting through something like that.

Factual error: After the doctor speaks on the cell phone for the first time and the line goes dead, there is a dial tone. There is no dial tone on a cell phone. (01:09:30)
Answer: Jigsaw's traps would more than likely leave a person mentally unstable, which could result in Stockholm Syndrome, a condition which involves a victim sympathising with their captor. In fact, after Lawrence Gordon escapes the bathroom after severing his own foot, Jigsaw nursed him back to full health, thus gaining his trust (this is shown in Saw VII). He also plays mind games on people, which is shown in a flashback in Saw III in which he convinced Amanda to side with him. In her unstable state of mind, she realised that he was the first person in her life she could actually relate to, and thus became an accomplice.
