Factual error: When Dexter is punching Olivia's father in his left side, he says "That's your liver." Only the liver is on the right side. For a serial killer who routinely dismembers bodies, Dexter should know which side the liver is on. (00:42:50)
Revealing mistake: When Dexter stomps on Barry's kidney, you can see his foot doesn't even make contact with Barry's body.
Dexter: I am a father, a son, a serial killer.
Question: Dexter tests the blood on Miguel's shirt, to see if it's Freebo's. It looks like he's just using a DNA sequencer and the blood result comes back "bovine." Can a DNA sequencer differentiate which species the blood came from like that? Or perhaps he was using a different type of blood analysis machine? Is there an analysis machine that's capable of that? I thought the way to test if blood is human or not, "anti-human serum" is mixed with the blood to see if it will clot. So wouldn't the only way to tell it was bovine blood is to inject it with "anti-bovine serum"?

Answer: The short answer is yes, it could. but, it would have to be set up to analyze results to differentiate species. The sequencer will report the base pairs for any properly prepared sample, but interpreting the results is a software package. The software is available, but I would think it unlikely that an analysis package used in a forensics lab would have the capability to be so specific. More likely it would report "Non Human Sequences Found."
