Continuity mistake: Dexter browses the book shelf at Travis' house. The camera pans across, revealing a book titled "Apocalypse Bound" situated at the right on the shelf. When Dexter takes the book off the shelf, it is then shown as the fourth book from the left. When he puts it back, the empty gap where it used to be now appears to the far right on the shelf.

Former Classmate: Come on, Dexter. It's hammer time.
Dexter: [internally] I have no idea what hammer time is. Or how it differs from regular time.
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."
