- While discussing the prevalence of heart disease, Dexter's projection of Harry tells Dexter "it got me." Although Dexter has been told (by Thomas Matthews) that his father committed suicide, the line doesn't conflict with that plot development because Harry actually did have heart disease. That's why he was in the hospital the first time when Nurse Mary tried to kill him.
- The deadbolt lock on the door to Sal Price's apartment had the keyhole facing inside, making the doorknob lock the only effective one.
