Continuity mistake: When Gibbs is trying to talk Lt. Arnett out of jumping off the ledge, Gibbs is relatively close to Arnett in the middle of the wall when Ducky and Abby watch the live news report, but in real time, Gibbs is over at the far left corner of the wall.
Continuity mistake: The pill bottle the agents recovered from the house has the Doctor's name "Fleming" to search for. But when McGee searches the NCIS system, he spells the name "Flemming" and gets his results. As well, the scrip sheets for Dr. Flemming archived on the computer, contain several identification numbers - DEA (AJ0000000000), Batch (00000001) & License (C00000.) - not real numbers - so the prop master didn't even try to fake any of them.
