Continuity mistake: Around the middle of the episode, Charlie Eppes and Mildred French are discussing in front of a board. She completes an equation and he adds a minus. In the next close shots, the minus disappears and reappears with angle changes. After three or four changes, a circle appears around the minus.

Amita Ramanujan: Charlie, where did you learn all this stuff about assassination?
Charlie Eppes: If I told you that I'd have to kill you.
Amita Ramanujan: Okay, seriously.
Charlie Eppes: Seriously.
Trivia: Judd Hirsch is an astro-physicist and can actually do the math Charlie does on the show. He caught the acting bug in school and chose that over physics.
Question: In a few episodes, the FBI agents will walk into a room and say "smell that?" and the reply is "shots fired", supposedly because they can smell the distinct odor of burnt gunpowder. Then they'll look behind a desk and find a dead body in a pool of blood. But wouldn't the smell of a dead person, or the blood, be way more overpowering? Or would it take too long for a dead body to start to smell? And how long would the smell of gunfire in an enclosed room last?
Answer: It takes 24-48 hours before a decaying body begins producing a decaying odor. It takes a number of days for it to intensify enough to be immediately noticeable when walking into a room.
