Character mistake: The chemical structure that Lucy has to draw is structurally wrong in multiple ways. The hexagon that has the "OH" should have more bonds in it, and they failed to connect the carbon bonded to the nitrogen to the correct part of the carbon ring.
Character mistake: When the sergeant's partner gets shot and Chen calls it in, she says he got away in a black Buick, but the car was a Honda Civic. (00:10:52)
