Continuity: The piece of paper with Kelly Gordon's case notes on has the sex as 'M' and D.O.B in 1959, Kelly is quite clearly not a man or 46! If these details referred to her father this would not make him old enough to have a daughter her age.
Factual errors: The ants that are attacking Nick Stokes are identified as fire ants. In one clip, these ants bite Nick and a CSI style close up follows venom from one ant's bite into Nick's heart. Fire ants actually release their venom through a sting from the abdomen; their bite is only to get a grip.
Continuity: When the person buries Nick they give him several glow sticks but later on he only has one with him.
