Continuity mistake: When Wolfe is outside holding the baby, the hood on Bethany's jacket is off her head, then back on, then off again, without him ever touching it.
Other mistake: When Valera hands Ryan the results from her comparison of the nanny and the baby the results list XY (male) for the sex chromosomes instead of XX (female). (00:32:30)
Character mistake: When Calleigh is with the medical examiner, she says that "Togo" is holding down the scene at the hospital, stating the actor's actual last name instead of Wolfe, his character name. (00:08:25)
