Character mistake: Nicole Wallace has murdered and stolen the identity of Professor Elizabeth Hitchens, who was Australian. While speaking to Detective Goren she refers to her life in Melbourne, pronouncing it the American way : "Mel-born." No Australian would do such a thing - it is pronounced "Melbun." A detail-obsessed knowall like Goren would pick up on that immediately.
Continuity mistake: As Goren and Eames are questioning the Botox guy, Goren takes several syringes from the kit and begins tossing them like darts into the notebook on the table. He does this with at least 5 syringes before the camera angle changes, and when it cuts back to him again there are no syringes in the notebook and he has a fresh handful of them that he begins uncapping and tossing all over again.
Continuity mistake: Goren is interviewing Roger Stern in the cells at the end of the episode. The bars on the cell are straight with curves where the bars cross. In some shots when you look at Goren the bars are bent from one cross section to the next. This changes from shot to shot. (00:34:00 - 00:39:00)
