Factual error: They used an EpiPen to bring Liv back but they're holding it backwards. The way it's being held, Ravi would have injected himself instead of Liv and she wouldn't be revived.
Abra Cadaver - S2-E7
Continuity mistake: When Liv is describing how the murder took place, there is a shot of Babineaux in which you can see the edge of Meers' wig on her head, even though it had been taken off a minute before. (00:36:30)
Abra Cadaver - S2-E7
Continuity mistake: When Peyton and Ravi are talking in the kitchen, there's bananas in the blender that keep changing position through the scene.
Continuity mistake: In the parking garage, when they review Regina getting shot, a bullet wound can be seen on her back before the gun is fired. (00:37:12)
Continuity mistake: The way Regina is lying after being shot dead changes when Ravi and Liv are there, her arms are positioned differently and the body moves relative to the lines on the concrete floor. The knife is positioned differently too.
Other mistake: When Liv is pretending to be Major and texting Rita at the end of the episode, the text messages appear on the wrong side. Rita's messages should be on the left and Major's replies should be on the right.
Physician, Heal Thy Selfie - S2-E12
Continuity mistake: When Liv takes and tweets her "celebratory selfie", she has a big smile with teeth showing. But in the picture shown, her lips are closed and no teeth showing.
