Tabula Rasa - S1-E3
Revealing mistake: When Kate is with Ray in his pickup, he wears his wedding band on his left hand, and his right arm is prosthetic. After the wreck, when Kate pulls him from the cab and onto the grass, he wears his ring on his right hand (which is supposed to be prosthetic); the door and Kate's bracelet are also on the wrong side - obviously a flipped shot.
