Corrina and her sister are sitting on the sofa chatting, in the scene just after the kids go for a nap. There are three shots from different angles, and in each one, Corrina's sister starts with her arm down by her side, and then puts it up along the back of the sofa, behind Corrina (like she's going to put her arm around her shoulders). It's really noticeable and makes her look very restless!
