When Melinda is in the kitchen with the nanny and the bottle explodes in the microwave, the nanny picks up the dish rash and starts waving it in front of the microwave. When Melinda turns to walk out of the room, the nanny is shown picking up the dish rag again, even though she had it in her hand before Melinda left the room.
After Daniel's fatal accident (in which he was driving the car), when they show both the nanny and the mom with him, he is in the passenger seat.
