When Kelly is saying goodnight to her daughter, she is seen standing by the child's bedroom door turning off the light, however the light switch is clearly already in the off position.
At 24:04, as the mother leaves the kitchen running into the living room, a woman's face and left arm can be seen on the left side. She seems to be arranging the table.
When Kelly and her daughter arrive at the house for the first time since the accident, someone just out of shot is clearly shovelling the dust into the wind. You can see the head of the shovel to the left of screen when the camera shows the house exterior.
