Character mistake: When the wife of Lennie James (number 147) says to her husband 'You left the door open' (just after the incident with their daughter), this is wrong. Rewind a few minutes and you will see that there are 3 people: 6, 313 and 147. 147 leaves when his wife says 'Cake's out of the oven!', leaving 6 and 313. 313 leaves, with 6 alone. Then Number 6 leaves the backyard with the door open. Even if she meant the door to the house, he would have to go through it last.
