Plot hole: Chrissy is pushing her baby Jay in her pram into the school playground. Justine and Luke call out to her from an upstairs window, then come out to meet Chrissy. They come down from an upstairs floor to the playground in five seconds, which is not enough time.
Suggested correction: This might be a mistake, but it's not really a plot hole. The plot of the episode isn't broken because two characters travel a short distance too quickly. The time they take isn't a key part of the plot; it has no impact on anything.
