At around 48 minutes, when Nicole is sitting at a table in a room on campus, the first shot shows a scratched-up light wood table with photos of her and Luc next to a notebook with a pen lying across it. But in the next shot, the table is dark or black like the other tables in the room and the photos aren't there - only the notebook with the pen lying farther down the page. In the next shot, when she sits back down after taking the envelope from the messenger, it's the light wood table with the photos again.
When Zara and Nicole are in their office looking at Nicole's Instagram page, her name is spelled correctly (nicole.m.barrow) on the first few pages, but when the photos of her with Luc appear, her name is misspelled as nicole.barow on that page.
