Continuity mistake: When Blair asks Mitch "why aren't you answering me?" he says he got a weird message from Laura Barns. Blair replies "that's not funny" and Mitch replies "I'm serious." Then Blair gets a message from Laura, and when she switches back to Mitch's conversation, the last two entries, "that's not funny" and "I'm serious" have disappeared. (00:10:50 - 00:12:30)
Continuity mistake: When Laura Barns posts the photo of Val Rommel on Val's Facebook page with the curling iron, Facebook says the post is submitted in November. It should have been in March, the anniversary of Laura Barns' death.
Answer: Given the scene at the end of the film (the computer slams shut and Laura attacks Blaire) is in a POV, it should be assumed that it takes place through the eyes of Blaire.
