Revealing mistake: When Ruxin's phone conversation with Kevin is overheard by Jenny, she starts an online chat with Ruxin. She sends her message, but almost as soon as she's sent it, for a fraction of a second we see "reply from Ruxin" appear on her screen, before the shot cuts to Ruxin actually seeing it and writing his reply.
