Continuity mistake: Will, Josh, Donna and Toby are in Josh's office talking about Toby's twins; Josh leaves the office with his arms by his side, but when the shot switches to show him coming through the doorway, he is clutching his books to his chest. There was no time for the change.
Factual error: In the television clip introducing the bombing in Turkey, the footage almost certainly comes from a Palestinian terror attack in the vicinity of Tel Aviv, Israel. Clearly visible in the frame is a Magen David Adom (Israeli Red Cross) ambulance marked with the Hebrew word "Dan" - a term for the area around Tel Aviv. The vast majority of raging fires that MDA ambulances responded to around Tel Aviv were the result of suicide bombings.
