Continuity mistake: When the family is on the plane taking their seats, the wife goes to sit with her husband and sets her purse and clothing onto the seat in front of them, however you see the clothes slip off the seat and only the purse remains. In the next shot of the seat in front, the clothes are on the seat on top of the purse, without any character picking them up.
Factual error: Throughout the episode the military are shown carrying Israeli Military Industries Tavor assault rifles. Israel does not sell weapons to any Arab states. Especially if said state already allied with the US and is thus buying its weaponry from the US.
Revealing mistake: When John Tucker calls Bassam, you can see that he is not calling anyone, because the iPhone home screen is visible. (00:05:50)
Answer: Nusrat was killed because she knew the secret of Jamal's treatment of her, the pregnancy that was not Ahmed's, but Jamal's, etc. She was a liability to the al-Fayeed family who could be used by their enemies to erode their power. Also, it was Ahmed who killed Jamal, not Nusrat.
