When Samir is looking at the family photos, he closes the bedside table drawer. In the reverse shot, the drawer is open.
A CIA safe house (or any safe house for that matter) would not authorize those in protective custody to have outside contact that isn't approved. They would never provide a protectee with any device that could communicate. The CIA would know better.
There is no way that the hostages wouldn't have gone through complete physical examinations, including blood work and toxicology reports upon returning to the U.S.
When Dr. Nadler (portrayed by Matt McCoy) receives the meds he asked for from Suleiman, Suleiman reminds Nadler what he asked for, antibiotics, acetaminophen, iodine, etc. Back in the "dungeon" where the medical personnel are held captive, he shares the medicine with the other team members, and then gets up to give some meds to the previous Arab terrorist cell leader who was usurped by Suleiman, and one of the medical team members asks Nadler what he is giving to the Arab? Nadler's answer is "he has had a fever for three days, his arm is broken, and....an aspirin tablet." This is incorrect, since Nadler neither asked for nor received aspirin (which is the most common trade name for acetylsalicylic acid), he asked for and received acetaminophen, which is the chemical and generic name for the medicine commonly known as Tylenol. Both are pain relievers and fever reducers, and both have chemical names which begin with "acet," but otherwise the two medications are quite different.
