Did You Know?


QSO is part of the 'Q code' system, which was invented for early radio-telegraph communication. The Q code system was created to make early radio communication more efficient. Back in the day only Morse code was used, which was quite inefficient. The Q codes were 3 character codes that related to commonly asked questions and or replies. The code 'QSO' means: "Can you communicate with ... directly (or through...)?" See more »


When Root gives Fusco his 'exit plan' documents, there's a Maryland Driver's License for his son included. It shows that he is 11 years old, and got his license at age 10. (and 5'5" tall, weighing only 75lbs...) See more »

POI Double Header Part 1
25 May 2016 | by awoolforkSee all my reviews

QSO was the first of two great and highly intense episodes that aired on tuesday.

This episode ruled in every word. This was easily for my money, the 2nd best episode of the season ( sorry wasn't 6741 level ). The unique way of taking a number and having it crossover into one of the main archs of the show in a very dark manner while also pushing the intense story of Shaws Arch is incredible.

Sarah Shahi is running away with the season 5 mvp award so far and it would take another cast member bringing the noise to take it from her. There are scenes where she just frightening and dark without even saying a single word. Outside of the the main story of The Machine vs Samaritan, Sarah's run this season has been the best part of season 5.

Highly recommend this episode and for an episode that didn't have a lot of action sequences it trumps most that do and thats saying something!
