Jake mentions having been tortured by means of the "German chair." This method, a favorite of ISIS, involves laying a person on their stomach and placing a chair over them with the legs straddling the person's rear end, the chair's back toward the person's head. The arms are pulled up and tied around the chair's back, and the legs are also bent at the knees and tied up. The chair is then tilted forward toward's the person's feet, pulling the arms and upper body up off the ground at a cruel angle, sometimes breaking the back or causing other permanent damage (please note that no torture scenes are actually shown in the episode).
