The language barrier is a particularly scary and isolating aspect of the case, even when malice isn't in play. In Episode 4, a man who may have encountered the captive Bergdahl in his capacity as a cook relates that an American prisoner was asking him for something, but he couldn't actually tell what it was, so he just kept bringing him small things hoping one of them was it — some salt, some Tylenol, a blanket. These men were strangers, potentially putting their safety on the line out of basic goodwill — but we never find out what the prisoner was asking for, or even if it was Bergdahl at all.
Episode 9 reveals that the Obama administration assured Bowe's parents that he would not be charged after his rescue. A year and a half later, Bowe faced a general court martial up to and including a life sentence. After being rendered nearly incapable of coherent speech by years of isolation and torture, Bowe is still facing punishment.
There are some very blunt, depressing descriptions of torture, as well as a brutally honest description of how difficult recovery from something like that is.
The very end of the season is bittersweet. Koenig reveals that despite the whole crazy political, legal, and military mess that was unleashed by Bergdahl's capture and rescue, Bowe himself has had to more or less return to normal life and hope for the chaos to resolve itself.
Koenig: Bowe and the army are adversaries, legally speaking, but Bowe is still a soldier. As soon as he was rescued, somewhere in a government office, someone filled out a department of the army form 4187, and they changed Bowe's status from 'missing, captured' to 'present for duty.' After knocking down this huge long serpentine of geopolitical dominoes, Bowe was assigned to an office job on his base in San Antonio. He's fighting the charges against him, which means he waits, a lot longer than he thought he'd have to. But waiting is something Bowe knows how to do.
