What if the shooter and/or rat are on board one of the helicopters and decides to hijack it with the pilot at gunpoint, forcing them to land near some body of water? It's just a random theory fueled by the current discussion.

I was wondering about the title of the chapter, "Our Doubts are Traitors". Do you think aside from the rat and Pippin situation it could also refer to how Burt is doubting himself, causing his hands to shake? Or Sauls doubt that anyone is concerned about Lizzie caused him to be a traitor (using the term loosely) in a way that he would break his promise to wait at LAX?
