So I hadn't seen any of the episodes until tonight when they played them during the marathon. About the bugged picture, in one of the earlier episodes as soon as they walked out 50 yards away from the bank it cuts to Marcos' where they say that the reason why they can't hear anything is from either (I'm doin this from memory mind you) the device being underwater, crushed, or out of range. Now they did just say out of range but I'm assuming they meant the bank. Anyways I didn't think too much of it until they rode away in the ambulance & the bugged picture came back into the plot. When leaving the bank the first time they did walk into a tunnel so maybe that had somethin to do with it but they had driven so far away in the season finale that it just KILLED everything past that point. Am I the only one who saw this really awful mistake? And if I'm wrong someone please correct me!
