The first box car contained Garret's group and was prefaced by "THEN", meaning before today. Evidently they had been taken hostage by an equally evil group some time ago and whatever events happened then turned them into what they are today.........
help me with some details: who was the long haired guy trapped in the box car that they freed? who is Mary to him? I guessed Mary lived at the end (couldn’t quite tell if it was her but I think so) and the girl that got drug out of the car; who was she and who were the guys that did that.
