In the clip, Rick and the survivors rolled up on a barricade of vehicles. After some discussion, Rick decided to move the vehicles so they could go on through, but put the vehicles back so as not to alert the Saviors of their movement. In the midst of moving, Michonne made an explosive discovery and the scene ended with a sweaty Rick checking out a chain of explosives tied to a device. I kept thinking while watching that the task must be such a long thing to accomplish! Getting all of those cars moved would take an hour alone, and then rolling them back? I’m getting off task here, obviously, and the important thing to focus on with this Walking Dead footage are these rigged explosives. Of course, those who are putting their thinking caps on already know where they came from.
