I mean there are so many flashbacks in every episode. You might see a flashback in episode 30 than another one in the next season that is even before the first. This seems like a filming nightmare. Do they just keep bringing people back to the same sets/filming locations over and over during the entire seasons? Did the just film 3 seasons of store from the same set and use them when needed? I'm trying to wrap my mind over how this is done.
