Sh*t just got interesting! It's about time they did something different and break away from the 'town in chaos' episodes, which has been tiresome for quite some time now. So, I nailed it in my assumption in my previous post that Sam wasn't dead. Not only was he not, he was alive and well.....outside the dome! Yep, the tunnel is some kind of portal that allows anyone that goes into the abyss to come out the other side in the town adjacent to the dome. So, Barbie is now outside as well, looking for help from his dad in getting "back to the dome". Really not sure where this is going, but at least it's got my attention again. I just hope the writers don't squander this opportunity here.
