Who do you think a**hole Savior ran into in the woods at the end?? I think it has something to do with the helicopter. But then I don't know, because he seemed to recognize whoever it was. Same with the other missing Saviors, the one's who were supposed to deliver ethanol to Hilltop that never showed and then I think there were more missing who were working on the bridge construction. Someone is stockpiling Saviors!
I was thinking the jerky savior ran into Dwight. I don't think we know where he is. Another theory I have read was that it was the whisperers. The show runners have said we will see the whisperers this season.
