There are still a lot of unanswered questions. First of all there is a broadcast on air which shows people running and all. After Jake and Heather find a guy in a medical store he tells Jake that "THEY" were coming. And Dale brings the food from the train all the way to the store. But i wonder how he could have done it when he said that the Train was 5 miles away. I mean he is still too young to be driving something and gas is running low everywhere.
The final thing is what is this Hawkins guy up to. He knew the guy Jake and Heather picked up and he uses this freakish laptop. I think he is planning to blow Jericho off.
So all and all the episode was good.
