This episode wasn't great, but it is important to the overall story as it gives more background to what happened to Jake & reveals Hawkins' connection to what is going on. It was surprising in some parts, but knowing what happens later, most of it wasn't all that surprising. Some questions still left unresolved:
1) Who does Hawkins' work for? Ravenwood?
2) Where is the bomb that he was supposed to set off & why Jericho? He was supposed to go to Ohio.
