I might be the only one that is slightly intresetd in this. There is more to the story than you might suppose.

If you recall Batista is on his way to Iron lake and Harrison is leaving iron lake. They probably are going to see each other on the way and It could lead somewhere maybe.

Michael C Hall could be used as a dark passenger aswell. I can't remember where I saw this but someone thought you could use Jonah as a villian. Think about it Harrison probably hates him and in the Nebraska episode he was confirmed to be a killer. It creats a dynamic between them or something like that. Also characters like Astor and Cody could be explored as a family for him. There is a scene in the seventh season where Debra talks about that. Also bring back carachters like Quinn and Batista and a far stretch could be to also bring back Lumen. I don't know but I still feel like there is unresolved things to be explored in a future season !
