So sad Richard is dead, mainly for his wife and Tommy. I loved him as a character and I really wanted him to team up with Nucky long term as an enforcer or something but was still a great story arc.
Chalky is going to be really interesting next season, so will the Chicago story line. Nucky and Will have power in Atlantic City any more so it will be interesting to see how they rebuild that. Great finale but as others have said, bittersweet.
