Personally, I would have felt much better if Bohannon had put a slug in his brainbox -- just to make sure. The Swede has had a nasty history of survival.
Triple tap for making sure. And then possibly hacking in pieces and burying in several locations. That's what I would have done. Just to make sure.
Why they had to wait all this time to show these last episodes? I don't know, but I glad and very grateful they are finally coming out. Swede was a wonderful nemesis and wonderfully played by Christopher Heyerdalh. So, I'll raise my hat for him and Anson Month for giving this ending their everything.
By the way, I loved hearing Bohanna'n claiming to be the Devil, as it has portrayed for so long by the intro. This is best western in the small screen, and a rare treat.
