I liked this episode. I don't know what is up with everyone. I was wondering what happened to Elam since witnessing him being attacked by a grizzly towards the end of Season 3. He and Eva were my favorite couple. So I was glad to have clarification as to what happened to him. Plus, Common is fine and he has an awesome voice.
Btw, to another reviewer, LSD, Lysergic Acid Diatholomide is a derivative from Ergot, a fungus that can grow, naturally, in rye or other grasses. It is one theory that the Salem, Massachusetts crazed witch hunt was due to a very bad batch of rye bread. So, yes, in a sense, Acid did happen long before Hell on Wheels time.
