SC, there's been alot of speculation that Capone hit Torrio to motivate him to move on.
In the restaurant, some of what Nucky told Totino had an insincere quality to it. So, I think Nucky had Totino murdered because he considered him a liability. Also, I didn't get the look they gave to the picture on the wall.
And yes, that guy was a Dabney Coleman look alike.
The picture on the wall in the restaurant was Nucky's actress girlfriend who was killed in the explosion in Atlantic City a couple of seasons ago.
