Did he die? I thought we were left watching him and his family reunited for a meal, with the threat of a hit man at the counter - wide open for a follow-on. Whatever, he was a 'Made' man, both in the role and as a guy; a sad loss to his family and those who marvelled at his 'believability'. A class actor, I'll never look at a Singing Bass without thinking of how it haunted him, what a Pussey, RIP.
I think he is killed when it blacks out. Earlier on in that series, When Tony was fishing on the boat with Bobby Bacala they were talking about what it would be like when someone was capped. They determined that the 'lights would go out and you wouldn't hear a sound'.
