1. Yes, He grew up around Paul Vario and learned from him. He worked with other people when he later grew up but he still stuck with Paul for family dinings, etc..

2. Someone who was a made man, a captain, and later the consigliere of the Lucchese crime family.. well, I wouldn't say he had 10 people reporting to him.

3. Henry knew people who had money, he was around the big money makers and the big people who could give him a loan or something like that. Henry was a good money maker himself and whenever money wasn't in his pocket, He would go out and rob with his friends.

4. I agree with you. They should of hired a thug to do it and they did know where he was about but Henry co-operated valuable history to the feds and his reward was protection. Even if Henry was killed by a random, the feds would suspect LCN of doing it and would come down hard. They would go through their bills which they all probably didn't pay, and they knew their businesses. The feds can intimidate as good as The Mob.

6. Henry probably did kill someone for Jimmy or Paulie. It said at the ending that Jimmy never asked Hill to do a hit though Henry more than likely did.
