Something bothered me about the scene when Silvio and Christopher visited the crazy elderly hitman family in Long Island. When they gave them the picture of Johnny Sack, whom they wanted to be killed, Tony was right next to him in the picture.

Now even though Silvio indicated which one was Johnny, these men seem like the kind of guys who are liable to make a glaring error such as killing Tony instead of Johnny. Or maybe even killing both of them.

Even though the entire hit on Johnny Sack was called off, these men could forget about this and go back to do the job. I have a feeling that whenever the series ends, Tony's demise will be because of these men.
