Tony killing his cousin just struck a memory of a Don ordering the death of his brother. Sound familiar?

I was hoping for an all-out-war in this season finale. I hate when the previews deceive you. Happened that way in season 3, and 4. Enough is enough.

While Johnny and tony are talking, Tony freezes and takes off. Then Johnny turns and sees the Feds, who I didn't recognize at first sight until I saw the FBI initials. That part was hilarious. Somebody in the Brooklyn based Mob family was an informant.
