The killing of Chris' dad's alleged killer. Didn't get this, seemed a weird story line that was never brought up again. The guy set it was a set-up, I couldn't tell if it was the killer or just someone Tony wanted to go.
I always thought that part was weird because fact is if it wasn't his dad i'm sure Chris would've killed him anyway. Possibly it was to get more loyalty from Chris, by allowing him to do it instead of quietly giving it to say Paulie and never telling CHris of his existence. As Chris says anyway it doesn't matter in the end because Tony wants him dead.
