Grenade
1I just thought of this, I'm not sure which season it is in and I don't have all the seasons to rewatch but perhaps somebody could find this information out. Inside the Sopranos home is a hidden compartment, the one Carmela got the AK-47 out of in episode 1. Later on, possibly in Season 1 when they have to do house cleaning, that compartment is opened again and a grenade is see in there. Later in another one of the seasons, the compartment is opened and the grenade is not there anymore. Just digging for something here, perhaps Tony brought along that grenade or two along with his AR-15 for the finale. If anyone knows what i'm talkin' about please post.
