Visible crew/equipment: At the gravesite of Livia Soprano, the cast is dressed in black, but there is a man in a light green shirt to the side of the casket in front of the cast who is out of place. (00:39:16)
Suggested correction: This man is cemetery staff, lowering the casket into the grave. Watch as this scene continues, right after Carmela says, "He won't discuss it, he clams up," we can see this man at the bottom right corner of the screen, turning the lever for the device (00:39:30).
Knight in White Satin Armor - S2-E12
Corrected entry: Janice shoots Ritchie twice yet no-one hears the shots. Houses are close together in the neighborhood.
Correction: It's not a plot hole. It's possible people heard but didn't react. It's also possible they didn't really acknowledge to themselves or care that they might have heard gunshots. It's also possible that no-one heard. We don't see that anyone else was actually home in neighbouring houses.
Correction: I wanna know who doesn't care when they hear gun shots in a neighborhood? Especially one with houses close to each other.
