TLove, that could work. I'd forgotten about Tony's dreams. Remember the one about his entering that old house and seeing that dark shrouded figure on the steps. Maybe that could be tied in with the ending somehow in a way you suggest. Maybe that figure could have represented Tony's mother.

I proposed the Jackie Aprile scenario because at the time that was the most sensitive of all the murders that would dramatically affect everyone. But now, with Ade's murder, maybe that's the one. But then I think that of those two murders it is probably Aprile's that the Feds would be more likely to learn about. But Carmela in torment over Jackie's murder - that could work.
