I like the fact that Joe didn't know what jasmine smelled like. It's a type of reality that tended to get dropped later in the series.
I liked it for that reason, too.
"You don't understand! They were ALL alive!!" It seemed like rambling at first, but he means, I think, that the spirits matter as much as those fortunate enough to happen to be living, at the moment. Their lives were/are just as "real", and legitimate, as ours. So leave them be.
"They take their deaths with them to their graves... it's all they have." Another line that I only noticed during a sort-of accidental re-viewing. I've thought in recent years that ghosts might not really be the continuation of a person's entire self, but just a fragment, which might be one reason you usually can't reason with ghosts. They just seem to need what they need, and they're utterly single-minded, often being fixated on the one most troubling trauma or disaster in their lives. A ghost might be the fragment of a soul which is obsessed with her/his death, and which can't work out a way to "live" with what happened, because, being just a fragment, he/she hasn't got the inner resources. So they go around and around in a sort of obsessive thought-loop, forever, with no exit.
